It describes the UPS system, introduces controls and indicators, and describes available options. Figure 1-1 shows the HA32A UPS. Figure 1-1 HA32A UPS 1-1 1-2 HA3000 SERIES UPS INTRODUCTION 1.2 SYSTEM DESCRIPTION The HA3000 series Uninterruptible Power System (UPS) is a three-phase on-line interface between a building's utility power distribution system and the customer 's critical load. The UPS is designed to ensure a continuous flow of clean electrical power to critical loads by addressing common power problems associated with utility ac power. These problems include spikes, electrical noise, sags, brownouts, surges, dropouts, and frequency variations. In the event of a power outage, the UPS will provide battery power that is adequate to complete an orderly shutdown of equipment or to turn on a generator. The HA3000 series UPS is available in kVA ratings of 20, 40, 60, and 80 kVA and can accept three-phase input power of 208, 220, 480, and 600 Vac. The basic HA3000 series UPS consists of a HA32A UPS and a HA32B UPS Battery Cabinet. Options available to expand the HA3000 series UPS include the HA32C/D/E UPS Auxiliary Cabinet, the HA32J/K UPS Distribution Cabinet, the HA33D/F UPS CSA Cabinet, the HA320-Ax Remote Status Panel, the HA320-A3 Remote Alarm Panel, the HA320-B1 Smoke Detector, and the HA320-C2 DC Ground Fault Detector. Figure 1-2 shows a typical layout diagram of the HA3000 series UPS. Figure 1-2 HA3000 UPS Layout Diagram The HA32A UPS and its auxiliary equipment are listed by Underwriter 's Laboratories, Inc. (UL). The addition of a CSA listed HA33D/F cabinet makes the HA32A UPS CSA compliant. HA3000 SERIES UPS INTRODUCTION 1-3 The major components of the HA32A UPS include: · A rectifier/battery charger · A transistorized pulse-width modulated (PWM) static inverter · A continuous-duty rated static switch that automatically transfers the load to and from the bypass ac input source and the UPS inverter output · An internal manual bypass function comprised of three separate switches that allows the critical load to be operated from the utility source · A battery system housed in an external matching enclosure The HA32A UPS uses microprocessors to control operation of the rectifier/battery charger; transistorized pulse-width modulated (PWM) static inverter; and continuous-duty rated static switch to ensure optimum performance for all line, load, and operating conditions. In addition, a microprocessor-based diagnostic system assists in troubleshooting faulty assemblies for replacement in order to minimize service time. Modular construction throughout the HA32A UPS facilitates maintenance of the system. A system status and control panel (SS&CP) provides controls to select system operation, and indicators that allow system performance to be monitored. A liquid-crystal display (LCD) is used to display system operating parameters and step-by-step operating instructions to the system operator, and to provide a diagnostic capability to assist in troubleshooting. The built-in UPS monitor software is programmed to display messages in five languages--English, French, German, Spanish, and Italian. A single-line diagram of the HA32A UPS is shown in Figure 1-3. Figure 1-3 HA32A UPS Single-Line Diagram 1-4 HA3000 SERIES UPS INTRODUCTION 1.2.1 Rectifier/Battery Charger The rectifier/battery charger consists of: · AC Input Circuit Breaker (Q1): The ac input circuit breaker provides mechanical isolation and electrical protection for the input of the UPS. · Input Autotransformer: The input autotransformer is used to match the external ac input source to that required internally for the UPS. · Power Module: The power module is a plug-in unit that converts incoming ac power to a regulated dc output voltage. The regulation is carried out by controlling the SCR conduction angles, allowing the rectifier/battery charger to supply a stable dc voltage (± 1%). The dc voltage is filtered by a capacitor bank. · DC Shunt: The dc shunt is used to monitor the battery charge current and provide data for regulating the dc voltage at the desired level. Battery current is normally limited to 0 : 1 C 10 (that is, 1/10th of the battery capacity specified for a 10-hour discharge rate). 1.2.2 Static Inverter The static inverter consists of: · Power Module: The power module is a plug-in unit, used to chop the dc voltage to obtain the PWM waveform at the primary of the output transformer. A single power module is used for UPS systems having an output rating of 20 kVA. UPS systems rated above 20 kVA use three power modules, one module per phase. · Inverter Transformer: The inverter transformer is a full-isolation transformer that provides input/output electrical isolation for the UPS, the required output voltage, and the required inductance for the ac output filter. · AC Output Filter: The ac output filter is used to achieve a computer-grade sine wave output voltage waveform, with a total harmonic distortion (THD) of 4% maximum (3% typical). 