5.1.2 Rack-Mount UPS Installation
When using the GXT2 in a rack-mount configuration, the UPS must be supported by a slide kit, fixed
rails or a shelf.
When using the optional Adjustable Rack Mount Kit, you will use the following instructions. The fig-
ures accompanying 5.1.3 - Installing the Adjustable Rack-Mount Kit—Sold Separately shows
the positioning of the rack-mounting brackets. Liebert recommends taking the internal batteries out
of the UPS during rack installation. This will make the UPS cabinet lighter and easier to handle.

where you want to mount the UPS or battery cabinet.
