the output connectors.

Self Test
The UPS checks vital functions when it is first
plugged in and indicates the status with the three
LEDs on the front panel. A green LED indicates
normal AC output. A blinking yellow LED shows the
battery is being charged. The UPS will continuously
monitor the condition of the battery. If the battery
cannot be charged, is disconnected or takes too long
to charge, a code is represented in the LED Display.
NOTE:
The System Code Status Chart on the back of
the UPS (and on page 11 of this manual) provides a
quick reference for interpretation of the system status
LEDs.
On Battery
If the AC input power source to the UPS rises too
high, too low or fails, the UPS will switch to the
internal inverter to deliver power to the outlets from
the battery(ies). The LEDs will indicate that the UPS
is on battery. An audible alarm will also sound every
minute.