1.2.3 Static Switch The static switch transfers the load from the UPS inverter output to the bypass ac input source or from the bypass ac input source to the UPS inverter output, without any interruption to the load (provided that the UPS inverter output is synchronized to the bypass ac input source). These transfers take place automatically upon inverter startup or shutdown. The static switch is rated for continuous duty, and is of plug-in construction for easy maintenance. The delta-RC network protects the static switch against high-voltage spikes and surges by absorbing the excess energy. The delta-RC circuit network is protected by fuses, and any failure of these fuses is displayed on the SS&CP LCD. 1.2.4 Manual Bypass The internal manual bypass function consists of three switches that, when operated as specified, provide a make-before-break transfer of the load from the UPS inverter output to the bypass ac input source or from the bypass ac input source to the UPS inverter output. This feature allows the critical load to be operated from the utility power source. HA3000 SERIES UPS INTRODUCTION 1-5 The three internal manual bypass nonautomatic switches are designated as: · Bypass (MAINS2) Input (Q4S) · UPS Output Isolation (Q5N) · Manual Bypass (Q3BP) For startup or shutdown of the equipment, correct operation of the three switches is shown on the liquid-crystal display (LCD), which is located on the system status and control panel (SS&CP). 1-6 HA3000 SERIES UPS INTRODUCTION 1.3 PROGRAMMABLE CONTROLS AND INDICATORS All HA32A programmable controls (excluding circuit breakers and nonautomatic switches) and indicators are located on the system status and control panel (SS&CP), which is shown in Figure 1-4.

Figure 1-4 System Status and Control Panel (SS&CP) HA3000 SERIES UPS INTRODUCTION 1-7 1.4 BATTERY CABINET Each HA32A UPS requires a separate HA32B UPS Battery Cabinet, which contains batteries having sufficient ampere-hour (A h) capacity to support the UPS and its intended load for the protection time specified. The UPS Battery Cabinet features sealed, maintenance-free, recombination type batteries. The batteries are maintenance-free because they do not require that the electrolyte level or the density of the electrolyte be checked periodically. The UPS Battery Cabinets do require that the interior of the assembly, including the exterior surfaces of the individual batteries, be kept clear of all foreign matter including dust. The integrity of the individual battery connections must be verified annually. The HA32B series UPS Battery Cabinet is explained in Chapter 3. 1.5 OPTIONS Section 1.5.1 through Section 1.5.8 introduce the options available for the HA32A UPS. 1.5.1 UPS Auxiliary Cabinet The HA32C/D/E UPS Auxiliary Cabinet provides the means to incorporate two separate features into the HA3000 series UPS (see Chapter 4). The UPS Auxiliary Cabinet attaches to the right side of the HA32A UPS enclosure. The UPS Auxiliary Cabinet enclosure will accommodate right-side cable entry when required, which may occur if the UPS is installed in an equipment room with limited space. The UPS Auxiliary Cabinet may include an input isolation transformer, an input harmonic current filter, or both, depending on which features are purchased. The input isolation transformer provides complete electrical isolation between the utility line and the input of the UPS (rectifier/battery charger and battery). It also provides extra protection against electrical noise and ground faults. The input harmonic current filter limits the amount of harmonic current fed back into the input ac power source to less than 10% when the HA32A UPS is operating at full load. NOTE Systems with a 600 Vac input require an HA32C-Ex or HA32D-Ex UPS Auxiliary Cabinet or an HA33D-Ex UPS CSA Cabinet with an isolation/step-down transformer to step down the 600 Vac to 208 Vac for use with the HA32Ax UPS. 1.5.2 UPS CSA Cabinet (Canada Only) The HA33D/F UPS CSA Cabinet provides the means to make the HA3000 UPS compliant with Canadian Standard Association (CSA) requirements. This is done by providing a mechanical contactor that opens in case of a power failure. This prevents the flow of power from the inverter output to the bypass ac input branches in the event of a static switch SCR failure (short circuit). See Chapter 5 for more information on the HA33D/F UPS CSA Cabinet. The UPS CSA Cabinet attaches to the right side of the HA32A UPS enclosure or the right side of the HA32C/D/E UPS Auxiliary Cabinet enclosure. The UPS CSA Cabinet enclosure will accommodate right-side cable entry when required, which may occur if the UPS is installed in an equipment room with limited space. The UPS CSA Cabinet may also include an input isolation/step-down transformer. The input isolation/step-down transformer is used for systems with a 600 Vac input. The 1-8 HA3000 SERIES UPS INTRODUCTION transformer secondary voltage is 208 Vac. The transformer supplies both the main ac input (MAINS1), and through the mechanical contactor, the bypass ac input (MAINS2). The transformer also provides complete electrical isolation between the utility line and the input of the UPS (rectifier/battery charger and battery). It also provides extra protection against electrical noise and ground faults. NOTE Systems with a 600 Vac input require an HA32C-Ex or HA32D-Ex UPS Auxiliary Cabinet, or an HA33D-Ex UPS CSA Cabinet with an isolation/step-down transformer to step down the 600 Vac to 208 Vac for use with the HA32Ax UPS. 1.5.3 UPS Distribution Cabinet The HA32J/K UPS Distribution Cabinet provides the means for distributing power from the HA32A UPS system to the user 's intended equipment (see Chapter 6). The UPS Distribution Cabinet is furnished in an enclosure matching the other HA3000 series UPS equipment. The UPS Distribution Cabinet attaches to the right side of the HA32A UPS enclosure, the right side of the UPS Auxiliary Cabinet, or the right side of the UPS CSA Cabinet. 1.5.4 Remote Status Panel The Remote Status Panel option may be deskmounted or wallmounted, and uses the same SS&CP as the HA32A UPS (see Figure 1-4). The Remote Status Panel includes the mimic panel to indicate the flow of power; an LCD for display of status, alarms, and parameters measured; and keys for requesting voltage and current data. An interface cable between the Remote Status Panel and the HA32A UPS is included. The HA320-AA model has a 150-foot cable, and the HA320-AB model has a 300-foot cable. 1.5.5 Remote Alarm Panel The HA320-A3 Remote Alarm Panel consists of a wallmounted panel with four indicating LEDs: · A green UPS On Line LED · A yellow Load On Bypass LED · A yellow UPS On Battery LED · A red Summary Alarm LED The Remote Alarm Panel also includes: · An Alarm Reset push button, to reset the latching alarm · An Audible Alarm (horn), for alarm annunciation · An Audio Reset push button, to reset the Audible Alarm When an alarm occurs, the appropriate LED will stay on (latch) even if the alarm is corrected. This feature allows the operator to verify the occurance of the alarm. Once the alarm has been corrected, the operator can silence the Audible Alarm by pressing the Audio Reset push button, and can reset the latching LEDs by pressing the Alarm Reset push button. HA3000 SERIES UPS INTRODUCTION 1-9 1.5.6 DC Ground Fault Detector The HA320-C2 DC Ground Fault Detector is used to detect current flowing from the battery terminals to ground. When a dc ground fault is detected, The UPS main ac input (MAINS1) circuit breaker (Q1) trips, shutting off the rectifier/battery charger, and initiates On Battery operation, which prevents any cascading failures. This fault is indicated by an "ENVIRONMENTAL FAULT" message on the UPS LCD display. The DC Ground Fault Detector is located inside the UPS Battery Cabinet. 1.5.7 Smoke Detector The HA320-B1 Smoke Detector is used to detect the presence of smoke within the UPS Battery Cabinet. When smoke is detected inside the UPS Battery Cabinet, an "ENVIRONMENTAL FAULT" message is displayed on the UPS LED display. The Smoke Detector is located inside the UPS Battery Cabinet. 1.5.8 Remote Emergency Power Off (REPO) The Remote Emergency Power Off (REPO) option is a wallmounted push button. The REPO feature performs the same function as the EPO (see Section 2.2) but from a remote location. 2 HA32A UPS OPERATION ------------------------------------------------------------ 2.1 GENERAL This chapter describes the HA32A system status and control panel (SS&CP), including programmable controls, electromechanical controls, the UPS monitor and available menus, operating modes, and alarm conditions. 2.2 SYSTEM STATUS AND CONTROL PANEL (SS&CP) The SS&CP is located on the upper right portion of the HA32A UPS enclosure.

HA32A UPS OPERATION 2-29 2.5 OPERATING MODES The HA32A UPS has both automatic and manual operating modes. These modes of operation are described in more detail in the following sections. 2.5.1 Automatic Operating Sequences The four automatic operating sequences are described in the following sections. 2.5.1.1 Normal Operation Normal operation is when main ac input (MAINS1) power and bypass ac input (MAINS2) power are available and are within the prescribed tolerances. The critical load is being supplied by the inverter output, which is being supplied by the rectifier/battery charger output. The UPS Battery Cabinet is on float charge condition. The flow of power during normal operation is shown in Figure 2-5. Figure 2-5 Normal Operation Power Flow 2-30 HA32A UPS OPERATION 2.5.1.2 On Battery Operation On battery operation occurs when main ac input (MAINS1) power is lost, if the main ac input (MAINS1) power drops more than 15% below nominal value, or if the rectifier/battery charger circuit fails. The flow of power during on battery operation is shown in Figure 2-6. Figure 2-6 On Battery Operation Power Flow Battery protection time depends on the the ampere-hour capacity of the installed batteries and the power consumed by the load. The specified nominal battery protection time for the installed UPS Battery Cabinet is the minimum duration when operating at 25°C (77°F) with the inverter output under full-rated load (rated kVA @ 0.8 Power Factor lagging). The actual protection time can