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.
