9.1.1Internal Battery Replacement Procedures

1.Gently remove the front plastic bezel cover from the UPS.

2.Loosen and remove the four screws on the front battery door. Lay the battery door aside for reassembly.

Note: The 3000VA model includes a pull handle to remove this door. It has two built-in connectors that disconnect when servicing the battery. THIS HANDLE MUST BE REINSTALLED IN ORDER FOR THE UPS TO OPERATE IN BATTERY MODE.

3.Gently pull battery wiring out and disconnect the two slotted battery connectors.

4.Grasp the battery pack assembly, and pull it out of the front of the UPS.

5.Unpack the new battery assembly taking care not to destroy the packing. Compare new and old battery assemblies to make sure they are the same. If so, proceed with Step 6; otherwise STOP and contact your local dealer, Liebert representative, or the Liebert Worldwide Support Group.

6.Line up and slide in the new replacement battery pack.

7.Reconnect the two slotted battery connectors and gently push the battery wiring and battery pack assembly back into the UPS.

8.Reattach the front battery door with the four screws.

9.Reattach the front plastic bezel cover to the UPS.

NOTE

These are hot-swappable replacement batteries. However, caution should be exercised because during this procedure the load is unprotected from disturbances and power outages.
