Service personnel should familiarize themselves with symbols marked on the UPS:

This symbol indicates a protective grounding terminal (a terminal which must be connected to earth ground prior to making any other connection to the equipment).

This symbol indicates a terminal to which or from which a direct current or voltage may be applied or supplied.

This symbol indicates the word phase.

UPS Location Warnings

• Install the UPS indoors, away from heat, direct sunlight, dust, and excess moisture or other conductive contaminants.

• Install the UPS away from flammable liquids and gases. Do not let the unit come in contact with water or other liquids.

• Install the UPS in a structurally sound area. Your UPS is extremely heavy. Flooring must be able to support the weight of all UPS modules. Take care when moving and lifting the unit.

• Only operate the UPS at indoor temperatures between 32° F and 104° F (between 0° C and 40° C) with humidity within a range of 0 to 95% (non-condensing). For best results, keep indoor temperatures between 62° F and 84° F (between 17° C and 29° C).

• Leave adequate space around all sides of the UPS for proper ventilation: at least 40 inches (100 cm) from front panel and 20 inches (50 cm) from top, rear and side panels. Do not cover ventilation openings on the unit.

• Do not install the UPS near magnetic storage media, as this may result in data corruption.

UPS Connection Warnings

• The power supply for this unit must be three-phase rated in accordance with the equipment nameplate. It also must be suitably grounded according to all applicable local electrical wiring regulations.

• The UPS must be isolated prior to any connection or maintenance. A readily-accessible disconnect device must be incorporated into the wiring following all local electrical codes. The disconnect device must be four-pole and must be able to disconnect all line conductors and the neutral conductor.

• Due to high leakage current, a ground connection is essential.

Equipment Connection Warnings

• Do not use Tripp Lite UPS Systems in life support applications in which a malfunction or failure of a Tripp Lite UPS System could cause failure or significantly alter the performance of a life support device.

• The UPS is designed to power computer equipment. Do not use the UPS with purely inductive or capacitive loads.

• The UPS System includes its own energy source (external battery). The output terminals may be live even when the UPS is not connected to an AC supply.

Battery Warnings

• The UPS does not require routine maintenance. Do not open the UPS for any reason. There are no user-serviceable parts inside.

• Risk of electrocution is possible when battery module is connected to the power module. Qualified service personnel must disconnect the batteries prior to maintenance.

• Because the batteries present a risk of electrical shock and burn from high short-circuit current, batteries should be changed only by trained service personnel observing proper precautions. Consult your battery module manual before proceeding. Remove watches, rings, and other metal objects. Use tools with insulated handles. Wear rubber gloves and boots. Do not lay tools or metal parts on top of the batteries. Do not short or bridge the battery terminals with any object. Disconnect the charging source prior to connecting or disconnecting battery terminals. Determine if the batteries are inadvertently grounded. If inadvertently grounded, remove the source of the ground. Contact with any part of a grounded battery can result in electrical shock. The likelihood of such shock will be reduced if such grounds are removed during installation and maintenance.

• Do not dispose of the batteries in a fire. The UPS batteries are recyclable. Refer to local codes for disposal requirements.

Installation

Follow all warnings listed in the Safety section prior to installation. The following checklist provides a general guide rather than a complete outline of procedures.

Installation Checklist

K The floor area where the UPS will be installed has enough supporting strength. See Floor Weight Loading Table on the 3-Phase

UPS Specifications Addendum—50kVA & Above.

K The entrances and hallways to the facility provide enough room for UPS transportation.

K The room where the UPS will be installed has enough clearance around the UPS modules to allow adequate ventilation and access for operation

and maintenance.

K The facility's air conditioning can maintain ideal temperature and humidity levels.

K Noise abating devices are installed (if desired).

K Electrical wiring is clearly marked (for polarity and phase) and checked for compliance with local electrical codes.

K The input power source has been switched off prior to hardwire connection.

K The room where the UPS will be installed includes floor, ceiling and walls made of flameproof materials. The room includes a fire

extinguisher. The room is secure from access by unauthorized personnel.

K All personnel are sufficiently trained for normal and emergency operations.

K During installation, the UPS input neutral is solidly connected to the utility power neutral.

Parallel Wiring Diagrams

In a parallel connection, up to eight UPS Systems are connected to a single load. A parallel connection provides fail-safe redundancy, assuring that the load is constantly supported even if one or more UPS Systems fail or are taken off-line for maintenance. Within a parallel architecture, there is a “single loop” connection option (where only one input source is used) and a “double loop” connection option (where two input sources are used). Note: in both connection options the total length of all cables (input, output and reserve) must be the same for each UPS Power Module to prevent load inequality.

