Battery Replacement Procedure

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

Remove the front bezel by grasping the finger clips on the side of the bezel and carefully loosening the four (4) snaps. Skip to step 3.

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

3.Use a screwdriver or a coin to remove the two (2) battery door screws and open the door.

4. Disconnect the front battery pack:

grip the white cord on the front set of batteries and pull firmly to disconnect the connector.

5.Pull the front battery out of the UPS by pulling on the clear label, not the white cord.

Notes:

Be careful removing the batteries - they are heavy. Support the bottom of the batteries as

you remove them. There are four sets of batteries.

6.Reach into the battery compartment and grasp the white cord on the other battery connector. Pull firmly to disconnect the connector and remove the rear set of batteries.

7.Slide the rear set of new batteries into the unit.

Hold the battery pack so that the leads are on the right-hand side. Slide the battery pack into the UPS.

Press the gray connector into the plug at the bottom and to the right of the battery compartment. Tuck the white cord (that serves as a handle for the connector) neatly to the side.

8.Slide the front set of batteries in, then guide the connector over the batteries and press firmly to connect it to the front connector of the battery compartment.

Notes:

Repeat steps 4 through 9 for the second set of batteries.

Small sparks at the battery connectors are normal during connection.

9.Close the battery door, replace the screws, and replace the front cover.

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.
