Possible Cause
One of the conditions listed in
"Running Automatic Battery
Tests" on page 55 was not
present.
A utility failure has occurred
and the UPS is in Battery mode.
The UPS does not recognize the
internal batteries.
Battery voltage is lower than the
batteries disconnected level
defined for this UPS. This may
be due to a blown fuse,
intermittent battery
connection, or battery cable
being disconnected.
Battery time remaining or
battery capacity is lower than
the battery low warning level
defined for this UPS.
Communication to external
devices stops because the UPS
has entered a state where it may
abruptly stop operating without
further notice unless utility
returns.
A weak battery string was
detected during the last battery
test.
A faulted battery string has
been detected and as a result,
the charger is disabled.
Utility level has fallen below the
Utility Not Present threshold
(typically <25 to 50V).
Action
Resolve the condition, then restart the test.
The UPS is powering the equipment with
battery power. Prepare your equipment for
shutdown.
If the condition persists, contact your service
representative.
Verify that all batteries are properly connected.
If the condition persists, contact your service
representative.
This warning is approximate. The actual time to
shutdown may vary depending on the UPS load
and presence of an External Battery Module
(EBM).
The alarm is issued when the battery time
remaining reaches zero. All connected devices
should have already shut down gracefully.
This is a warning notice. Dell recommends
that you replace the batteries soon.
Contact your service representative.
The UPS transfers to Battery mode if
supporting the load. The UPS shuts down if it
is not supporting the load.
