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.
