Optional Installation
These connections are optional. Your UPS will function
properly without these connections.
USB and RS-232 Serial
Communications
Use the included USB cable (see ) and DB9 serial
cable (see ) to connect the communication port on
your computer to the communication port of your
UPS. Install on your computer the Tripp Lite
PowerAlert Software appropriate to your computer’s
operating 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 sup-
pressor; do not connect a phone line to this port.
