Low Battery Warning Level
By default, the low battery warning occurs when there are approximately two minutes of
on-battery run time remaining. This may not be enough time to gracefully shut down some
protected computer systems.
To change the warning interval, press the rear panel Sensitivity button while pressing and holding
the front-panel on button.

7 min.
Brightly lit: The low battery warning interval is approximately two minutes.
Dimly lit: The low battery warning interval is approximately five minutes.
Off: The low battery warning interval is approximately seven minutes.
On-Battery Operation
The Smart-UPS will switch to battery operation automatically should the utility power fail. While
running on battery, an internal alarm will sound (periodic beeps). Press the on button, on the front
panel, to silence the UPS alarm (for the current alarm only). The optional PowerChute software
allows you to change the audible indicator.
If the utility power does not return, the UPS will continue supplying power to the connected
equipment until exhausted. A continuous beeping will sound approximately two minutes before
the UPS’s final low battery shutdown. If using a computer, you must manually save your files and
power down before the UPS turns itself off, unless you are using optional PowerChute interface
software that provides automatic, unattended shutdown.
Refer to On-Battery Run Time, page 20, for approximate run time data.
