ROUBLESHOOTING
This section explains what to do in the event of an alarm condition, or when any other “out of the ordinary”
event occurs on the UPS.
12.1
Alarm sounds and/or Alarm LED lights up
1.
Go to the Event Log and look at the Active Alarm Display to determine the nature of the alarm. See
“Navigating to the event log” and “Active Alarm display” on page 26.
2.
Look for the appropriate heading below according to the nature of the alarm, and follow the
instructions.
12.2
Electricity returned but UPS remains in Battery
Mode
Check the external circuit breaker for the AC line. The circuit breaker may be off.
12.3
Battery Test failed
It may be that an automatically scheduled battery test was executed shortly after the end of a power
outage, when the battery was still charging. Wait until about two hours after the return of the AC power and
perform a manual battery test. This should clear the alarm.
12.4
The UPS remains in Bypass mode
The UPS may have been put in Bypass mode manually. In such a case, the lower left quadrant of the Main
Screen says “Manual Bypass”. To manually return the UPS to Normal mode, see “Manually entering or
leaving bypass mode” on page 47
12.5
Sync Fault
Verify that the AC Input and the Bypass Input lines are connected to the UPS in proper phase sequence.
Verify that AC of the proper frequency (Hz) is being used. (See on page 60.)
