Download the PowerAlert UPS monitoring software program appropriate for your operating system from www.tripplite.com and install it on your computer. SEE MANUAL FOR PROPER CONNECTION NORM DELAY EXTERNAL BATTERY • External Battery Connection (Select Models Only) Your UPS comes with a robust internal battery system; external batteries are only needed to extend runtime. Adding external batteries will increase recharge time as well as runtime. The illustration 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's 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 more than one external battery, set the Battery Charge Level Switch to the "EXTERNAL BATTERY" position. This will increase your UPS's charger output so the additional batteries charge faster. CAUTION! DO NOT set the Battery Charge Level Switch to the "EXTERNAL BATTERY" position without an external battery connected. There is a risk of damaging the UPS's internal battery system.
