Tripp Lite AGSM751SRM1U Optional Installation, USB and RS-232 Serial Communications all models

Optional Installation

These connections are optional. Your UPS will function properly without these connections. Note: SMX3000XLRT2U shown in all diagrams.

1USB and RS-232 Serial Communications (all models)

Use the included USB cable (see 1a ) and/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. 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.

2EPO Port Connection (all models)

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.

3External Battery Connection (select models)

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 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.

*See Specifications section for battery packs available for your specific UPS model.
