Optional Connections
(continued)
USB and RS-232 Serial
Communications
Use the included USB cable (see ) and/or
DB9 serial cable (see ) to connect the
communication port of 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. Your UPS may feature
additional communications ports; these ports
may be connected to additional computers that
have PowerAlert Software installed. Consult
your PowerAlert manual for more information.
EPO Port Connection
This optional feature is only for those
applications that 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.
External Battery Connection
Check to ensure that the external batteries
you are connecting match the voltage listed
on your UPS's battery connector. All UPS
models come with a robust internal battery
system; select models feature connectors that
accept optional external battery packs (sold
separately from Tripp Lite) to provide
additional runtime. Adding external batteries
will increase recharge time as well as
runtime. See the battery pack owner's manual
for complete installation instructions. Make
sure 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.
