Initial Startup
With the connected equipment powered off, perform an initial test of the UPS backup function
by pressing the Test/Silence button on the front panel. During this test, the Battery LED ( ( )
on the front panel should briefly ( ) illuminate. It is also possible to test the backup function by
unplugging the UPS input power cord. If you choose to test the UPS in this manner, you will
note that the UPS 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 UPS 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 and the fault LED ( )
will
flash.
Remove the least critical devices from
the UPS 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
UPS. When this final test is
completed,
the UPS
will
be ready to
use.
