4Connect external battery pack(s) to your UPS
Your UPS has no internal batteries and must be connected to at least one external battery pack to operate. Complete installation and mounting instructions for your battery pack(s) appear in the battery pack(s)’s owner’s manual. Make sure that connection cables are fully inserted into their connectors. Small sparks may result during battery pack connection; this is normal.
Your UPS will not operate unless connected to a charged external battery pack. Battery packs are fully charged prior to shipping. However, if your battery pack has been stored for an extended period, recharge its battery for 8 hours. To charge the battery pack, turn on the UPS’s and isolation transformer’s AC input breakers. Your UPS may not provide its full runtime if the battery pack is not fully charged.
Once the UPS is operating, it will charge its battery pack(s) automatically.
