Applying Power to the UPM
For North American versions, connect the power cord to a verified grounded 3 wire receptacle. For
international versions, unplug the cord from your computer and plug into the inlet of the UPM. Then use the
cord supplied with the UPM to connect the UPM to your computer.
For North American versions, verify that the Site Wiring Fault LED is off. Once properly connected and
initially checked, turn on the UPM by pressing and holding the front panel On/Off switch for 3 seconds.
Operational Tests
Observe the front panel of the UPM. The following table shows how the front panel LED should appear
upon start-up.

With the connected equipment powered off, perform an initial test of the UPM backup function by pressing
the Test/Silence button on the front panel. During this test, the Battery Mode LED on the front panel should
briefly illuminate. It is also possible to test the backup function by unplugging the UPM input power cord. If
you choose to test the UPM in this manner, you will note that the UPM will beep every four seconds while
the power cord is unplugged. The Battery Mode LED will also illuminate constantly.
Once you have performed an initial test of the UPM backup function, turn on the connected computer
equipment. Verify that the Overload LED is off. If the Overload LED is illuminated, remove the least critical
devices from the UPM one by one until the overload light is extinguished. With the connected loads
powered up, perform the backup test once again by pressing the Test/Silence button or unplugging the
UPM. When this final test is completed, the UPM will be ready to use.
Please Note:
If you leave your UPM on continuously, it is a good idea to perform a test at least once a month.
If you are utilizing Communications Manager software, you can configure the system to
automatically self-test periodically.
