Installation and Configuration
Liebert® GXT3™14
6. If available, apply a bead of grease 25mm (1") long at four (4)
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 below right). The
equipment should move smoothly into the bracket assemblies. If it does not, recheck the
alignment of the front and rear members from Steps 2 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 (4) 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 (4) customer-supplied fasteners.
5.2 External Battery Cabinet Installation
Optional Liebert external battery cabinets may be connected to the UPS to provide additional battery
run time. External battery cabinets are designed to be placed on one side of the UPS or stacked
beneath the UPS. External battery cabinets can be used in either a rack-mount or tower
configuration.
!
CAUTION
Lifting equipment into the rack may be a two-person
job, depending on the weight of the equipment.
Emerson® recommends taking the internal batteries
out of the UPS during rack installation. This will
make the UPS cabinet lighter and easier to handle.
For the weight of the UPS, see Table 7; for the
battery cabinet’s weight, see Table 10.
Factory-supplied rack handles are not intended to be
used to lift the UPS. These are intended to be used to
slide the UPS into and out of the rack.
!
CAUTION
The external battery cabinet(s) are heavy (see 12.0 - Specifications). Take proper
precautions when lifting them.
