6.1.2 Installing the Adjustable Rack-Mount Kit—Sold Separately
This kit contains parts needed to mount several different models of UPS and external battery cabi-
nets into EIA310-D standard four-post racks that are 18-32" deep (457-813mm). The weight limit per
pair of adjustable rack-mounting brackets is 200 pounds (91 kg).
Liebert rack-mount bracket kit, part # RMKIT18-32, includes:
Tools needed for installation are:
• one Phillips screwdriver
• one 7mm wrench
The adjustable rack-mounting brackets 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
in at right by extending it to its outermost position,
depressing 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.
3. Install the rear member of each bracket assembly into 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 top and bottom holes of the return flange on each
front member. Make sure bracket assemblies are at the
same mounting height on all four (4) rack mounting rails.