All Models

• Single Loop Connection (one input source used) • Double Loop Connection (two input sources used)

Electrical Connection

Follow all warnings listed in the Safety section prior to hardwire terminal connection. The following checklist provides a general guide rather

than a complete outline of procedures.

Connection Checklist

K Turn off input power prior to electrical connection.

K Check the input, output and battery cables for proper amplitude, phase and polarization.

K Connect ground wire(s) between UPS power module(s) and battery module(s).

K If the input and output power of the UPS is a Y connection, then note that the Neutral wire and Ground wire are not connected within the UPS

power module.

K If the input power system has a floating voltage between Neutral and Ground, and if 0 volts is desired between Neutral and Ground within the

UPS power module, Tripp Lite recommends the following: add a user-supplied isolation transformer to the input of the UPS, and connect the Neutral wire and Ground wire inside the UPS power module.

K If installing multiple UPS modules in parallel, ensure input and output cables are the same length for each module.

3-Phase UPS Specifications Addendum—50kVA & Above.

LOAD

Single UPS Operation

The diagrams and procedures in this section apply to a single UPS Power Module connected to a single equipment load. Note: all diagrams assume the presence of two separate AC sources supplying two separate inputs: a mains source supplying rectifier input and a reserve source supplying reserve input. If your application only allows a single mains AC source, this source will supply both rectifier and reserve input.

• Operational Modes • Shutdown Procedure

• Start-Up Procedure • Manual Maintenance Bypass Procedure

Operational Modes

Normal Mode

In this mode, the power module continuously converts AC input power into DC power (to recharge the batteries and supply the inverter). The inverter, in turn, transforms DC power into clean, stable AC output power for the connected equipment load.

Back-Up Mode

In this mode, utility AC input power has failed. Since the UPS System operates continuously on-line, connected battery modules instantly (with zero transfer time) supply DC power to the inverter. The inverter, in turn, transforms DC power into clean, stable AC output power for the connected equipment load.

8 8

Single UPS Operation

(continued)

Reserve AC Input Supply Mode

In this mode, the power module's inverter has encountered one of several abnormal operating conditions including overtemperature, continual overload, shorted output or depleted battery power. The power module automatically shuts down the inverter to prevent damage. In order to bypass the inverter, the power module automatically transfers to a reserve AC input source to support the connected equipment load. (Note: since the power module's inverter is bypassed in this mode, the UPS will not be able to switch to Back-Up Mode in the event of a power failure.) After the power module detects that abnormal operating conditions are over, it automatically reactivates the inverter and switches back to the mains AC input source to support the connected equipment load.

Maintenance Bypass Mode

In this mode, the Manual Maintenance Procedure (On Bypass) has been performed in order to pass-through filtered AC input power (from a reserve AC input source) to connected equipment loads while allowing maintenance on the UPS power module. (Note: since the power module's inverter is bypassed in this mode, the UPS will not be able to switch to Back-Up Mode in the event of a power failure.) After the Manual Maintenance Procedure (Off Bypass) has been performed, the power module automatically reactivates the inverter and switches back to the mains AC input source to support the connected equipment load.

Start-Up Procedure

This procedure supplies power to and starts up the UPS. Please check the following items before UPS start-up:

K Ensure that all electrical connections to the power module and battery module(s) have been completed.

K Check that all circuit breakers and isolators are in the off position and battery fuse(s) have been removed.

K Ensure that the neutral line and grounding are at the same voltage level.

K Apply power to the AC input cables, and check that input voltage, frequency and phase sequence are within the specifications of the UPS and

the equipment load.

K Check to ensure auxiliary power and fan power (N) fuse isolators are closed.

Single UPS Operation

(continued)

After following all warnings listed in the Safety section and precautions listed above, start-up UPS according to the following procedure:

Step 1. Turn on (close) the “RESERVE INPUT” Breaker. The LCD Screen will display “Bypass Mode”. Step 2. Turn on (close) the “RECTIFIER INPUT” Breaker and wait about 30 seconds. The DC BUS voltage will be built up to about 393V DC. Step 3. Locate the external fuse block(s) on the battery module(s) and turn on (close) the fuses. Step 4. Simultaneously press the “ON” and “ ” Buttons and hold for 3 seconds. The inverter will turn on and voltage will build for about 30

seconds. The load will be transferred to the inverter. The LCD Screen will display “Normal Mode”.

Step 5. Measure the voltage on the UPS Output Breaker to determine if it is normal or abnormal. If the output voltage is normal, close the Output

Breaker to supply the load. After approximately 30 seconds, the UPS will automatically execute a battery test.

