Tripp Lite 2POSTRMKITWM USB and RS-232 Serial Communications all models, Optional Installation

Optional Installation

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

1USB and RS-232 Serial

Communications (all models)

Use the included USB cable (see 1a ) and/or DB9 seri- al cable (see 1b ) to connect the UPS to a Media Center PC, home automation system or server. Install the Tripp Lite PowerAlert Software appropriate to your equip- ment's operating system. Your UPS may feature addi- tional communication ports; these ports may be con- nected to additional home entertainment or home automation PCs that have PowerAlert Software installed. Consult your PowerAlert manual for more information.

2EPO Port Connection (all models)

This optional feature is only for those applications that require connection to a home automation/home security Emergency Power Off (EPO) circuit. When the UPS is connected to this circuit, it enables emer- gency 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.

3External Battery Connection

(select models only)

Your UPS comes with a robust internal battery sys- tem; external batteries are needed only to extend run- time. Adding external batteries will increase recharge time as well as runtime.

The illustration (see 3a ) shows the location of your UPS’s External Battery Connector, where you will insert the battery pack cable. Complete installation instructions for your battery pack appear in the battery pack owner’s manual. Make sure that 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.

If you connect any external batteries, set the Battery Charge Level Switch (see 3b ) to the down position. This will increase your UPS’s charger output so that the additional batteries charge faster. Note: The switch to the right of the Battery Charge Level Switch is inactive and will not affect UPS operation regardless of its position.

Caution! DO NOT set the Battery Charge Level Switch to the down position without an external battery connected. There is a risk of damaging the UPS’s internal battery system.
