2.4.2 Rack Installation
To install a Liebert GXT3 rack/tower UPS in a rack:
1. Unpack the two bracket assemblies and mounting hardware from the rack-mounting kit
(P/N: RMKIT18-32).
Bracket assembly includes inner member and front and rear members. They are interchangeable
between left-hand or right-hand. Mounting hardware includes M4 screws and M5 screws.
2. Remove inner member of each bracket assembly by extending it to its outermost position,
depressing the retaining latch and then pulling inner member from bracket assembly (see
Figure 11).

screws (see Figure 12).

NOTE
• When the Liebert GXT3 is installed in a rack, it must be supported by a shelf, brackets
or slide rails on each side. The factory-supplied ears cannot support the weight of the
UPS. They are used to move the UPS into and out of the rack and attach the UPS to the
rack.
• Mounting hardware and slide rails are sold separately. Contact your local Emerson
representative for these options and any assistance.
• GXT3-1000MT120 cannot be installed in a rack. The unit is a minitower only.
!
CAUTION
Reduce the risk of tipping the rack by installing the Liebert GXT3 as low as possible in the
rack.
