REPLACING THE BATTERY PACK
This UPS has an easy to replace, hot-swappable battery pack. Replacement is a safe procedure, iso-
lated from electrical hazards. You may leave the UPS and connected equipment on while replacing
the battery. See your dealer or contact APC for information on replacement battery packs. This pro-
cedure is used in both Tower and Rack Mount configurations.
Once the battery is disconnected, the loads are not protected from power outages.

EMOVE AND REINSTALL THE BATTERY PACK
Be careful during removal and replacement of the battery pack; it is heavy.
Remove Battery
1. Remove front bezel and the battery door if
they are attached. (See the instructions in
the Installation section of this manual to
remove the battery door and front bezel.)
2. If the battery is connected, disconnect the
battery by pulling on the connector firmly.
3. Grasp the battery pack and slide it out of the
