Action Possible Cause Alarm or Condition
Overload
LED is on.
1 beep every second.
Power requirements exceed the
UPS capacity (greater than
100% of nominal; see page 84 for
specific output overload
ranges). Remove some of the equipment from the UPS. The
UPS continues to operate, but may switch to
Bypass mode or shut down if the load increases.
The alarm resets when the condition becomes
inactive.
Overtemperature
LED is on.
1 beep every second.
The UPS internal temperature is
too high or a fan has failed.
At the warning level, the UPS
generates the alarm but remains
in the current operating state.
If the temperature rises another
10
° C, the UPS transfers to
Bypass mode or shuts down if
bypass is unusable.
If the UPS transferred to Bypass mode, the UPS will
return to normal operation when the temperature
drops 5
° C below the warning level.
If the condition persists, shut down the UPS. Clear
vents and remove any heat sources. Allow the UPS
to cool. Ensure the airflow around the UPS is not
restricted. Restart the UPS.
If the condition continues to persist, contact your
service representative.
Battery Overvoltage
LED is on.
1 beep every second.
The UPS battery voltage is too
high. The UPS turns off the charger until the next power
recycle. Contact your service representative.
