Optional Installation
These connections are optional. Your UPS will function properly without these connections.
1
USB and RS-232 Serial
Communications
Use the included USB cable (see
1A
) or
DB9 serial cable (see
1B
) 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.
2
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
2A
) to a user-
supplied normally closed or normally open
switch according to the circuit diagram
(see
2B
). The EPO port is not a phone
line surge suppressor; do not connect a
phone line to this port.
