Possible cause
A utility failure has occurred and the UPS is in
battery mode.
The UPS is in Battery mode and the battery is
running low.
The batteries are disconnected.
The battery test is failed due to bad or
disconnected batteries.
The batteries need charging or service.
Power requirements exceed the UPS capacity
(greater than 100% of nominal;
see "User Settings" for specific output overload
ranges).
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 shuts down.
The input source is not connected correctly.
Action
The UPS is powering the
equipment with battery power.
Prepare your equipment for
shutdown.
This warning is approximate, and
the actual time to shutdown may
vary significantly. Depending on
the UPS load and number of
Extended Battery Modules (EBMs),
the "Battery Low" warning may
occur before the batteries reach
20% capacity.
Verify that all batteries are
properly connected. If the
condition persists, contact your
service representative.
Verify that all batteries are
properly connected. If the
condition persists, contact your
service representative.
Apply utility power for 48 hours to
charge the batteries. If the
condition persists, contact your
service representative.
Remove some of the equipment
from the UPS. The UPS continues
to operate, but may shut down if
the load increases. The alarm
resets when the condition
becomes inactive.
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.
Check the input and battery
connections.
