the battery door aside for reassembly.

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.

UPS.

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.

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