Emerson Dual Conversion Online UPS GXT3-6000RT208 User Manual

6. If available, apply a bead of grease 1" (25mm) long at four 

places inside the bottom, curved tracks of the front members 

as shown below right. The grease will allow the equipment to 

slide into the bracket assemblies more easily..

7. Insert the equipment, with inner members attached in Step 5, into the bracket assemblies by 

inserting the top and bottom edges of the inner members into the top and bottom curved tracks of 

the front members and sliding the equipment into the rack (see figure at right). Ends of inner 

members are tapered to allow the rear of the equipment to be angled upward before insertion, if 

space allows.
Then the rear, bottom edges of the inner members can be placed into the front edge of the bottom 

tracks and the front of the equipment can be tipped up so they are level to insert the top edges of 

the inner members before sliding the equipment into the rack (see figure above right). The equip-

ment should move smoothly into the bracket assemblies. If it does not, recheck the alignment of 

the front and rear members from Steps 2 and 3.

8. Secure the front of the equipment to the rack mounting rails to prevent the equipment from 

sliding out of position. If securing holes are provided on the front of the equipment that align with 

the center holes on the return flange of the front members, you can use the four extra M5 screws 

provided in the kit to secure the equipment. Otherwise, the equipment should be secured to the 

front of the rack with four customer-supplied fasteners.

Lifting equipment into the rack may be a two-person 

job, depending on the weight of the equipment. 

Liebert

®

 recommends taking the internal batteries 

out of the UPS during rack installation. This will 

make the UPS cabinet lighter and easier to handle. 

The Liebert GXT3

weight of the UPS, see Table 7; for the battery 

cabinet’s weight, see Table 11.
Factory-supplied rack handles are not intended to be
