INTRODUCTION

The Powerware 9170 uninterruptible power system (UPS) is a modularUPS that contains battery modules and power control modules (referredto as power modules). These modules plug into a rack cabinet structurecontaining additional control, communication, and display functionsthat enable integrated control of all power modules. The UPS is housedin a single cabinet, with extra battery capacity housed in auxiliarybattery cabinets.

The pluggable power modules can be removed and replaced(hot-swapped) without powering the UPS down if the UPS has sufficientredundant capacity. Battery modules may also be hot-swapped formaintenance. Power control circuitry in the cabinet senses problems inpower modules, and automatically transfers control and load to theremaining power modules.

All power modules share the load requirements equally. For example,three power modules are capable of supplying a total of 9 kVA. If a loadrequires only 4.5 kVA, each power module supplies 1.5 kVA to theoutput. If one power module is removed or for some reason fails, each ofthe two remaining power modules would supply half of the load, or2.25 kVA. In other words, redundancy exists when the load can besupplied by less than all of the installed power modules.

The UPS can be configured with up to seven power modules; its outputis limited such that an excess number of power modules allow thefailure of one or more modules without causing the UPS to lose anyfunctionality.

To permit UPS removal from the power path, while maintaining powerto the loads, an external bypass switch is required. This switch isoptional but recommended for system serviceability.

INSTALLATION SETUP

This chapter explains how to setup and install the Powerware 9170cabinets:

� Unpacking and setup, including clearances and location requirements

� Caster cart installation

� Stabilizer bracket installation (for 12-slot cabinets with non-isolatedoutput)

� Rack-mount installation

� Floor anchor kit installation

� Moving the cabinets

Equipment Clearances

All cabinet sizes require the following clearances to allow for servicingand adequate ventilation:

� From the side panels: 6� (15.2 cm)

� Top and back: 12� (30.5 cm)

� Front: 36� (91.5 cm)

If flexible conduit connects the UPS to the service input and loaddistribution panels, you may be able to gain access for servicing bymoving the UPS. If this is the case, you must still leave 12� (30.5 cm)clearance at the back and 6� (15.2 cm) at the sides of the UPS forventilation.

NOTE Do not block the ventilation holes on each side and the back of the unit.

Nine- and 12-slot external battery cabinets may be installed with basestight against the UPS cabinet base and against each other. Six-slotcabinets require 6� of separation.

Installation Setup


Location Requirements

Install the Powerware 9170 UPS as close as possible to the equipment orthe load distribution panel it will protect. If this distance is more than25 ft (7.6m), transient noise can reappear in the electrical distributionsystem.

If additional Powerware 9170 system batteries are in a separate cabinet,the external battery cabinet should be located as close as possible to thePowerware 9170 UPS. If the batteries will be further from the unit thanthe standard cables allow, contact your service representative or yourlocal distributor for assistance.

UPS Unpacking and Setup

The Powerware 9170 UPS is shipped in a carton on a shipping pallet.Power and battery modules are shipped in separate boxes on anotherpallet. Three-slot cabinets and modules are shipped on one pallet.

NOTE Verify that all Powerware 9170 UPS power modules are the proper type for theUPS cabinet: Universal (single-phase) modules have white labels; split-phase moduleshave blue labels. Do not mix blue and white modules in the same UPS cabinet.

To open the UPS carton and remove the UPS from its shipping pallet,use one of the following procedures. Also refer to the unpackinginstruction sheet (LTS-1724) packed inside the UPS shipping carton.

Three- and Six-Slot Cabinets1. Open the top of the carton by cutting the banding straps that

5. After placing the cabinet in its intended operating location, cutthe lifting straps or slip them off the cabinet base tabs.

6. If you are installing an external battery cabinet, continue to�Battery Cabinet Installation" on page 17.

If you do not have an external battery cabinet, continue to �UPSStartup" on page 49 for plug-receptacle units or to �ElectricalInstallation" on page 23 for hardwired units.

Nine- and Twelve-Slot Cabinets

NOTE The 12-slot Powerware 9170 UPS cabinet with non-isolated output is shippedwith two stabilizer brackets. These brackets must be attached to the wall or the floorbehind the UPS cabinet (see page 11).