be greater than the specified protection time if the inverter is operating at less than full load. During a main ac input (MAINS1) power failure, operation on battery power can be extended by reducing the load (noncritical equipment). This can be monitored by using the Volts key and selecting DC VOLTAGE (Figure 2-2). The battery protection period ends when the battery voltage reaches the inverter cut-off voltage (325 Vdc). When the battery voltage is 10 Vdc above the inverter cutoff voltage, the LCD displays the message: LOW BATTERY SHUTDOWN This is a warning that the battery is approaching the end point of discharge and that the protection period has nearly expired. HA32A UPS OPERATION 2-31 2.5.1.3 Input Power Restored/Battery Charging As soon as main ac input (MAINS1) power is restored, and the voltage and frequency are within specified tolerances, the UPS returns to normal operation (see Section 2.5.1.1). If the battery reaches its end point of discharge before the main ac input (MAINS1) power is restored, the UPS inverter will shut down and must be manually restarted by following the START-UP menu in Section 2.4.1. Under normal circumstances the rectifier/battery charger immediately begins recharging the battery. Minimum battery recharge time (yielding 95% capacity) is ten times the discharge time. Example: A 5 minute discharge time will require 50 minutes of charge time to reach 95% capacity. Twenty four hours is required for full recharge. 2.5.1.4 UPS Inverter Shutdown or Major Overload In the event of a UPS inverter shutdown (either manually initiated by the user or caused by the UPS internal protective devices), the load is automatically transferred to the bypass ac input (MAINS2) power source without interruption of load power. The power flow for a UPS inverter shutdown or major overload is shown in Figure 2-7. Figure 2-7 UPS Inverter Shutdown or Major Overload Power Flow 2-32 HA32A UPS OPERATION In the event of a major overload (inrush condition) on the output of the UPS inverter, an immediate transfer of the load to the bypass ac input (MAINS2) power source takes place. The load is automatically returned to the UPS inverter output without interruption when the inrush condition is over. This operating mode allows startup of load devices demanding short-term, high inrush currents, provided that the UPS inverter is synchronized to the bypass ac input (MAINS2) power source. The UPS inverter output is synchronized to the bypass ac input (MAINS2) power source when the following conditions are satisfied. · Bypass voltage must be within ±10% of nominal value · Bypass frequency must be within the frequency window selected (±0.25, ±0.5, ±0.75, or ±1.0 Hz) · Bypass phase must be within 3° of the UPS inverter output NOTE OUT OF SYNCHRONIZATION messages will be displayed on the LCD as minor alarms. If an overload condition occurs and the UPS inverter output is not synchronized to the bypass ac input (MAINS2) power source, the UPS inverter will limit the output current at 150% of its full-load current rating for 0.2 seconds before shutting down and forcing an interrupted transfer of the load to the bypass ac input (MAINS2) power source. The UPS inverter provides full output voltage at 125% overload for 10 minutes or at 150% overload for 1 minute. If a 125% overload still exists after 10 minutes or a 150% overload still exists after 1 minute, the static switch will transfer the load to the bypass ac input (MAINS2) power source. If the the 125% overload still exists after 10 minutes on bypass or the 150% overload still exists after 1 minute on bypass, the static switch will shut off and the load will be dropped. 2.5.2 Manual Operating Sequences The six manual operating sequences are described in the following sections. 2.5.2.1 Rectifier/Battery Charger Start or Stop This sequence is used to stop the rectifier/battery charger to force the UPS to on battery operation, and to start the rectifier/battery charger to return the UPS from on battery operation to normal operation. These operational sequences can be initiated by following the instructions in the Main Menu, item COMMANDS (see Section 2.4.6.1). 2.5.2.2 UPS Inverter Start or Stop This sequence is used to stop the inverter to force the static switch to transfer the load to the bypass ac input (MAINS2) power source, and to start the inverter to return the UPS from bypass to normal operation. These operational sequences can be initiated by following the instructions in the Main Menu, item INVERTER ON/OFF (see Section 2.4.2). HA32A UPS OPERATION 2-33 2.5.2.3 UPS Manual Bypass This sequence is used to manually transfer the load to the bypass ac input (MAINS2) power source to bypass the UPS circuits. This sequence should be initiated when problems with the rectifier/battery charger or static switch present the possibility of dropping power to the critical load. This operational sequence can be initiated by following the instructions in the Main Menu, item BYPASS PROCEDURE (see Section 2.4.5). The power flow for the UPS manual bypass is shown in Figure 2-8. WARNINGS