UPM Load and Battery Indicators
Example:
UPM display showing normal operation
(Fully charged batteries with 60% load shown)
UPM display showing in battery backup operation
(Batteries 80% charged with 60% load shown)
UPM display showing an overload condition (Batteries 100%
charged and greater than 100% load shown)
UPM display showing over-temperature condition
(Batteries 80% charged with 80% load shown)
UPM display showing a bad battery condition
(Inspect or replace battery unit loaded to 60%)
NOTE:
Depending on the charge state of the battery, it is possible that the
battery charge level LEDs may be ashing (this is normal).
Initial Startup
With the connected equipment powered off, perform an initial test of the
UPM backup function by pressing the Test/Silence button on the front pan-
el. During this test, the Battery LED ( ) on the front panel should briey
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 few seconds while the power cord is
unplugged. The Battery 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 unit is not overloaded. If
the unit is overloaded all load LED’s will be on the fault LED ( ) will ash,
remove the least critical devices from the UPM one by one until the overload
LED 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 nal test is completed, the UPM will be ready to use.
