7.1Battery Charging, Storage

The batteries are valve-regulated, nonspillable, lead acid and must be kept charged to retain their design life. The Liebert PSI XR continuously charges the batteries when connected to the utility sup- ply, even while the UPS is switched Off.

If the Liebert PSI XR will be stored for an extended period, Emerson recommends connecting the UPS to input power for at least 8 hours every four to six months to keep the batteries charged.

Emerson recommends performing a monthly manual self-diagnostic test via the Web card or the front panel display.

7.2Internal Battery Replacement Procedure

NOTICE

This UPS is equipped with internal batteries that the user can replace without shutting down the UPS or connected loads (hot swappable). Caution must be exercised when replacing the batteries because the load is unprotected from power fluctuations and power failures.

To replace the batteries:

1.Remove the two screws on the left side of the front bezel.

2.Pull the front bezel off the UPS.

3.Remove the screw on the battery connector holder.

4.Remove the two screws on the battery bracket.

5.Disconnect the two slotted, red/gray and black battery connectors.

6.Grasp the battery pack assembly by the handle and pull it out of the front of the UPS.

7.Unpack the new battery assembly, taking care not to destroy the packing.

8.Compare the new and old battery assemblies to make sure they are the same. If so, proceed with replacement. If they are different, STOP and contact your local dealer, local Emerson representative or Channel Support Applications.

9.Slide the new battery pack into the UPS.

10.Reattach the battery bracket with the two screws.

11.Reconnect the slotted, red/gray and black battery connectors.

12.Reinsert the screw on the battery connector holder.

13.Reattach the front bezel.
