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.
