Installation and Configuration

3. Install the rear member of each bracket assembly
into the rack enclosure with two (2) M5 screws
provided in this kit (see figure at right). The return
flanges on the bracket assembly fit to the inside of
rack mounting rails. Insert screws loosely (finger-
tight) into the top and bottom holes of the return
flange on the rear member. Extend the bracket
assembly by sliding the front member forward until
it touches the front rack mounting rail. Insert two
(2) M5 screws loosely (finger-tight) into the top and
bottom holes of the return flange on each front
member. Make sure that the bracket assemblies
are at the same mounting height on all four (4) rack
mounting rails.
4. Get eight (8) M4 screws and eight (8) M4 nuts from
the hardware pack in this kit. Each nut has a
locking, nylon insert that begins gripping the screw
when it is halfway tight. Make sure to tighten the
nut and screw completely to ensure locking action.
Fasten the rear member and the front member
together using (4) screws and (4) nuts per bracket
assembly as shown in at right. For maximum
support, insert fasteners for each bracket assembly
as far apart as possible, depending on rack depth,
while still joining both members (see figures at
right). Check alignment of bracket assemblies and
TIGHTEN ALL SCREWS FROM Steps 2 and 3.
5. Prepare the UPS or battery cabinet (the
“equipment”) for rack mounting by following
instructions in the equipment’s user manual. The
equipment may require additional parts to be
added or parts to be removed for rack mounting.
After it is prepared, lay the equipment in rack-
mounting position. Fasten the inner members from
Step 1 to the equipment on both sides as shown at
right with seven (7) M4 screws provided in the kit.
Make sure retaining latch is near the rear of the
equipment as shown (see figure below right).
6. Open the grease packet provided in the kit. Apply a
bead of grease 25mm (1") long at four (4) 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.

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 GXT2-
6000RTL630 weighs 151 lb (67kg). For the
battery cabinet’s weight, see the unit’s user
manual.