The EPO keys and the REPO push button will NOT remove output power from the UPS when the UPS is in manual bypass. There are still high voltages present in the HA32A UPS cabinet with the UPS in manual bypass. DO NOT open the left door or remove any covers or protective panels when in manual bypass. Figure 2-8 UPS Manual Bypass Power Flow 2.5.2.4 Returning the UPS to Normal Operation from Manual Bypass To return to normal operation from manual bypass, press the Menu key and scroll down the menus available with the Scroll Down key until item number 5, BYPASS PROCEDURE, is displayed on the LCD. Press the 5 key and then select submenu number 2, RETURN TO UPS, by pressing the 2 key. Follow the instructions displayed on the LCD to transfer the UPS back on-line. 2-34 HA32A UPS OPERATION 2.6 ALARMS There are two types of alarms in the HA32A UPS; minor and major alarms. The following sections describe the minor and major alarms and contain tables listing the alarms and what they indicate. There are no customer serviceable parts in the UPS equipment. For all repairs, call 1-800-272-2001 or your Digital Services office. 2.6.1 Minor Alarms Minor alarms are those that occur during normal operation but do not interfere with the normal operation of the UPS. These alarms should be corrected as soon as possible.

Figure 3-1 depicts the HA32B UPS Battery Cabinet. Figure 3-1 HA32B UPS Battery Cabinet 3-1 3-2 HA32B UPS BATTERY CABINET 3.1.1 General Description Each HA32A UPS requires a separate HA32B UPS Battery Cabinet(s), which contains batteries having sufficient ampere-hour (A h) capacity to support the UPS and its intended load for the protection time specified. The UPS Battery Cabinets are supplied in compact enclosures similar to the enclosures used for the HA32A UPS. They provide a convenient means of reducing expensive floor space requirements for uninterruptible power systems installations when compared with open-rack battery configurations. In addition to minimizing floor space requirements, installation time is drastically reduced. The HA32B UPS Battery Cabinet features sealed, maintenance-free, recombination type batteries. The batteries are maintenance-free because they do not require that the electrolyte level or the density of the electrolyte be checked periodically. The UPS Battery Cabinets do require that the interior of the assembly, including the exterior surfaces of the individual batteries, be kept clear of all foreign matter including dust. The integrity of the individual battery connections must be verified on a yearly basis. The batteries are sealed and do not release gas under normal operating conditions. They can be used practically anywhere. They operate on the principle of gas recombination within the battery itself. The batteries have a safe, low-pressure venting system that releases excess gas should the internal gas pressure rise to a level above the normal rate, then seals automatically when internal pressure returns to normal. The batteries are designed for maximum life when operated within an ambient temperature range of 20° to 25°C (68° to 77°F). Operating in a warmer environment increases the ampere-hour capacity of the battery, which extends the protection period in the short run. Operating the batteries at warmer temperatures, however, reduces expected battery life. Conversely, operating in a cooler environment decreases the ampere-hour capacity of the battery, reducing the protection period in the short run, but extending expected battery life. The HA32B UPS Battery Cabinet provides ready access to the internal batteries, which are rack mounted on easily accessible pull-out rack assemblies. The 31.5-inch cabinet has a single pull-out rack assembly on which the batteries are mounted. All 45-inch and 52-inch wide cabinets have two pull-out rack assemblies on which the batteries are mounted. 3.1.2 Specifications The UPS Battery Cabinet is designed to accommodate multiple combinations of batteries in order to match the requirements of a particular load. A basic 12-volt battery, made up of six series-connected lead-calcium cells, forms the basic building block for all UPS Battery Cabinets. The batteries are series-connected to form a "string" of batteries that provides the required dc voltage level to operate with the HA32A UPS. 3.1.3 Protection Period Each UPS Battery Cabinet is designed to provide a specified backup or protection time for the equipment with which it is designed to operate. This protection time is based on the equipment operating at rated load (full kVA rating at 0.8 power factor lagging) in an ambient temperature of 25°C (77°F). Operating at a warmer temperature extends this protection period but reduces expected battery life. Operating at a cooler temperature shortens this protection period but increases expected battery life. HA32B UPS BATTERY CABINET 3-3 3.2 OPERATION This section describes standard operating procedures, including battery disconnect circuit breaker QF1 operation, normal operation, and emergency power off (EPO) operation. The UPS Battery Cabinet should be kept in a charged condition for optimum performance over the extended life of the batteries. A discharged UPS Battery Cabinet should be recharged as soon as possible and should not be allowed to remain in a discharged state for an extended period of time (battery life could be significantly reduced). If the equipment that the UPS Battery Cabinet is intended to protect is taken out of service for an extended period of time, the UPS Battery Cabinet should be left connected to the operating rectifier/battery charger in each system to maintain the batteries in an optimum condition. 