1. Open the top of the carton by cutting the straps that hold thecover to the carton. Lift the cover off.

2. Remove the pallet ramp packed on top of the cabinet. Locatethe ramp-mounting hardware (supplied in the accessory kit)and attach the ramp to the pallet as shown in LTS-1724,accompanying the hardware.

3. Remove any packing material inside the carton. Also removecartons containing front panel bezels, electrical or mechanicalhardware, and printed material.

4. Lower the four cabinet casters (one at each corner of thecabinet base) by using a 1/2� hex-style socket wrench to turneach bolt clockwise.

5. With all casters fully extended, carefully roll the cabinet downthe ramp and to its intended operating location.

6. To stabilize the cabinet in its operating location, turn the fourcaster bolts counter-clockwise until the cabinet rests on thefloor. Place a plastic cap into each bolt access hole.

Installation Setup


NOTE If the floor is uneven and the cabinet is tilted or unstable, you may need toplace a thin steel plate under a corner. Do not use the caster bolts to level thecabinet.

7. If you are installing an external battery cabinet, continue to�Battery Cabinet Installation" on page 17.

If you do not have an external battery cabinet, continue to �UPSStartup" on page 49 for plug-receptacle units or to �ElectricalInstallation" on page 23 for hardwired units.

Caster Cart Installation

An optional caster cart (ASY-0527) is available for 3- and 6-slot cabinetsfor increased mobility of the UPS (see Figure 7).

NOTE The UPS cabinet is heavy. This procedure requires two people to lift andposition the cabinet onto the caster cart. Lift the cabinet using four lifting strapsshipped with the cabinet; do not attempt to lift the cabinet by the module shelves orother convenient edges or panels.

Caster Cart

Figure 7. Three-Slot Cabinet Being Lowered onto Caster Cart

The caster cart, shipped separately from the UPS cabinet, must be placedunder the cabinet before installing power and battery modules, andbefore plugging the UPS into the intended power outlet.

Installation Setup


The cart requires no bolts or other hardware to fasten it to the UPScabinet. It is shaped to fit securely under the cabinet, ensuring properalignment after placing the cabinet on the cart.

Four foot pads under the cart keep the cart from rolling when it is in itsintended location. Turn each threaded foot to lower it to the floor.When the foot is tight against the floor, turn the lock nut on thethreaded foot up tight against the bottom of the cart to keep the footfrom rotating.

If leveling of the UPS is required, use the foot pads to raise a side orcorner before locking them with their lock nuts.

Stabilizer Bracket Installation

The 12-slot Powerware 9170 UPS cabinet with non-isolated output isshipped with two stabilizer brackets. These brackets must be attached tothe wall or the floor behind the UPS cabinet. Under all module-loadingconditions, they act as a protective stop to prevent the cabinet fromfalling forward if it is unintentionally pushed away from the wall.

As shown in Figure 8, each bracket has holes that enable it to beattached by screws to either the wall or the floor (or both) behind theintended cabinet installation. The brackets are not attached to thecabinet base itself. Install the brackets as follows.

1. Select the location for the brackets, approximately 12�16�(30�41 cm) apart, at the floor/wall intersection behind theintended cabinet location.

2. Using the proper type of customer-supplied screws for theintended mounting surface, attach each bracket as shown inFigure 8. All screws must be driven into structural materialsuch as wall studs.

3. Roll the UPS cabinet to its intended location, positioning therear section of the cabinet base under the open ends of thestabilizer brackets, as far as the cabinet will go.

FOR U.S. INSTALLATIONS, READ THIS IMPORTANT NOTE!

This table lists the AWG and mm2 wire size for each circuit breaker size shown on the wiring diagrams. The minimumrecommended circuit breaker sizes for each model and voltage application are listed on the wiring diagrams.Conductor sizes shall be no smaller than the 75°C wire size based on the ampacities given in Table 310�16 of the NationalElectrical Code, ANSI/NFPA 70-1999, and article 220. All circuit conductors, including the neutral and equipment groundingconductors, must be the same size (ampacity) wire. Code may require a larger AWG size than shown in this table becauseof temperature, number of conductors in the conduit, or long service runs. Follow local code requirements.

Bypass Switches

Bypass switches are available in two types: Make-Before-Break (MBB)and Break-Before-Make (BBM).

An MBB switch makes a new connection before it breaks the originalconnection. For example, if you turn an MBB switch from UPS to LINE,the bypass switch connects the load to AC input power beforedisconnecting the load from UPS output power. (As noted in Figure 37on page 47, MBB switches may not be used in certain systemconfigurations.)

