Emerson Liebert GXT3-5000RT230 User Manual page 19

The adjustable rack-mounting brackets (Part#: RMKIT18-32) feature retaining latches to prevent
users from inadvertently sliding the UPS or battery cabinet out of the rack.
To install the rack mount brackets:
1. Unpack two (2) rack-mounting bracket assemblies and
mounting hardware from this kit. Bracket assemblies are
interchangeable between left-hand or right-hand.
Remove inner member of each bracket assembly as shown
at right by extending it to its outermost position, depress-
ing the retaining latch and then pulling the inner member
out of the bracket assembly.
2. Determine the height position inside the rack enclosure
where you want to mount the UPS or battery cabinet.
CAUTION
!
Reduce the risk of tipping the rack enclosure by
placing the UPS or battery cabinet in the lowest
possible rack position.
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 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 eight (8)
M4 screws provided in the kit. Make sure retaining latch is
near the rear of the equipment as shown (see figure at
right).