3.2.1 Battery Disconnect Circuit Breaker QF1 QF1 allows you to manually connect or disconnect the UPS Battery Cabinet from its intended load, the HA32A UPS. QF1 also provides overload protection in the event that the intended load demands more current than the UPS Battery Cabinet can safely furnish. Each UPS Battery Cabinet has a battery disconnect circuit breaker QF1, therefore, if the system has two UPS Battery Cabinets, there are two QF1s. 3.2.1.1 Normal Operation Under normal operation, QF1 acts as an on/off switch to connect or disconnect the UPS Battery Cabinet from the HA32A UPS. 3.2.1.2 QF1 Trip The reasons that circuit breaker QF1 might trip include: · Overload · Low battery voltage · Emergency power off (EPO) command from the HA32A UPS 3.2.1.3 QF1 Reset After correcting the condition that caused QF1 to trip, manually place QF1 to the off position, then place QF1 to the on position to reset it. 3.2.2 Emergency Power Off (EPO) The UPS Battery Cabinet disconnect circuit breaker QF1 is connected to the UPS emergency power off system. The two EPO keys, located on the HA32A UPS SS&CP, are pushed simultaneously to initiate an emergency power off signal. When the UPS Battery Cabinet disconnect circuit breaker QF1 receives this signal, QF1 turns off and the UPS Battery Cabinet is disconnected from the UPS. The EPO keys should only be used for emergency situations. DO NOT use the EPO keys for a normal shutdown sequence. 4 HA32C/D/E UPS AUXILIARY CABINET ------------------------------------------------------------ 4.1 INTRODUCTION This section describes the HA32C/D/E UPS Auxiliary Cabinets, features, and options. 4.1.1 General Description The HA32C/D/E UPS Auxiliary Cabinet is available in three different configurations for use with the HA32A UPS. The configurations are: 1. Isolation Transformer (HA32D-xx) The isolation transformer can be configured in one of three ways: a. UPS Input Isolation Transformer: The isolation transformer provides complete electrical isolation between the ac input source and the input of the UPS (rectifier/battery charger and battery). See Figure 4-1. Figure 4-1 UPS Input Isolation Transformer Configuration 4-1 4-2 HA32C/D/E UPS AUXILIARY CABINET b. Bypass Input Isolation Transformer: The isolation transformer provides complete electrical isolation between the ac input source and the critical load when the UPS is operated on static bypass or manual bypass. See Figure 4-2. Figure 4-2 Bypass Input Isolation Transformer Configuration c. UPS Input and Bypass Input Isolation Transformer: The isolation transformer can be connected to provide electrical isolation for both the main ac input (MAINS1) and the bypass ac input (MAINS2) to the UPS. See Figure 4-3. NOTE To connect the isolation transformer described in configuration "c" above, the UPS main ac input (MAINS1) and bypass ac input (MAINS2) voltages must be from the same source. See Figure 4-3. Figure 4-3 UPS Input and Bypass Input Isolation Transformer Configuration HA32C/D/E UPS AUXILIARY CABINET 4-3 2. UPS Input Harmonic Current Filter (HA32E-Px) The input harmonic current filter limits the amount of current distortion fed back onto the ac input source to less than 10% when the HA32A UPS is operating at full load. 3. Isolation Transformer and UPS Input Harmonic Current Filter (HA32C-xx) The UPS Auxiliary Cabinet can be supplied with both of these UPS options installed within the single Auxiliary Cabinet enclosure. NOTE The HA32C-Ex or HA32D-Ex UPS Auxiliary Cabinet models or the HA33D-Ex UPS CSA Cabinet are required for use with the HA32A-Ax UPS for systems with a 600 Vac input. These UPS Auxiliary Cabinets and the UPS CSA Cabinets house the isolation/step-down transformer. The transformer secondary voltage is 208 Vac and the transformer supplies both the UPS main ac input (MAINS1) and the bypass ac input (MAINS2). See Figure 4-3. 4.1.2 Input Circuit Breaker (CB1) Each HA32C and HA32D UPS Auxiliary Cabinet is provided with an input circuit breaker (CB1). This breaker is located on the ac input source to the UPS Auxiliary Cabinet. It provides overcurrent protection and mechanical isolation for maintenance purposes. 4-4 HA32C/D/E UPS AUXILIARY CABINET 4.2 OPERATION This section describes standard operating procedures, including operation of the input circuit breaker (CB1), the input isolation transformer, and the input harmonic current filter. 