6. If available, apply a bead of grease 1" (25mm) long at four
places inside the bottom, curved tracks of the front members
as shown below right. The grease will allow the equipment to
slide into the bracket assemblies more easily..
7. Insert the equipment, with inner members attached in Step 5, into the bracket assemblies by
inserting the top and bottom edges of the inner members into the top and bottom curved tracks of
the front members and sliding the equipment into the rack (see figure at right). Ends of inner
members are tapered to allow the rear of the equipment to be angled upward before insertion, if
space allows.
Then the rear, bottom edges of the inner members can be placed into the front edge of the bottom
tracks and the front of the equipment can be tipped up so they are level to insert the top edges of
the inner members before sliding the equipment into the rack (see figure above right). The equip-
ment should move smoothly into the bracket assemblies. If it does not, recheck the alignment of
the front and rear members from Steps 2 and 3.
8. Secure the front of the equipment to the rack mounting rails to prevent the equipment from
sliding out of position. If securing holes are provided on the front of the equipment that align with
the center holes on the return flange of the front members, you can use the four extra M5 screws
provided in the kit to secure the equipment. Otherwise, the equipment should be secured to the
front of the rack with four customer-supplied fasteners.

CAUTION
Lifting equipment into the rack may be a two-person
job, depending on the weight of the equipment.
Liebert
®
recommends taking the internal batteries
out of the UPS during rack installation. This will
make the UPS cabinet lighter and easier to handle.
The Liebert GXT3
™
weighs 151 lb. (67kg). For the
weight of the UPS, see Table 7; for the battery
cabinet’s weight, see Table 11.
Factory-supplied rack handles are not intended to be
used to lift the UPS. The handles are intended to be
used to slide the UPS into and out of the rack.
