USB Communications
Use the included USB cable to connect the USB
port of your computer to the USB 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 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 computers which have
PowerAlert Software installed. 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 ) 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 an
y external batteries, set the
Battery Charge Level Switch (see ) 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 con-
nected. There is a risk of damaging the UPS’s internal battery system.

EPO Port Connection
This optional feature is only for those applications
which require connection to a facility’s
Emergency Power Off (EPO) circuit. When the UPS
is connected to this circuit, it enables emergency
shutdown of the UPS's inverter.
Using the cable provided, connect the EPO port of
your UPS (see ) to a user-supplied normally
closed or normally open switch according to the
circuit diagram (see ). The EPO port is not a
phone line surge suppressor; do not connect a
phone line to this port.
