Notes1. Nominal (NOM) current is based on full rated output load.2. Maximum (MAX) current includes the short duration for battery recharge conditions.3. UPS input cables must be run in separate conduit from output cables.4. Reserved.5. Nominal battery voltage is shown at 2.0 volts/cell per NEC 480-2.6. Power cables from UPS DC link to batteries should be sized for a total maximum 2.0 volt line drop (measured at UPS) at maximum discharge current.7. Recommended AC output overcurrent protection represents 125% of nominal full load current (continuous) per NEC 220-3(a).8. UPS output load cables must be run in separate conduit from input cables.9. Minimum sized grounding conductors to be per NEC 250-95. Parity sized ground conductors are recommended. Neutral conductors to be sized for full

capacity per NEC 310-16 Note 10.10. Wiring requirements:

AC Output: 3-phase, 4-wire plus groundDC Input: 2-wire (positive and negative) plus groundSingle Source AC Input: 3-phase, 4-wire plus groundDual Source AC Input:

Converter Input: 3-phase, 3-wire plus groundBypass Input: 3-phase, 4-wire plus ground

11. All wiring is to be in accordance with national and local electrical codes.12. Minimum access clearance is 3 feet front and 1 foot above the UPS.13. Top or bottom cable entry through removable access plates. Cut plate to suit conduit size, then replace.

Additional Notes1. If site configuration includes a back-up emergency generator, it is recommended that the engine generator set be properly sized and equipped for a UPS

application. Generator options would typically include an isochronous governor (generator frequency regulation) and a UPS compatible regulator(generator voltage regulation). Consult generator manufacturer for required generator options and sizing.

2. If site configuration includes an automatic transfer switch, refer to the Liebert Power Line titled Criteria for Application of Automatic Transfer Switches(ATS) with Uninterruptible Power Supply (UPS) Systems 91K-PLT-48-02. It is also recommended that the transfer switch be equipped with auxiliarycontacts. Consult transfer switch manufacturer for required transfer switch options and sizing.

Table 5 Alarm Messages

Alarm Message Meaning Corrective Action

Alarm Event The Input contact isolator allows theuser to define events outside of theUPS that will cause an alarm to showon the UPS. One of those events hasoccurred.

Scroll through the alarm messages todetermine which outside alarm hasoccurred. Correct the alarm sourceand the alarm message will clear.

Bad Connection An internal connection between PC

boards has come loose or is broken.

Contact Liebert Global Services.

Battery Charger Inhibited:load above threshold

The input contact isolator option hastriggered inhibition of the batterycharger and the load is above thethreshold selected by the user toinhibit battery charging.

This alarm normally comes when theunit is being fed by an alternatesource such as a generator. Batterycharging has been temporarilyinhibited to reduce the load on thesecondary source. If the normal utilityis supplying the load check theprogramming of the ICI option in theUsers Option Manual. If the unit isbeing temporarily supplied by asecondary source, try to reduce theload below that sources capacity sothe system can resume charging.Contact Liebert Global Services ifyou have questions or problems.

Battery Test Failed The battery test has detected a weakbattery.

If there is no charger alarm, then thebattery has either weak cells or looseconnections. Contact Liebert GlobalServices for battery service.

Battery Voltage Unstable A battery cell(s) is not functioningproperly or battery system wiring isloose.

Contact Liebert Global Services forbattery service.

Bypass Out-of-Sync Bypass input is not stable. UPSinverter output is not synchronizedwith the input power. Automatictransfers to bypass are prohibited.This is usually a temporary condition.

If the problem does not correct itselfin 15 minutes contact Liebert GlobalServices. Check utility source.

Bypass Overload An overload condition has exceededthe capacity of the bypass. If notcorrected a fuse will blow resulting ina system shutdown.

Correct the overload condition. CallLiebert Global Services if thecondition persists.

Bypass Power Supply Failure Control power is outside theacceptable limits. Bypass is notavailable.


Bypass SCR Short The system has sensed unexpectedinput voltage. The UPS will transferto bypass.


Bypass Sensing Failure Unit will transfer to bypass due to aninternal sensing failure.


Bypass Voltage

Out of Tolerance

Incorrect BypassInput Frequency

Input power voltage or frequency is

outside of the specified tolerance.Automatic transfers to bypass areprohibited except in the case ofinverter failure.

In this condition a manual transfer to

bypass is not recommended becauseit will be a momentarily interruptedtransfer.

Cant Execute Battery Test:Not Recharged

The battery has discharged toorecently (within 72 hours of thescheduled test time).

No corrective action is required. Thenext scheduled battery test will beperformed.

Make sure battery breaker is closed.Contact Liebert Global Services ifthis condition persists for more than15 minutes.

Charger Fuse Blown The battery circuit breaker is open orthe battery charger fuse has beenblown. The charger is no longercharging the batteries.

Check the battery circuit breaker. Ifthe breaker is open, try to reset. If thebreaker will not reset or is not open,Contact Liebert Global Services.

Charger Hardware Shutdown Malfunction in the battery chargersection. If this condition persistswithout service, the batteries can bedischarged.


Dial Out Attempt Failed If the unit is equipped with an internalmodem, it attempted to dial out dueto an event or command on themodem connected to the UPS. Theattempt was unsuccessful after 3tries.

Check the phone numberprogrammed into the modem. Checkthe receiving modem. Check themodem operation.

Excessive RetransfersAttempted

Several automatic retransferattempts (20 attempts during 15minutes or less) have been made toretransfer the load from bypass (ifavailable) back to the UPS. The UPShas not been able to consistentlysustain the load, because of anoverload condition or an inverterfailure. The load will remain onbypass.

Check other messages for inverterfailure. Determine cause of theoverload and reduce the load. If theproblem cannot be corrected, callLiebert Global Services.

Emergency off. Recycle inputto restart.

The UPS has been shut down froman external contact (REPO) or thefront panel EPO switch.

Perform a UPS start-up procedurewhen the conditions causing theexternal shutdown have beencorrected. See 3.2.3 - Manual

Restart after Low BatteryShutdown.

Fault Transferred to Bypass The unit transferred to bypass due toa fault or overload in the system. Thisalarm accompanies the other alarmsthat caused the fault.

Review other alarms. Removecondition-causing fault if possible(e.g., reduce overload). Call LiebertGlobal Services if fault cannot becleared.

Ground Fault detectedon DC bus.

There is a ground fault in the batterycabinet or battery wiring.

Contact Liebert Global Servicesimmediately.

Input Voltage Out-of-Tolerance

The line to line voltage of the inputpower is outside the acceptablerange. In this situation, if the voltageis low the battery will supply power tothe critical load through the UPS.

If this condition persists the batterywill eventually completely discharge.Check your electrical wiring. Checkwith your utility.

Inverter Fuse Blown The inverter fuse has openedindicating a failure in the invertersection of the UPS. The unit willtransfer the load to Bypass.

Contact Liebert Global Servicesimmediately.

Inverter Neutral SCR Open On units equipped with the isolatedneutral option, the SCR has failed.


Inverter Startup Overvolt The inverter bus is too high duringthe walk-in period. Possible fault onthe PFC.
