Battery Power
If the utility power fails, the UPS can provide power to the connected equipment from its internal
battery for a finite period. The UPS sounds an alarm, four beeps every 30 seconds, while
operating on battery power. The alarm stops when the UPS returns to on-line operation.

On-Battery Power Indicator
When the on-battery power indicator is lit the UPS is supplying battery power to the connected
equipment. Refer to On-Battery Operation, page 13, for details.

The 5-LED display on the right of the front panel shows the present charge of the UPS’s battery as
a percentage of the battery’s capacity. When all five LEDs are lit, the battery is fully charged.
The LEDs extinguish, from top to bottom, as the battery capacity diminishes. The battery
capacity threshold is shown in the figure to the left (it is not listed on the front panel display).
As a low battery warning, any LEDs illuminated (for the given capacity) will flash. The low
battery warning setting can be changed from the rear panel (see Low Battery Warning Level, page
13) or through the optional PowerChute software.

Overload
When the UPS is overloaded (when the connected equipment exceeds the maximum specified in
the maximum load defined in the Specifications at the APC web site), the overload LED comes on
and the UPS emits a sustained tone. The alarm remains on until the overload is removed. The
UPS continues to supply power as long as it is on line and the breaker does not trip, but it will not
provide power from batteries in the event of a utility voltage interruption. Disconnect
nonessential equipment from the UPS to eliminate the overload. If a continuous overload occurs
while the UPS is on battery, the UPS will turn off its output in order to protect itself from possible
damage.

Replace Battery
If the battery fails a self-test, the UPS emits short beeps for one minute and the replace battery
LED illuminates. (If the LED flashes, the battery is disconnected.) The UPS repeats the alarm
every five hours. Perform the self-test procedure after the battery has charged for 24 hours to
confirm the replace battery condition. The alarm will stop if the battery passes the self-test.

Low Battery
When the UPS is operating on-battery and the energy reserve of the battery runs low, the UPS
beeps continuously (by default) until the UPS shuts down from battery exhaustion or returns to
on-line operation. The low battery warning interval can be changed through optional software.

Shutdown Mode (via optional software or an accessory)
In shutdown mode the UPS stops supplying power to the connected equipment, waiting for the
return of utility power. If there is no utility power present, external devices (e.g., servers)
connected to the computer interface or the accessory slot can command the UPS to shut down.
This is normally done to preserve battery capacity after the graceful shutdown of protected
servers. The UPS will scroll the front panel indicators sequentially in shutdown mode.