A BBM switch breaks the original connection before it makes a new one.If you turn a BBM switch from UPS to LINE, the switch disconnects theload from UPS output power before connecting the load to AC inputpower.

The bypass switch has four positions as described in Table 3.

NOTE In the UPS or LINE position, AC input power is still connected to the inputterminals inside the UPS.



Table 3. Bypass Switch Positions

Switch Position Description

LINE Connects the load directly to AC input power and disconnects UPS output. AC input power is stillconnected to the UPS input.

OFF Disconnects the load from the UPS output power and AC input power, as well as AC input powerto the UPS input.

UPS Connects the UPS output to the load.

SERVICE Like the LINE position, SERVICE connects the load directly to AC input power and disconnectsUPS output. However, because SERVICE also disconnects AC input from the UPS, this isthe appropriate position for UPS maintenance or repair.

To disconnect AC input power during maintenance or service, turn thebypass switch to the SERVICE position. For MBB switches, you mustpress the red button beside the switch before you can change the switchposition.

There are six bypass switch models available for the Powerware 9170UPS as specified in Table 4.

UPS Installation with an External Bypass Switch

W A R N I N GOnly qualified service personnel (such as a licensed electrician) should perform theelectrical installation. Risk of electrical shock.

C A U T I O NTo prevent electrical shock or damage to the equipment, verify that the Powerware9170 UPS is OFF before you remove the entrance panel. The circuit breaker ordisconnect switch must also be off at the AC input service panel. Also, turn OFF the ACdisconnect and bypass switches before you connect any wires to the bypass switchterminal strip.

1. Mount the bypass switch within sight of the UPS. If you do nothave a Powerware bypass switch or the fuse box or panel is outof sight, you must install a separate disconnect switch next tothe UPS.

The bypass switch should be mounted securely to a sturdysurface. You may need to turn the cabinet 90 degrees (on itsside) to enable operator access to the switch handle.

2. Remove the six screws in the bypass switch front panel andremove the panel. Remove any packing material inside thebypass switch.

Remove knockouts in the bottom of the bypass switch for ACLine Input, AC to UPS Input, AC from UPS Output, and AC tothe UPS load.

3. Remove the rear panels of the UPS (top panel on 3- or 6-slot;top 2 panels on 9- and 12-slot) as shown in Figure 21.

The entrance panel contains knockout openings for entranceand exit conduits and for conduit to an optional externalbattery cabinet. The entrance panel is located on the top 3-slotsection for 3- and 6-slot cabinets; on the second section for 9-and 12-slot cabinets as shown in Figure 21.

Wiring for optional EPO and bypass input signals passesthrough the opening at the top back of the cabinet. Wiring foran optional generator input signal must pass through a separateopening. Installing this wiring is described in Steps 11 and 12.

4. Remove the knockouts in the entrance panel for AC input andAC output wiring.



5. Install the conduit adapters. AC input and AC outputconductors must be run through separate conduits. UPS outputcircuits must be installed in dedicated conduit systems and notshared with other electrical circuits.

6. Find the terminal strip inside the bypass switch cabinet. Usingthe label on the back of the bypass switch access panel and theproper installation wiring diagram, make the terminal stripconnections and tighten all connections as specified in Table 2on page 27. Use copper wire that is the appropriate size for thecurrent draw. Figure 22 shows a sample label.

Figure 22. Bypass Switch Wiring Label

7. After installing bypass switch wiring, torque the screws holdingall input and output power conductors to the values specifiedin Table 2 on page 27.

8. If your UPS has an isolated output, find the proper outputneutral-to-ground connection in the output wiring diagramsbeginning on page 44.

At the UPS terminals, connect the neutral-to-ground(neutral-to-earth) wire to the proper terminal before making any

other connections to the UPS. The neutral-to-ground wire is agreen and yellow wire. One end of this wire is alreadyconnected to the ground (earth) UPS terminal. Groundterminations, inside the UPS rear panel, are located directlybelow the line input terminals. Figure 23 shows input andoutput wiring terminals inside the Powerware 9170 UPScabinet. Figure 36 on page 45 shows the N-G bond wireconnections.

