REPLACING THE BATTERY MODULE
This UPS has an easy to replace, hot-swappable battery module. Replacement is a safe procedure, isolated from electrical haz-
ards. You may leave the UPS and connected equipment on for the following procedure. See your dealer or contact APC for in-
formation on replacement battery modules.
Once the battery is disconnected, the loads are not protected from power outages.
REMOVING THE FRONT BEZEL AND BATTERY MODULE
The battery module is accessible from the front of the UPS. This procedure requires a Phillips or
straight head screwdriver.
1. Remove the front bezel. Use both hands and grasp the finger clips on either side of the bezel .
Pull it toward you. The bezel will unsnap from the top of the UPS. (Note the ribbon cable that
attaches the front panel PCB to the main PCB . Do Not remove this cable.) The bezel will still
be engaged at the bottom of the unit. Carefully disengage the bezel from the hooks at the bottom
of the UPS.
2. Set the bezel with the ribbon cable attached on top of the UPS. You will reinstall the bezel later.
3. Use a screwdriver to remove the two screws located at the top corners of the face plate .
Set the screws aside in a safe place. You will replace them later.
4. Open the face plate to access the battery inside the battery compartment.
1500VA Model
Be careful during this step-the battery module is heavy.
1. The battery module is connected to the UPS by way of cables inside the battery module com-
partment.
To remove the battery module from the UPS, grasp the clear plastic label and pull the battery
module toward you.
2. Pull the battery module out of the compartment so that the back of the module is flush with the
outer edges of the UPS.
3. Disconnect the battery module connector .
