3.6 Operation and Functional Test
1. Plug in the AC input cord to the rear panel and turn on the UPS by
pressing the “On/Off” switch for 2 seconds. The UPS will beep and the
front panel Normal Mode LED will light.
2. The UPS may be overloaded if the buzzer sounds continuously and the
Overload LED lights. Unplug the least critical devices, such as a printer,
etc… If the buzzer is still sounding, the battery or UPS may be faulty.
Contact your local dealer for assistance.
Note: Backup all unsaved files before you perform the following
functional test.
3. To test the backup function, you may unplug the power cord of the UPS or
simply press the On Button on the front panel. During this test, observe
that your equipment operates properly and without interruption. If you
leave your UPS on continuously, it is a good idea to perform a “Test” at
least once a month.
If you unplug the power cord, all models will beep once every 4 seconds.
You can press the Test Button to silence the alarm. The Battery Mode
LED will light. Plug the power cord back in after a few seconds.
If you press the On Button, the Battery Mode graph will light momentarily.

temperature locations. Plug in the power cord.
