Quick Installation
Connect the UPS to
a 120V AC electrical outlet.
Make sure the outlet does not share a circuit
with a heavy electrical load such as an air
conditioner or refrigerator.
Plug your equipment into
the UPS.
The battery backup receptacles A provide
filtered AC power during normal operation and
provide battery backup power during blackouts
and extreme voltage irregularities. Connect your
computer and monitor to the battery backup
receptacles.*
One or more surge-only receptacles B attached
to short cords at the rear of the UPS provide AC
line protection without battery backup. These
receptacles will protect equipment that would
overload the UPS or greatly reduce backup time
if connected to the battery backup receptacles.
Note: High-amperage equipment such as laser printers,
refrigerators, air conditioners and electric heaters should not
be connected to the UPS.
* Your UPS is designed to only support computer equipment.
You will overload the UPS if the total VA ratings for all the
equipment you connect to the (A) outlets exceeds the UPS’s
Output Capacity. To find your equipment’s VAratings, look on
their nameplates. If the equipment is listed in amps, multiply
the number of amps by 120 to determine VA. (Example: 1 amp
x 120 = 120 VA.) If you are unsure if you have overloaded the
(A) outlets, run a self-test (see “MUTE/TEST” button
description).
Select UPS Operating Mode.
Press the ON/OFF button to toggle the UPS
between the ON (“ ” LED lit) and the OFF
(“ ” LED not lit) modes.
