Battery Replacement Procedure - 3U Rack Mount Units

1. Reach into the finger pull and open the front cover. Swing the cover open as shown.

2. Unhook the side of the cover from the chassis and lift it away to expose the battery door.

3. Use a flat-blade or Phillips screwdriver or a coin to remove the two battery door screws and

open the door.

4. Grasp the tab and gently pull the battery out of the UPS.

5. Disconnect the battery leads. Loosen the connectors by gently wiggling them while pulling

straight back from the battery connector.

6. Connect the battery leads to the new battery. Connect the red wire to the positive (+) terminal

and the black wire to the negative (–) terminal.

7. Slide the battery into the UPS.

8. Close the battery door, replace the battery compartment screws, and replace the front cover.

Notes:

Be careful removing the batteries - they are heavy.

Small sparks at the battery connectors are normal during connection.

Batteries must be recycled. Deliver the battery to an appropriate recycling facility or ship it to the

supplier in the new battery’s packing material. See the new battery instructions for more

information.
