Troubleshooting
All LEDs are off and the UPS is wired to input utility power
The UPS is shut down or the battery
module is discharged from an extended
outage.
None. The UPS will restart automatically when utility power is restored and
the battery module has a sufficient charge.
The overload LED is illuminated and the UPS emits a sustained alarm tone
The UPS is overloaded. The connected equipment exceeds the specified “maximum load” as defined
in Specifications listed on the rating label located on the UPS.
The alarm remains on until the overload is removed. Disconnect nonessential
equipment from the UPS to eliminate the overload condition.
The UPS continues to supply power as long as it is online and the circuit
breaker does not trip. The UPS will not provide power from battery
module(s) in the event of a utility voltage interruption.
The replace battery/battery disconnected LED is illuminated
The replace Battery/battery
disconnected LED flashes and a short
beep is emitted every two seconds to
indicate the battery is disconnected.
Check that the battery module connectors are fully engaged.
Weak battery module. Allow the battery module to recharge for 24 hours and perform a self-test. If
the problem persists after recharging, replace the battery module.
Failure of a battery module self-test.
Replace battery/battery disconnected
LED
illuminates and the UPS emits short
beeps for one minute. The UPS repeats
the alarm every five hours.
Allow the battery module to recharge for 24 hours. Perform the self-test
procedure to confirm the replace battery condition. The alarm stops and the
LED clears if the battery module passes the self-test.
If the battery module fails again, it must be replaced. The connected
equipment is unaffected.
The input circuit breaker trips
The connected equipment exceeds the
specified “maximum load” as defined
in Specifications listed on the rating
label located on the UPS.
Unplug all nonessential equipment from the UPS.
Reset the circuit breaker.
The AVR boost or AVR trim LEDs are illuminated
The system is experiencing very high or
low utility voltage. Have a qualified service person check your facility for electrical problems. If
the problem persists, contact the utility company for further assistance.