4.2.1 Input Circuit Breaker (CB1) CB1 allows you to manually connect or disconnect the input isolation transformer located inside the HA32C or HA32D UPS Auxiliary Cabinet. CB1 also provides extra protection against overload conditions. Overload conditions cause the input circuit breaker CB1 to trip. The position of CB1 is monitored by the HA32A UPS. If CB1 trips, the LCD on the HA32A UPS will display: "ENVIRONMENTAL FAULT". Check the position of circuit breaker CB1. If it is in the center position (trip condition), reset the circuit breaker by pushing down on the handle, then close the circuit breaker by pulling up on the handle. When circuit breaker CB1 is opened or tripped, the rectifier/battery charger in the HA32A UPS will shut down, and the inverter will operate on battery if the UPS Auxiliary Cabinet is configured as shown in Figure 4-1 or Figure 4-3. If the UPS Auxiliary Cabinet is configured as shown in Figure 4-2, the HA32A UPS will remain on-line, but additional alarms will be generated. 4.2.2 Input Isolation Transformer The input isolation transformer is protected against thermal overload and is continuously monitored by the HA32A UPS. Should the input isolation transformer overheat, the rectifier/battery charger will shut down and the inverter will operate on battery. The LCD on the HA32A UPS will display: "ENVIRONMENTAL FAULT". 4.2.3 Input Harmonic Current Filter The input harmonic current filter is protected by three (3) fuses: F1, F2, and F3. Should one or more of these fuses open, the LCD on the HA32A UPS will display: "ENVIRONMENTAL FAULT". The failure of these fuses will not cause the HA32A UPS rectifier/battery charger to shut down. 5 HA33D/F UPS CSA CABINET ------------------------------------------------------------ 5.1 INTRODUCTION This section describes the HA33D/F UPS CSA Cabinets, features, and options. 5.1.1 General Description The HA33D/F UPS CSA Cabinet is available in two different configurations for use with the HA32A UPS. The configurations are: 1. CSA Assembly Only (HA33F-Px) A UPS CSA Cabinet with only a CSA assembly is used when 208 Vac utility power is available for the HA32A UPS. The UPS CSA Cabinet provides power from the ac input source for both the main ac input (MAINS1) and the bypass ac input (MAINS2) in the UPS. The CSA assembly contains a mechanical contactor to provide feedback protection during a utility power outage if there is a shorted SCR in the static switch. See Figure 5-1. Figure 5-1 CSA Assembly Only Configuration 5-1 5-2 HA33D/F UPS CSA CABINET 2. CSA Assembly and Isolation/Step-down Transformer Configuration (HA33D-Ex) This configuration of the UPS CSA Cabinet is used when 600 Vac utility power is available for the HA32A UPS. The CSA assembly and the isolation/step-down transformer are both installed within the single UPS CSA Cabinet enclosure. NOTE The HA32C-Ex or HA32D-Ex UPS Auxiliary Cabinet models, or the HA33D-Ex UPS CSA Cabinet are required for use with the HA32A-Ax UPS for systems with a 600 Vac input. These UPS Auxiliary Cabinets and the UPS CSA Cabinets house the isolation/step-down transformer. The transformer secondary voltage is 208 Vac, and the transformer supplies both the UPS main ac input (MAINS1) and the bypass ac input (MAINS2). See Figure 5-2. The isolation/step-down transformer provides a step-down of 600 Vac to 208 Vac and electrical isolation for both the main ac input (MAINS1) and the bypass ac input (MAINS2) to the UPS. See Figure 5-2. Figure 5-2 CSA Assembly and Isolation/Step-Down Transformer Configuration 5.1.2 Contactor Control Switch (SW1) Each HA33D and HA33F UPS CSA Cabinet contains a contactor control switch (SW1). This switch is closed to allow the ac input source to energize the mechanical contactor which provides power to the bypass ac input (MAINS2) of the UPS. Switch SW1 is used for maintenance purposes to electrically isolate the contactor control fuses (F4, F5, and F6) and the coils of contactors K2 and K4. 5.1.3 Input Circuit Breaker (CB1) The HA33D UPS CSA Cabinets are provided with an input circuit breaker (CB1). This breaker is located on the ac input source to the UPS CSA Cabinet. It provides overcurrent protection and mechanical isolation for maintenance purposes. HA33D/F UPS CSA CABINET 5-3 5.2 OPERATION This section describes standard operating procedures, including operation of the input circuit breaker (CB1), the contactor control switch (SW1), and the input isolation/step- down transformer. During normal operation, the UPS inverter supplies power to the load while the static switch is off and in standby mode. The contactor control switch SW1 in the UPS CSA Cabinet is manually closed to allow the ac input source to energize contactor coils K2 and K4, causing their contacts to close. This allows the ac input source to be gated to the bypass ac input (MAINS2) of the UPS. If the ac input source power fails, the contactor coils of K2 and K4 will deenergize causing their contacts to open. When the contacts of contactor K2 open, a mechanical isolation between the bypass ac input (MAINS2) in the UPS and the ac input source will exist. This will prevent the flow of power from the inverter output to the ac input source in the event of a static switch SCR failure (short circuit). 