Possible cause
The load level is >101% and <110%
of the uninterruptible power supply
rating.
See "Behavior on overload" on page
26.
The load is >110% of the
uninterruptible power supply rating.
See "Behavior on overload" on page
26.
The battery voltage levels have
exceeded the maximum allowable
limits.
A battery charger fault has been
detected.
The uninterruptible power supply has
detected an abnormally low
impedance placed on its output and
considers it a short circuit.
The uninterruptible power supply 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 uninterruptible power supply has
detected that one or more fans are
not functioning correctly.
Action
Immediately remove some of the
equipment from the uninterruptible
power supply. The alarm clears when
the load drops below 5% of the set
point.
Shutdown is imminent.
The alarm clears when the load drops
below 5% of the set point.
The uninterruptible power supply
turns off the charger until the next
power recycle. Contact your service
representative.
The uninterruptible power supply
turns off the charger until the next
power recycle. Contact your service
representative.
The uninterruptible power supply
shuts down after five line cycles.
Make sure that the fans are spinning
and that the air intake vents on the
uninterruptible power supply are not
blocked. After the maximum
temperature is reached, the
uninterruptible power supply shuts
down.
Contact your service representative.
This is an alarm only. Contact your
service representative immediately
and remove the load.
