Back-UPS ES is switched OFF. Plug your printer, fax machine,
scanner, or other peripherals that do not need battery power into
these outlets.

Surge Protection

These outlets are powered whenever the Back-UPS ES is
switched ON. During a power outage or other utility problems
(brownouts, over-voltages), these outlets will be powered for a
limited time by the Back-UPS ES. Plug your computer,
monitor, and other peripheral devices into these outlets.

Press the ON/OFF switch to turn on the unit.

A single short beep and the green “Power On” indicator
confirms the Back-UPS ES is on and ready to provide
protection.

The Back-UPS ES should charge for at least 16 hours to
ensure sufficient runtime. The unit is being charged whenever
it is connected to utility power, whether the unit is turned ON
or OFF.
If the red Building Wiring Fault indicator (located on the end
near the power cord) is lit, your building wiring presents a
shock hazard that should be corrected by a qualified
electrician.

Transfer Voltage and

Sensitivity Adjustment

(Optional)

In situations where the Back-UPS, or connected equipment, is too
sensitive to the input voltage, it may be necessary to adjust the
transfer voltage. To adjust the transfer voltage:

1. Plug the Back-UPS into the utility power source. The Back-

will be in “Standby mode” (no indicators are lit).

2. Press the ON/OFF push button fully in for 10 seconds. The

Online LED will begin glowing in a cyclical order: GREEN-
AMBER-RED, indicating it is going into “Program mode”.

3. The Back-UPS will then indicate the current

sensitivity, as shown in the

Transfer Voltage and Sensitivity

Adjustment

table below.

4. To select the LOW sensitivity setting, press the ON/OFF

push button until the LED begins
flashing GREEN.

5. To select the MEDIUM sensitivity setting, press the ON/

OFF push button until the LED begins flashing RED.

6. To select the HIGH sensitivity setting, press the ON/OFF

push button until the LED begins
flashing AMBER.

7. To exit Programming mode, once sensitivity is set, wait
