Alarm or Condition
Possible
Cause
Action
ON BATTERY
Yellow
LED is on.
One short beep every five
seconds.
A utility
failure has
occurred and
the UPS is in
Battery
mode.
The UPS is powering the equipment with battery power. Prepare your
equipment for shutdown.
BATTERY LOW
Yellow
LED is on.
Continuous beep for ten seconds.
The UPS is in
Battery mode
and the
battery is
running low.
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
for estimated runtimes and for
configuration information.
When utility power is restored, the UPS restarts automatically, provides
power to the load, and charges the battery.
BATTERY BREAKER
Red
LED is on.
One beep every three seconds.
The UPS
does not
recognize the
internal
batteries.
Verify that the UPS battery circuit breaker is in the ON (|) position. If the
condition persists, contact your service representative.
ON BYPASS
Yellow
LED is on.
One beep every three seconds.
The UPS is in
Bypass
mode.
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).
BYPASS UNAVAILABLE
Yellow
LED is flashing slowly.
One beep every second.
Bypass is not
available
because the
UPS may be
receiving
bypass utility
power that
may be
unstable or

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.

One beep every three
seconds.
The UPS

ed.
Verify that all battery trays are fully seated and locked in place. If the
condition persists, contact your service representative.
