Service and Troubleshooting
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 25% capacity. See Table 27 on
page 138 for estimated runtimes and "Setting the Battery Low Alarm
Level" on page 104 for configuration information.
hen utility power is restored, the UPS restarts automatically,
provides power to the load, and charges the battery.
Verify that the UPS battery circuit breaker is in the ON (|) position. If
the condition persists, contact your service representative.
The equipment transferred to bypass utility power. Battery mode is
not available and your equipment is not protected; however, the
utility power continues to be passively filtered by the UPS. Check for
one of the following alarms: overtemperature, overload, UPS failure,
hot swap, or remote emergency power-off (REPO).
Check the bypass utility. The UPS continues to supply power to your
equipment. Check for one of the following alarms: bypass over or
under voltage, bypass over or under frequency, or bypass unavailable.
If the condition persists, contact your service representative.
Verify that all battery trays are fully seated and locked in place. If the
condition persists, contact your service representative.
Remove some of the equipment from the UPS. The UPS continues to
operate, but may switch to Bypass mode if the load does not
decrease. The alarm resets when the condition becomes inactive.