Compression lugs (supplied in the accessorykit) may be installed on the proper terminating studs. Wiresmay also be terminated with ring terminals, which are attachedto the output terminating studs.

10. If the bypass switch is an MBB style, notice the cable routed outof the left side of the bypass switch cabinet. The red and blackpair of wires (normally open) in this cable must be connectedto terminals 3 and 4 in Steps 11 and 12. (Do not connect thewhite and black pair of wires in this cable.)

11. If any external, hardwired control signals are required, removethe rear panel on the upper section of the cabinet and locate theterminal block, as shown in Figure 24.

C A U T I O NEPO and external bypass circuits are not isolated from line voltage, and wiring must beinstalled according to local codes using conduit or suitable primary supply cables.



The Generator On signal is isolated from line voltage and canbe treated as NEC Class 2 wiring.

Use 14�20 AWG, 600V wire (UL) or 14�26 AWG, 300V wire(CSA) for all input control signals.

Neutral-to-Ground Bonding for Isolated Output

As required under safety regulations issued by various regulatoryagencies, the UPS cabinet must have a ground-bond connection for theneutral terminal of an isolated-output system. In such a system, thecustomer must make the neutral-to-ground (also referred to as N-G orneutral-to-earth) connection after selecting the desired outputconfiguration.

In isolated-output systems, a green and yellow neutral-to-groundbonding wire is supplied, with one end connected to the ground (earth)UPS terminal as shown in Figure 36. The other end of the wire (asshown by * in Figure 36) must be attached to the proper output neutralterminal, as specified in Figure 34 and Figure 35.

Balancing Receptacle LoadsFor Powerware 9170 UPS models with low-voltage output receptacles, itis recommended to divide loads between upper and lower receptaclesas equally as possible. (In some configurations, each set of receptaclesis limited to one half of the total UPS capacity.) Whether the cabinethas one panel containing eight receptacles, two panels containing16 receptacles, or three panels containing 24 receptacles, you shouldtry to supply half of the UPS output through the upper half of thereceptacles (X1) and the other half through the lower half of thereceptacles (X2), as shown in Figure 44.

OPERATION

The Powerware 9170 UPS operates in several different modes. Normallyit operates under internal control, called Auto mode, to automaticallyprotect loads connected to it. It also functions under operator control toenable manual override should servicing or testing be required.

Figure 45 is an illustration of the operating modes. In Auto mode, theUPS automatically switches between modes depending on line and loadconditions.

Double Conversion(Line Conditioning)

Internal Bypass

Battery Off

Figure 45. UPS Operating Modes Under Auto Mode Control

Double Conversion mode produces output power from the internal DCbus. The AC input power is rectified and boosted to supply this DC bus.The UPS switches automatically to and from Battery mode with nointerruption (0 ms transfer time) as AC input power drops and returns.Batteries are charged in this mode.

Battery mode produces power from the batteries to supply the internalDC bus.

Internal Bypass (Bypass) mode shunts power flow around the DC/ACinternal circuitry to keep the output powered with no line conditioning.Electromagnetic interference (EMI) and surge circuitry still protect theloads from voltage spikes and noise.

Operation


The High Efficiency (H.E.) mode is a user-programmable automaticmode of operation. This mode allows power to flow through the internalUPS bypass path for as long as AC input stays within the user-definedsetpoints. If the input voltage or frequency deviates beyond thesesetpoints, the Powerware 9170 system transfers to the DoubleConversion mode of operation. Complete loss of input voltage causesthe UPS to transfer to Battery mode. While in H.E. mode, the Powerware9170 system provides passive EMI filtering in the power path.

Off mode turns off the output and most internal circuitry. Within thismode, another mode (Sleep) turns off all internal circuitry when AC lineis not present and battery voltage drops to a low threshold. If AC inputvoltage is not present in Off mode, the user can direct the UPS to enterSleep mode by selecting the Battery Protect (BP) feature. When ACinput voltage returns in the Off mode (caused by a low battery alarmcondition), the UPS automatically recovers and, if the Auto Restartparameter is enabled, switches to Double Conversion. Auto Restart isenabled as a factory-default.

The UPS will not automatically recover from the Sleep mode, regardlessof the state of the Auto Restart parameter.

Removing Input Power

Always put the Powerware 9170 UPS into the Off mode before removinginput power. Powerware 9170 system batteries will discharge if theinput line voltage is disconnected or turned off without first turning offthe Powerware 9170 UPS.

