Silencing the Alarm

Press any button on the control panel to silence the alarm. Check the alarm condition and perform the
applicable action to resolve the condition. If any new alarm becomes active, the audible alarm resumes,
overriding the previously silenced alarm.
Possible Cause
The UPS has detected a fault in
the inverter circuit while
attempting a recovery from
Bypass mode or Converter
mode.
The UPS has detected that one
of its heat sinks has exceeded
the maximum defined
operating temperature. Possible
fan failure.
There is EEPROM data
corruption due to a failed
device or incorrect flash
upgrade.
The UPS has detected an
abnormally low impedance
placed on its output and
considers it a short circuit.
The UPS has detected that one
or more fans are not
functioning properly.
Action
Contact your service representative.
The UPS transfers to Bypass mode if available.
If the bypass is not available or the UPS is in
power on or standby mode, the UPS transfers
to fault mode.
Ensure that the fans are spinning and that the
air intake vents on the UPS are not blocked.
Once the maximum temperature is reached,
the UPS shuts down.
Contact your service representative.
If the UPS is in Normal mode, the UPS
transfers to Bypass mode if available,
otherwise, the UPS shuts down after three to
five line cycles.
If the UPS is in Battery mode, the UPS shuts
down after three to five line cycles.
This is an alarm only. Contact your service
representative immediately and remove the
load.
