ActionPossible CauseAlarm or Condition
Shutdown - Low Battery
Shutdown imminent. Prepare equipment for shutdown.
Bypass
UPS is in Bypass mode. The equipment is transferred to utility power; however, the
utility power continues to be passively filtered by the UPS.
Check for one of the following alarms: Overtemperature,
Overload, UPS Failure, or Battery Service.
Bypass
Bypass is not available. Input
voltage is not within ±12% of
nominal or input frequency is
not within ±3% of nominal.
The UPS is receiving utility power that may be unstable or
in brownout conditions. The UPS continues to supply power
to your equipment. If conditions worsen, the UPS may
switch to battery power.
Battery Service
The battery may be fully
discharged.
Plug the UPS into a power outlet (apply utility power on
hardwired models) for 24 hours to charge the battery. After
charging the battery, press and hold the button for
3 seconds; then check the indicator.
If the indicator is still on, see “UPS Maintenance” on
page 57 to replace the battery.
The battery is not connected
correctly.
Check the battery connections. Call your service
representative if the problem persists.
Site Wiring Fault
(120V models only)
Ground wire connection does
not exist or the line and
neutral wires are reversed in
the wall outlet.
Have a qualified electrician correct the wiring.
To disable this alarm, see “Configuration Mode” on
page 47.
Overtemperature
UPS internal temperature is
too high. The UPS switches to
Bypass, allowing the UPS to
cool.
Turn off the UPS. Unplug or remove utility power from the
UPS. Clear vents and remove any heat sources. Ensure the
airflow around the UPS is not restricted. Wait at least 5
minutes and restart the UPS. If the condition persists,
contact your service representative.
Overload
Continuous audible alarm
Power requirements exceed
UPS capacity (101–150% for
30 seconds) or the load is
defective.
Turn off the UPS. Unplug or remove utility power from the
UPS. Remove some of the equipment from the UPS. Wait at
least 5 seconds until all LEDs are off and restart the UPS.
If the overload condition persists (101–110% for 2 minutes
or 111–150% for 30 seconds), the UPS automatically shuts
down.
