the front panel approximately 1/8 in. (3
mm) and tilting the top away from the unit.
Remove the screw from the inside cover
and remove the inside cover by lifting it
away from the UPS. Squeeze both sides of
the plug to unplug the battery pack.
Insert the new battery pack into the UPS
with the molded cover at the top. Rest the
wires at the front and to the left of the
battery. Once the battery pack is in place,
insert the plug and refit the inside cover
with the screw. Attach the front cover.