If the input power source will be disconnected or turned off for morethan a day or two, you should put the UPS into Sleep mode. Do this byturning the UPS off, removing AC input power, and then pressing theOn button and selecting Battery Protect (BP). Sleep mode allows theUPS to remain unpowered for up to six months without having toremove or recharge batteries.

Failure to properly power down the Powerware 9170 UPS couldpermanently damage any installed batteries. Also, if batteries becomeseverely discharged, the UPS might not start immediately when inputpower is restored.

Turning the UPS On

If the UPS has been turned off, press the ON button through the frontpanel display to turn the UPS on again.

If the UPS has been manually set to operate in Bypass or Battery mode,change the System mode menu selection (menu 2) to Auto to return tonormal Auto mode operation.

NOTE The UPS will not start operating if AC input voltage or frequency is beyondacceptable limits or if the system mode selection is set to Battery. The UPS can not godirectly from Off to Battery.

COMMUNICATION

Powerware offers several methods of communicating with yourPowerware 9170 system in addition to the front panel display:

� CheckUPS� II Software

� RS-232 Communication

� Optional Interface Kits

� Relay Card

� BestLink� Telecom Modem Controller

� Optional Internal BestLink SNMP/WEB Adapter

� BestDock Communication Slots

� Dedicated Input Signals

CheckUPS II Software

Each Powerware 9170 UPS ships with CheckUPS II software and aninterface cable. To begin installing CheckUPS software, see theinstructions accompanying the CheckUPS software CD-ROM.

CheckUPS software uses an RS-232 serial link to communicate with theUPS, and (using Windows�) it provides you with up-to-date graphics ofUPS power and system data and power flow. It also gives you a completerecord of critical power events, and it notifies you of important UPS orpower information. If there is a power outage and the Powerware 9170system battery power becomes low, CheckUPS software canautomatically shut down your computer system to protect your databefore the UPS Low Battery shutdown occurs.

RS-232 Communication

You can connect the Powerware 9170 system to a computer runningspecial terminal emulation software available from Powerware. ThePowerware 9170 system communicates with your computer using anadvanced binary protocol. For more information, contact your servicerepresentative.

Communication


Optional Interface Kits

For computer systems that already have UPS monitoring software,Powerware offers interface cable kits for connecting the Powerware9170 system to your computer system. The kit includes the cable,adapters, and instructions.

Relay Card

This interface provides true relay contact output to peripheral devices.Outputs are user-selectable as normally open or normally closed.

BestLink Telecom Modem Controller

This interface provides remote monitoring and control of the UPSthrough a customer-supplied modem. In the event of an alarmcondition, this unit also provides automatic notification via numeric oralphanumeric pager, e-mail, or fax.

Optional Internal BestLink SNMP/WEB Adapter

This adapter provides the Powerware 9170 system with its own ethernetnetwork connection, allowing it to be remotely monitored andcontrolled via industry-standard internet browsers. The HTML interfaceenables UPS monitoring and management from anywhere on theinternet or within your intranet. In addition, third-party SimpleNetwork Management Protocol (SNMP) software packages may also beused to communicate remotely with the Powerware 9170 system. TheBestLink SNMP/WEB Adapter also allows UPS-dependent computersystems to automatically shut down during extended power outagesusing the NetWatch client software provided on the CheckUPS IICD-ROM or web site.

BestDock Communication Slots

The Powerware 9170 UPS has two communication slots that allow quickinstallation of the optional BestLink SNMP/WEB adapter or other similarcommunication interfaces. These interface adapters extend thecapabilities of the Powerware 9170 system to provide compatibility withnetwork and remote monitoring/management systems.

Communication


Dedicated Input Signals

Emergency Power-Off (EPO): Connection to a facility Emergency Shutdownswitch provides a method for emergency Powerware 9170 systemshutdown. Opening this connection creates an immediate shutdown ofthe Powerware 9170 UPS output.

Bypass: The signal from an external bypass switch, to isolate thePowerware 9170 system for maintenance purposes, tells the UPS to gointo Internal Bypass mode.

On-Generator: An external signal that the input power is being suppliedby a generator tells the UPS to accept wider input power frequencylimits.

See Figure 21 on page 31 and Figure 24 on page 34 to make theconnection for all dedicated input signals.

