11.1.1 Internal Battery Replacement

! CAUTION

A battery can present a risk of electrical shock and high short circuit current. Observe the following precautions before replacing the batteries:

•Remove rings, watches and other metal objects.

•Use a Phillips (cross-head) screwdriver with insulated grips.

•Do not lay tools or other metal objects on top of the batteries.

•If the battery replacement kit is damaged in any way or shows signs of leakage, contact your local dealer or Liebert representative immediately.

•Do not dispose of batteries in a fire. The batteries may explode.

•Do not open or mutilate batteries. Released electrolyte is harmful to the skin and eyes. It is toxic.

1.Remove the 3U battery access panel on the front of the UPS by loosening the two captive screws located between the bezels (see illustration at right).

2.Once the captive screws are loosened, tip the panel forward and lift to remove it from the main cabinet.

3.Use a Phillips (cross-head) screwdriver to remove the screw in the battery retaining bracket on each battery pack (see illustration at right). Remove the retaining brackets.

4.Disconnect the battery connectors in the front of each battery pack.

5.Lift the internal connector out of the way and slide the battery out of the UPS. Support the weight of the battery to prevent it from falling.

6.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 7; otherwise STOP and contact your local dealer, Liebert representative or the Liebert Worldwide Support Group.

7.Line up and slide in the new replacement battery pack while holding the internal connector out of the way.

8.Reconnect the electrical connections for each battery pack.

9.Install the battery retaining brackets using the Phillips removed earlier.

10.Install the battery access panel and tighten the captive screws.

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.
