USB and RS-232 Serial Communications

Optional Installation

These connections are optional. Your UPS will function properly without these connections.

1USB and RS-232 Serial

Communications

Use the included USB cable (see 1a ) and/or DB9 serial cable (see 1b ) to connect the communication port on your equipment to the communication port of your UPS. Install on your equipment the Tripp Lite PowerAlert Software appropriate to your equipment’s operating system. Consult your PowerAlert manual for more information.

2EPO 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 sup- pressor; do not connect a phone line to this port.