DB-9 Port Pin Functions

Table 10 explains the functions of the pins on the Powerware 9170 DB-9port. This port is on the Powerware 9170 UPS rear panel, as shown inFigure 42 on page 52.

Table 10. DB-9 Port Signals

Pin Function Description

1 RS-232 Receive Data Receives incoming RS-232 communication data. The data protocol is 9600 baud, 8 bits,no parity, 1 stop bit, no handshaking.NOTE In battery operation, a 5-second +Vdc (RS-232 low) signal applied to this pincauses the UPS to shut down after a delay of X minutes, regardless of the return of ACinput power. This time is defined by the External Shutdown mode parameter n, where nand X are related as follows:

n X n X n X0 2 3 3 6 201* 2 4 52 1 5 10

* For n=1, the UPS stays off when AC input power returns. For all other values of n, theUPS restarts 12 seconds after AC input power returns.

2 RS-232 Transmit Data Sends outgoing RS-232 communication data. The data protocol is 9600 baud, 8 bits, noparity, 1 stop bit, no handshaking.

MAINTENANCE

Routine Maintenance

NOTE Technicians must observe important safety precautions while performing thesechecks.

The Powerware 9170 system is designed to provide years of trouble-freeoperation. Its internal control system checks the batteries and inverterperiodically to ensure reliable operation. In fact, you'll probably findthat your Powerware 9170 system requires less maintenance than any ofyour other computer peripherals.

Nevertheless, the Powerware 9170 UPS and optional external batterycabinets do require some attention to assure continued reliable service.Powerware recommends that you schedule preventive maintenancechecks at least every six months. At these checks, the service technicianshould follow Powerware's recommended maintenance schedule, whichincludes the following items:

� Check operating environment for clean, cool, dry conditions.

� Inspect and clean the unit.

� Check operation of fans (power modules).

� Check and tighten all connections.

� View and record the alarm and inverter logs.

� Check the batteries.

� Check the displayed UPS readings against actual measurements andrecalibrate if necessary.

� Perform a system test.

� Check and record the values of the parameters in menu 3 online andon battery.

� Check the MOV surge suppression pack.

For more information on preventive maintenance checks, contact yourservice representative.

Maintenance


Storage Temperature

Store the Powerware 9170 battery modules (in the unit or batterycabinet) at �20 to +40°C (�4 to +104°F). Batteries will have a longershelf life if they are kept below +25°C (+77°F). The Powerware 9170UPS or battery cabinet without batteries may be stored at �40 to +60°C(�40 to +140°F).

External Bypass Switch (Make-Before-Break Only) Operation

Before turning the Powerware MBB bypass switch, you must press thered button located next to the handle. This button serves two purposes.It sends an electrical signal to the UPS to switch to the internal Bypassmode (if it is not already operating in that mode). The button alsooperates a mechanical interlock, to prevent the switch from beingturned without first signaling the UPS.

NOTE When the red button is released, the UPS remains in its internal Bypass modeand must be manually returned to the Auto mode by selecting that mode on the frontpanel display.

Battery Replacement

The Powerware 9170 hot�swappable feature allows you to replace thebattery modules easily without disconnecting the load or damaging thebatteries.

NOTE The Powerware 9170 UPS will operate with uncharged (or no) batteries, butwill have limited (or no) battery backup capability. Backup protection requires at leastthree battery strings for every four power modules.

Use the following procedure to replace battery modules in pairs.

1. Remove the front panel bezel(s) covering the battery modulesyou need to replace. Label the original module with maskingtape or some other identifier.

2. Grasp the battery module handle and press down on the latchrelease.

3. Pull the module out approximately 7� (17 cm) to the secondarystop on top of the module.

Maintenance


4. Press down on the secondary stop release, pull the module outfurther, and support the module weight with your second handas you remove the module from the cabinet. Remove thebattery module beside the first in a similar manner.

5. After removing a pair (one string) of battery modules, install areplacement pair. Replacements may be installed in emptycabinet slots before removing original battery modules.

6. When all desired battery modules have been replaced, reinstallthe front panel bezel(s).

Power Module Replacement

The Powerware 9170 hot�swap feature allows you to replace a powermodule easily without disconnecting the load or damaging the UPS.

NOTE The UPS may switch to internal bypass if the remaining power modules areinsufficient to supply the required power. If empty slots exist, install replacementmodules before removing original ones.

