Emerson Dual Conversion Online UPS GXT3-6000RT208 User Manual

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 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.

3. Install the rear member of each bracket assembly into the 

rack enclosure with two 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 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 M4 screws and eight 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 four screws and four 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 eight M4 

screws provided in the kit. Make sure retaining latch is 

near the rear of the equipment as shown (see figure at 

right).

Reduce the risk of tipping the rack enclosure by 

placing the UPS or battery cabinet in the lowest 

possible rack position.
