• Excessive humidity or contact with fluids
Plug the Back-UPS ES power cord directly
into a wall outlet; not into a surge protector
or power strip.
Connect Fax/Modem/Phone
Back-UPS ES protects a single
line (two-wire) fax, modem or
phone from surges when it is
connected through the
Back-UPS ES outlets as shown.
Connect Computer Cable
The supplied cable and software provide
automatic file saving and shutdown of the
operating system in the case of a sustained
power outage.
Connect the cable to the Comm Port of the
Back-UPS ES.
Connect the other
end of the cable to
the Comm port on
your computer. The
software will
automatically use
Comm Port 1 of your
computer.
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 PC, monitor, and one
other data-sensitive device (Zip
TM
drive, for example) into these
outlets.
These outlets provide protection from surges and are powered
whenever the Back-UPS ES is switched on. Plug your printer,
fax machine, scanner, or other peripherals that do not need
battery power during a power failure into these outlets.
