Tripp Lite SUINT3000LCD2U Owner s Manual for Single-Phase Rackmount On-line UP - Page 21

Optional Connections 4 External Battery Connection Check the Model Specific Accessories section under Overview for compatible battery packs and maximum quantities for your UPS system. Ensure that your battery pack matches the voltage listed next to your UPS battery connector. Adding external batteries will increase recharge time as well as runtime. See the battery pack owner's manual for complete installation and setup 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 4 power. Your model may differ. IMPORTANT! In order for the runtime-remaining LCD and the software information screens to accurately predict runtime with external battery packs connected, you must configure any connected packs using the front panel LCD or Tripp Lite's External Battery Configuration software. See Configuring External Battery Packs section under Operations. CAUTION: Do not open or mutilate batteries. Released material is harmful to the skin and eyes. It may be toxic. The following precautions should be observed when working on batteries: Determine if the battery is inadvertently grounded. If inadvertently grounded, remove the source from ground connection. Contact with any part of a grounded battery can result in electrical shock. The likelihood of such a shock can be reduced if grounds are removed during installation and maintenance. (This is applicable to equipment and remote battery supplies that do not have a grounded supply circuit.) 21
