Contact Tripp Lite for information about replacement batteries. Battery replacement should be performed only by qualified service personnel. The batteries are hot-swappable: it is not necessary to turn off or disconnect the UPS and its connected load to replace the UPS's batteries. However, when it is convenient to do so, service personnel may simplify the replacement procedure by turning power off at the UPS outlets by pressing the OFF switch to and disconnecting the UPS's power cord from the wall outlet. When replacing the batteries on a SU1000RTXL2U, SU1000RTXL2UHV or SUINT1000RTXL2U, qualified service personnel should refer to "Battery Warnings" in the Safety section and follow this procedure: 1) Place the UPS horizontal with the Control Panel on the right side. 2) Remove both snap-on cover panels (A). 3) Unscrew and remove rack handle plates (B) on either side of the UPS. 4) Disconnect the microprocessor circuit board plug (C) located on the right side of the UPS. 5) Disconnect battery connectors (D). Note: while batteries are disconnected, the UPS will not provide battery backup in the event of a power outage. 6) Unscrew and remove the battery retaining bracket (E). 7) Grasp pull-tab and pull out sliding battery tray (F). 8) Make a detailed sketch of the batteries and the polarity, color and connection of all cables. Disconnect used batteries and dispose of them properly. Connect replacement batteries in exactly the way the original batteries were connected. Note: Small sparks arcing between battery connectors during battery replacement are normal. Reassemble the UPS by reversing steps 1-7. Note: you may not receive full runtime until your new batteries have fully charged. D C F A E B SU1000RTXL2U shown 12