Shutdown Procedure

This procedure removes power from and shuts down the UPS.

Step 1. Turn off (open) the “UPS OUTPUT” Breaker. Step 2. Simultaneously press the “OFF” and “ ” Buttons and hold for 3 seconds. When the reserve power has returned to normal (where its

voltage and frequency are within the set range), the power module's inverter will turn off immediately. Support of the equipment load will be transferred to reserve power. The LCD Screen will display “Bypass Mode”.

Step 3. Locate the external fuse block(s) on the battery module(s) and turn off (open) the fuses. Step 4. Turn off (open) the “RECTIFIER INPUT” Breaker. Step 5. Wait approximately 5 minutes for the DC capacity to discharge. Press the “ON” and “OFF” Buttons to test the inverter for adequate

discharge of DC capacity, and then simultaneously press the “OFF” and “ ” Buttons to turn off the inverter. Confirm that BUS voltage is safe.

Step 6. Turn off (open) the “RESERVE INPUT” Breaker.

Manual Maintenance Bypass Procedure

This procedure allows for routine maintenance by qualified service personnel. Tripp Lite recommends a routine maintenance inspection every six months. Note: since the power module's inverter is bypassed during this procedure, the UPS will not be able to switch to Back-Up Mode and support connected equipment in the event of a power failure.

Manual Maintenance Procedure (ON Bypass) Step 1. Simultaneously press the “OFF” and “ ” Buttons and hold for 3 seconds. When the reserve power has returned to normal (where its voltage

and frequency are within the set range), the power module's inverter will turn off immediately. Support of the equipment load will be transferred to reserve power. The LCD Screen will display “Bypass Mode”.

Step 2. Locate the external fuse block(s) on the battery module(s) and turn off (open) the fuses. Step 3. Turn off (open) the “RECTIFIER INPUT” Breaker. Step 4. Wait approximately 5 minutes for the DC capacity to discharge. Press the “ON” and “OFF” Buttons to test the inverter for adequate

discharge of DC capacity, and then simultaneously press the “OFF” and “ ” Buttons to turn off the inverter. Confirm that BUS voltage is safe.

Step 5. Turn on (close) the “MANUAL BYPASS” Breaker. Support of the equipment load will transfer to manual bypass. The LCD Screen will

display “Manual Bypass”.

Step 6. Turn off (open) the “UPS OUTPUT” Breaker, the “RESERVE INPUT” Breaker and the auxiliary power (+) and fan power (N) fuse

isolators. The LCD Screen will go dark.

Note: When the UPS is in Maintenance Bypass Mode, no high voltages will be present within the UPS power module except at the terminals and the “MANUAL BYPASS”Breaker.

Manual Maintenance Procedure (OFF Bypass): Step 1. Turn on (close) the “UPS OUTPUT” Breaker, the “RESERVE INPUT” Breaker and the auxiliary power (+) and fan power (N) fuse

isolators. Support of the equipment load will transfer to manual bypass. The LCD Screen will display “Manual Bypass”.

Step 2. Turn off (open) the “MANUAL BYPASS” Breaker. Support of the equipment load will transfer to reserve power. The LCD Screen will

display “Bypass Mode”.

Step 3. Turn on (close) the “RECTIFIER INPUT” breaker and wait approximately 30 seconds. The DC BUS voltage will be built up to about

393V DC.

Step 4. Locate the external fuse block(s) on the battery module(s) and turn on (close) the fuses. Step 5. Simultaneously press the “ON” and “ ” Buttons and hold for 3 seconds. The inverter will turn on and voltage will build for about 30

seconds. The load will be transferred to the inverter. The LCD Screen will display “Normal Mode”.

Multiple UPS Operation (Parallel)

The diagrams and procedures in this section apply to a parallel configuration where multiple UPS Power Modules (up to eight) are connected to a single equipment load. A parallel configuration provides fail-safe redundancy, assuring that the load is constantly supported even if one or more UPS Systems fail or are taken off-line for maintenance. Two or more UPSs operating in parallel must have the same VA capacities, output voltage and frequency. They also must be able to assume an equal share of the equipment load in order to not overload the UPSs and switch all UPSs to Reserve AC Input Supply Mode.

Operational Modes

Normal Mode

In this mode, the power modules continuously convert AC input power into DC power (to recharge their batteries and supply their inverters). Their inverters, in turn, transform DC power into clean, stable AC output power for the connected equipment load.

