Emerson GXT3 230V user manual To install the rack mount brackets

Installation and Configuration

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

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).