Use care in removing and installing power modules. To remove a powermodule:

1. Loosen the thumbscrew on the module handle. Press down onthe latch release at the center of the module handle and pull thehandle down.

As the handle fully extends, the module disconnects. Slide themodule slowly out of the cabinet.

2. Use two hands to support the module. When fully extended,lower the front down slightly and lift the rear edge over thesafety stop on the center support rail.

3. Treat the original and replacement modules with care to avoiddamaging connectors or internal circuitry. Label the originalmodule with masking tape or some other identifier. Record theserial number of the replacement module for your warranty.

Maintenance


4. Insert a replacement module by sliding it carefully into thecabinet. Lower the front down slightly and lift the rear edgeover the safety stop on the center support rail. Keep the modulehandle extended until the module is fully inserted.

5. Push the module in firmly. Raise the power module handle tosecure the module into the cabinet. Be sure the handle latchsnaps into place. Tighten the thumbscrew on the handle.

Troubleshooting


Table 19 contains descriptions of non-critical alarm messages.Non-critical alarms are not as urgent as critical alarms, but should beattended to as soon as convenient to avoid the problem becomingcritical.

Table 19. Non-Critical Alarm Messages

Alarm Message What It Means What to Do

Near Low Battery (B) The battery voltage has reached theNear Low Battery setpoint.

If the voltage increases, the alarm clears automatically. Ifit drops further, it will cause a Low Battery alarm.

Low Runtime (D) Batteries in the unit are nearlydischarged.

Perform an orderly shutdown of all equipment and waitfor AC input power to return. When AC input powerreturns, the UPS begins recharging batteries andautomatically restarts.

Check Memory (O) The configuration as stored in thesystem memory may have beencorrupted.

Look in the alarm log for the slot number of the failedmodule. Contact your service representative.

Check Battery (M) The batteries have failed anautomatic system test.

See Table 9 on page 67 and Table 20 on page 86 forinformation about reason codes. Contact your servicerepresentative.

Low Redundancy (U) The number of active power modulesis too low to provide the programmedredundancy level to protect thecurrent load.

The unit is able to protect the equipment, but will not befault tolerant. To regain the desired redundancy, eitheradd power modules or reduce the load. See Table 9 onpage 67 and Table 20 on page 86 for information aboutreason codes.

Alarm Reason Codes

Some alarms have a reason code as well as the alarm code. These reasoncodes may help you to interpret and isolate the cause of an alarm.Table 20 contains a listing of all reason codes along with the associatedalarm codes. It also gives an interpretation of the reason, and asuggested corrective action.

Table 20. Alarm Reason Codes

Alarm Code andReason Code

What it Means What to Do

M Check BatteryOpen Cell(Reason code 4)

A battery (pair of modules) has failedan open cell test.

Look in the alarm log for the slot number of the failedmodules. Verify that both battery modules are properlyinstalled. If properly installed, replace both batterymodules.

M Check BatteryWeak Battery(Reason code 5)

The system batteries have degradedto the point where system runtime isless than the designed rating.

Replace all battery modules.

T Call ServicePhase Error(Reason code 6)

The UPS has detected the inputphase rotation to be incompatiblewith its output wiring and will notstart up.

Correct the input wiring problem and restart the UPS.

T Call ServiceModule Failure(Reason code 7)

A power module has detected aninternal fault and has shut down.

Look in the alarm log for the slot number of the powermodule and replace the defective module.

T Call ServiceExcessive Transfers(Reason code 8)

The UPS has detected an excessivelyhigh number of automatic transfersfrom High Efficiency mode, and hasswitched to Double Conversion (Auto)mode.


T Call ServicePrecharge Failure(Reason code 9)

A power module has detected aninitialization sequence problem andwill not start up.

Look in the alarm log for the slot number of the affectedmodule. Contact your service representative.

U Low RedundancyInsufficient Batteries(Reason code 10)

The UPS load exceeds 2800 watts perbattery string. The system will protectthe load during short power outages,but battery degradation or damagemay result.

Reduce the load or install additional battery modules (twomodules per string).

U Low RedundancyInsufficient Modules(Reason code 11)

The number of active power modulesis too few to provide the programmedredundancy level while protecting theload. The UPS will protect the load,but will not be fault tolerant.

Reduce the load or install additional power modules.
