these ports may also be connected to additional
computers which have PowerAlert Software installed.
Consult your PowerAlert manual for more information.

RS-232 Serial Communications
If your computer is equipped with a DB9 serial port,
use the included serial cable to connect the DB9 port of
your computer to the DB9 port of your UPS. Install on
your computer the Tripp Lite PowerAlert Software
appropriate to your computer’s operating system. Your
UPS may feature additional communications ports;
these ports may also be connected to additional

Consult your PowerAlert manual for more information.

External Battery Connection
(select models)
Your UPS comes with a robust internal battery system;
external batteries are only needed to extend runtime.
Adding external batteries will increase recharge time as
well as runtime.
The illustration (see
3a
) shows the location of your
UPS’s External Battery Connector, where you will insert
the battery pack cable. Complete installation instructions for
your battery pack appear in the battery pack’s owner’s
manual. Make sure that cables are fully inserted into
their connectors. Small sparks may result during battery
connection; this is normal.
Do not connect or disconnect battery packs when the
UPS is running on battery power.
If you connect any external batteries, set the Battery
Charge Level Switch (see
3b
) to the up position. This
will increase your UPS’s charger output so the
additional batteries charge faster. Note: the switch to
the right of the Battery Charge Level Switch is inactive
and will not affect UPS operation regardless of its
position.
CAUTION! DO NOT set the Battery Charge Level
Switch to the up position without an external
battery connected. There is a risk of damaging the
UPS’s internal battery system.
