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, 
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 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).
!
CAUTION
Reduce the risk of tipping the rack enclosure by 
placing the UPS or battery cabinet in the lowest 
possible rack position.