5.2.1 Input Circuit Breaker (CB1) CB1 allows you to manually connect or disconnect the input isolation/step-down transformer located inside the HA33D UPS CSA Cabinet. CB1 also provides extra protection against overload conditions. Overload conditions cause the input circuit breaker CB1 to trip. The position of CB1 is monitored by the HA32A UPS. If CB1 trips, the LCD on the HA32A UPS will display: "ENVIRONMENTAL FAULT". Check the position of circuit breaker CB1. If it is in the center position (trip condition), reset the circuit breaker by pushing down on the handle, then close the circuit breaker by pulling up on the handle. When circuit breaker CB1 is opened or tripped, the rectifier/battery charger in the HA32A UPS will shut down, and the inverter will operate on battery. 5.2.2 Contactor Control Switch (SW1) The contactor control switch SW1 is closed during normal operation. This allows the ac input source to energize the K4 and K2 contactor coils and gate the ac input source to the bypass ac input (MAINS2) of the UPS. The contactor control circuit is protected by three 5 Amp fuses: F4, F5, and F6. The failure of one or more of these fuses will deenergize the K2 contactor and disconnect the ac input source from the bypass ac input (MAINS2) of the UPS, but will not cause the HA32A UPS rectifier/battery charger to shut down. Contactor control switch SW1 is used for maintenance purposes to electrically isolate the contactor control fuses (F4, F5, and F6) and the coils of contactors K2 and K4. 5.2.3 Input Isolation/Step-Down Transformer The input isolation/step-down transformer is protected against thermal overload and is continuously monitored by the HA32A UPS. Should the input isolation/step-down transformer overheat, the rectifier/battery charger will shut down and the inverter will operate on battery. The LCD on the HA32A UPS will display: "ENVIRONMENTAL FAULT". 6 HA32J/K UPS DISTRIBUTION CABINET ------------------------------------------------------------ 6.1 INTRODUCTION This chapter introduces the HA32J/K UPS Distribution Cabinet. The equipment is described, followed by a description of available options. Figure 6-1 depicts the HA32J/K UPS Distribution Cabinet. Figure 6-1 HA32J/K UPS Distribution Cabinet 6-1 6-2 HA32J/K UPS DISTRIBUTION CABINET 6.1.1 System Description The HA32J/K UPS Distribution Cabinet provides the means to distribute power from the HA32A UPS to the user 's intended equipment. The HA32J/K UPS Distribution Cabinet is furnished in an enclosure matching the other HA3000 series equipment. The HA32J/K is designed to attach to the right side of the HA32A UPS, or to either the right side of the HA32C/D/E UPS Auxiliary Cabinet or the HA33D/F UPS CSA Cabinet if these options are purchased. The HA32J is furnished with one 42-pole position, 225-ampere rated panelboard, and one 225-ampere rated branch circuit breaker. The HA32K is furnished with two 42-pole position, 225-ampere rated panelboards, and two 225-ampere rated branch circuit breakers. A single-line diagram of the HA32A UPS and the HA32J/K UPS Distribution Cabinet is shown in Figure 6-2. Figure 6-2 HA32J/K and HA32A Single-Line Diagram HA32J/K UPS DISTRIBUTION CABINET 6-3 6.2 OPERATION This section describes the operation of circuit breaker(s) CB1, CB2, and CB3, and the operation of the output circuit breaker(s). Figure 6-3 shows the location of the circuit breakers. Figure 6-3 HA32J/K Circuit Breaker Locations 6.2.1 Circuit Breaker(s) CB1, CB2, and CB3 Circuit breaker CB1 is present in a UPS Distribution Cabinet with an isolation transformer. All power to a UPS Distribution Cabinet with an isolation transformer passes through CB1. Circuit breakers CB2 and CB3 allow you to manually connect or disconnect the HA32J/K UPS Distribution Cabinet panelboards to the output of the HA32A UPS. They also provide extra protection against overload conditions. Overload conditions cause the branch circuit breaker(s) to trip. 6-4 HA32J/K UPS DISTRIBUTION CABINET The branch circuit breaker(s) handle has three positions: 1. OFF or circuit breaker open = handle in the bottom position 2. TRIP or circuit breaker open = handle in the middle position 3. ON or circuit breaker closed = handle in the top position To reset the branch circuit breaker after it has tripped, push the handle down to the OFF position, then move the handle up to the ON position. 6.2.2 Output Circuit Breaker(s) The output circuit breaker(s) allow you to manually connect or disconnect each load connected to the output of the HA32J/K UPS Distribution Cabinet without affecting the other loads. The output circuit breaker(s) protects the individual loads against overload conditions. Overload conditions cause the output circuit breaker(s) to trip. The output circuit breaker(s) handle has three positions: 1. OFF or circuit breaker open 2. TRIP or circuit breaker open 3. ON or circuit breaker closed To reset an output circuit breaker after it has tripped, push the handle to the OFF position, then move the handle to the ON position.
