Low Battery Warning
Level
The low battery warning beeps to indicate low on-battery run time. It beeps periodically (ap-
proximately three times per minute) when less than seven minutes of run time remain. The beeps
are continuous when only two minutes of run time remain.
This may not be enough time to shut down some protected computer systems. To change the
warning interval default setting, press the voltage sensitivity button while pressing and holding the
front-panel
button.

120V models only: This indicator lights up when the UPS is connected to an improperly wired
AC power outlet.
ON BATTERY OPERATION
The Smart-UPS switches to battery operation automatically if the utility power fails. While running on-battery, an internal alarm
sounds (periodic beeps).
Press the
button (front panel) to silence the UPS alarm (for the current alarm only). You can change the audible indicator if
you are using the PowerChute software.
If the utility power does not return, the UPS continues to supply power to the connected equipment until exhausted. The UPS
will begin to beep continuously approximately two minutes before the UPS final low battery shutdown. If using a computer, you
must manually save your files and power down before the UPS turns off, unless you are using PowerChute interface software
that provides automatic, unattended shutdown.

ETERMINING ON BATTERY RUN TIME
UPS battery life differs based on usage and environment. It is recommended that the battery/batteries are changed once every
three years.
See the APC web site, www.apc.com