Multiple UPS Operation (Parallel)

(continued)

Back-Up Mode

In this mode, utility AC input power has failed. Since the UPS Systems operate continuously on-line, their connected battery modules instantly (with zero transfer time) supply DC power to their inverters. Their inverters, in turn, transform DC power into clean, stable AC output power for the connected equipment load.

Reserve AC Input Supply Mode

In this mode, the power modules' inverters have encountered one of several abnormal operating conditions including overtemperature, continual overload, shorted output or depleted battery power. The power modules automatically shut down their inverters to prevent damage. In order to bypass their inverters, the power modules automatically transfer to a reserve AC input source to support the connected equipment load. (Note: since the power modules' inverters are bypassed in this mode, the UPSs will not be able to switch to Back-Up Mode in the event of a power failure.) After the power modules detect that abnormal operating conditions are over, they automatically reactivate their inverters and switch back to the mains AC input source to support the connected equipment load.

Multiple UPS Operation (Parallel)

(continued)

Maintenance Bypass Mode

Optional Parallel Configuration (Hot Standby Redundancy and Common Battery)

Hot Standby Redundancy

In this configuration, one or more UPS power modules serve in a “hot standby” role in order to increase the availability of connected equipment by reducing the chances that a failure of one UPS will impact output power. During normal conditions, the UPS in a “hot standby” role does not support the connected equipment load; however, during a UPS failure, the UPS in a “hot standby” role automatically supports (through activation of the static switch) the connected equipment load. The output of the UPS in a “hot standby” role is connected to the reserve power input of another UPS power module. In order to reduce installation costs, users can use one UPS power module in a “hot standby” role for up to seven additional UPS power modules within a parallel configuration.

Multiple UPS Operation (Parallel)

(continued)

Common Battery

In this configuration, a single bank of battery modules is shared by multiple UPS power modules. This not only reduces installation costs, but saves floor space. Note: when using the LCD Screen to set battery charging, divide the charging task equally among all UPS power modules. For example: two UPS power modules are connected to a single bank of battery modules with a 100 amp-hour capacity. To charge the battery bank at a 12 amp charge current rate, select a 6 amp “Battery Charge Current” setting and a 50 amp-hour “Battery Capacity AH” setting individually on each of the LCD Screens of the two UPS power modules. Also note: in a Common Battery configuration, you will not be able to execute a battery test from the LCD Screen.

Start-Up Procedure

This procedure supplies power to and starts up the UPSs. Please check the following items before UPS start-up:

K Ensure that all electrical connections to all power modules and battery modules have been completed.

K Check that all circuit breakers and isolators are in the off position and battery fuse(s) have been removed.

K Ensure that the neutral line and grounding are at the same voltage level.

K Apply power to the AC input cables, and check that input voltage, frequency and phase sequence are within the specifications of the UPS and

the equipment load.

K Check to ensure auxiliary power and fan power (N) fuse isolators are closed.

K Using the LCD Display Screen on each UPS power module within the parallel configuration, set the UPS ID. Set a different ID for each power

module.

After following all warnings listed in the Safety section and precautions listed above, start-up UPSs according to the following procedure:

NOTE!

Apply each step to each UPS power module within the parallel configuration before moving on to the next step. Step 1: Install external parallel communication cables between the parallel ports on the UPS power modules to a computer. Step 2. Turn on (close) the “RESERVE INPUT” Breaker of each UPS power module. The LCD Screen on each UPS power module will display

“Bypass Mode”.

Step 3. Turn on (close) the “RECTIFIER INPUT” Breaker of each UPS power module and wait about 30 seconds. The DC BUS voltage will be

built up to about 393V DC.

Step 4. Locate the external fuse block(s) on the battery module(s) and turn on (close) the fuses. Step 5. For each UPS power module individually, simultaneously press the “ON” and “ ” Buttons and hold for 3 seconds. The inverter will turn

on and voltage will build for about 30 seconds. The load will be transferred to the inverter. The LCD Screen will display “Normal Mode”.

Step 6. Measure the voltage on the UPS “OUTPUT” Breaker of each power module to determine if it is normal or abnormal. If the output voltage

is normal, turn on (close) the “OUTPUT” Breakers of each power module to supply power to the load. After approximately 30 seconds, the UPS will automatically execute a battery test

Multiple UPS Operation (Parallel)

(continued)

Shutdown Procedure

This procedure removes power from and shuts down the UPS power modules.

WARNING!

When shutting down individual UPS power modules in a parallel configuration, the user must ensure that the UPS power modules

within the configuration that remain ON can collectively power the equipment load. If they cannot, the UPS power modules within the

parallel configuration will be overloaded and will shut down and cease powering the equipment load.

