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 1a 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 1b 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. 3 External Battery Connection (Select Models Only) Your UPS comes with a robust internal battery system; external batteries are needed only to extend 2a runtime. 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 A , 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 2b is running on battery power. If you connect any external batteries, set the Battery Charge Level Switches (see 3b ) to the down position (High Charge Rate - External Battery). This will increase A your UPS's charger output so that the additional batteries charge faster. CAUTION! DO NOT set the Battery Charge Level Switches to the down position (High Charge Rate - External Battery) without an external battery 3a connected. There is a risk of damaging the UPS's internal battery system. CAUTION! When an external battery pack is connected, make sure the AC load does not exceed the nameplate rating. Some models are derated when an external battery pack is connected. 3b 7 201203014 93-2757.indd 7 4-5 3/15/2012 5:03:45 PM
