Surge Protection
These outlets provide full-time protection from surges even if the
Back-UPS ES is switched OFF. Plug your printer, fax machine,
scanner, or other peripherals that do not need battery power into these
outlets.
Battery Back-up + 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 the outlets.
Press the ON/OFF switch turn the unit ON.
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.
Install the PowerChute Personal Edition software.
Place the PowerChute CD into the computer and following the