NOTE!

Apply each step to each UPS power module within the parallel configuration before moving on to the next step.

Step 1. For each UPS power module in the parallel configuration which will be shut down, simultaneously press the “OFF” and “ ” Buttons and

hold for 3 seconds. The power module's inverter will turn off; its LCD Screen will display “Output Close” and support of the equipment load will be transferred and shared equally among the other UPS power modules in the parallel configuration that have not yet been shut down. As each consecutive power module's inverter is turned off, however, a point will be reached where the power modules which have not yet been shut down will not be able to share the combined load. At this point, the remaining power modules will automatically shut down their inverters, transfer the load to reserve power and display “Bypass Mode” on their LCD Screens.

Step 2. Locate the external fuse block(s) on the battery module(s) and turn off (open) the fuses. Step 3. Turn off (open) the “RECTIFIER INPUT” Breaker and “UPS OUTPUT” Breaker of each UPS power module. Step 4. Wait approximately 5 minutes for the DC capacity to discharge. Press the “ON” and “OFF” Buttons of each UPS power module to test the

inverter for adequate discharge of DC capacity. Then, for each UPS power module in turn, simultaneously press the “OFF” and “ ” Buttons to turn off their inverter. Confirm that BUS voltage is safe.

Step 5. Turn off (open) the “RESERVE INPUT” Breaker of each UPS power module.

Manual Maintenance Bypass Procedure

This procedure allows for routine maintenance by qualified service personnel. Tripp Lite recommends a routine maintenance inspection every six months. Note: since the power modules' inverters are bypassed during this procedure, the UPSs will not be able to switch to Back-Up Mode and support connected equipment in the event of a power failure.

Manual Maintenance Procedure (ON Bypass) Step 1. For each UPS power module in the parallel configuration which will be placed on bypass, simultaneously press the “OFF” and “ ” Buttons

and hold for 3 seconds. The power module's inverter will turn off; its LCD Screen will display “Output Close” and support of the equipment load will be transferred and shared equally among the other UPS power modules in the parallel configuration that have not yet been placed on bypass. As each consecutive power module's inverter is turned off, however, a point will be reached where the power modules which have not yet been placed on bypass will not be able to share the combined load. At this point, the remaining power modules will automatically shut down their inverters, transfer the load to reserve power and display “Bypass Mode” on their LCD Screens.

Step 2. Locate the external fuse block(s) on the battery module(s) and turn off (open) the fuses. Step 3. Turn off (open) the “RECTIFIER INPUT” Breaker of each UPS power module. Step 4. Wait approximately 5 minutes for the DC capacity to discharge. Press the “ON” and “OFF” Buttons of each UPS power module to test the

Step 5. Turn on (close) the “MANUAL BYPASS” Breaker of each UPS power module. Support of the equipment load will transfer to manual

bypass. The LCD Screen of each UPS power module will display “Manual Bypass”.

Step 6. Turn off (open) the “UPS OUTPUT” Breaker, the “RESERVE INPUT” Breaker and the auxiliary power (+) and fan power (N) fuse

isolators of each UPS power module. The LCD Screens will go dark.

Note: When the UPSs are in Maintenance Bypass Mode, no high voltages will be present within the UPS power modules except at the terminals and the “MANUAL BYPASS” Breakers.

Manual Maintenance Procedure (OFF Bypass): Step 1. Turn on (close) the “UPS OUTPUT” Breaker, the “RESERVE INPUT” Breaker and the auxiliary power (+) and fan power (N) fuse

isolators of each UPS power module. Support of the equipment load will transfer to manual bypass. The LCD Screens will display “Manual Bypass”.

Step 2. Turn off (open) the “MANUAL BYPASS” Breaker of each UPS power module. Support of the equipment load will transfer to reserve

power. The LCD Screens will display “Bypass Mode”.

Step 3. Turn on (close) the “RECTIFIER INPUT” breaker of each UPS power module and wait approximately 30 seconds. Step 4. Locate the external fuse block(s) on the battery module(s) and turn on (close) the fuses. Step 5. For each UPS power module to be taken off bypass, simultaneously press the “ON” and “ ” Buttons and hold for 3 seconds. The inverter

will turn on and voltage will build for about 30 seconds. The load will be transferred to the inverter. The LCD Screens will display “Normal Mode”.

Step 6. Measure the voltage on the UPS “OUTPUT” Breaker of each power module to determine if it is normal or abnormal. If the output voltage

is normal, turn on (close) the “OUTPUT” Breakers of each power module to supply power to the load. After approximately 30 seconds, the UPS will automatically execute a battery test.
