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 ) and/or DB9 serial cable (see 1b ) to connect the c o m m u n i c a t i o n port on your computer to the communication port of your UPS. Install on your computer the Tripp 1a 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 1b 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 3 port. External Battery Connection Your UPS comes with a robust internal battery system; external batteries are needed only to extend runtime. Adding external batteries will increase 2a recharge time as well as runtime. The illustration (see 3a ) shows the location of your 4-5 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. 2b 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 Switches (see 3b ) to the down position. This will increase 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 without an external battery connected. There is a risk of damaging the 3a UPS's internal battery system. 3b 6
