Installation and Configuration

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.

! CAUTION

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. For the weight of the UPS, see Table 7; for the battery cabinet’s weight, see Table 10.

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 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 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.

5.2External 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

The external battery cabinet(s) are heavy (see 12.0 - Specifications). Take proper precautions when lifting them.
