NOTE

• When the Liebert

GXT3

™

is installed in a rack, it must be supported by a shelf, fixed

rails or slide rails on each side. The factory-supplied rack mount handles cannot sup-

port 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.
