Installation and Configuration
3.Install the rear member of each bracket assembly into the rack enclosure with two (2) M5 screws provided in this kit (see figure at right). The return flanges on the bracket assembly fit to the inside of rack mounting rails. Insert screws loosely (finger- tight) into the top and bottom holes of the return flange on the rear member. Extend the bracket assembly by sliding the front member forward until it touches the front rack mounting rail. Insert two
(2) M5 screws loosely
4.Get eight (8) M4 screws and eight (8) M4 nuts from the hardware pack in this kit. Each nut has a locking, nylon insert that begins gripping the screw when it is halfway tight. Make sure to tighten the nut and screw completely to ensure locking action. Fasten the rear member and the front member together using (4) screws and (4) nuts per bracket assembly as shown in at right. For maximum support, insert fasteners for each bracket assembly as far apart as possible, depending on rack depth, while still joining both members (see figures at right). Check alignment of bracket assemblies and TIGHTEN ALL SCREWS FROM Steps 2 and 3.
5.Prepare the UPS or battery cabinet (the “equipment”) for rack mounting by following instructions in the equipment’s user manual. The equipment may require additional parts to be added or parts to be removed for rack mounting. After it is prepared, lay the equipment in rack- mounting position. Fasten the inner members from Step 1 to the equipment on both sides as shown at right with seven (7) M4 screws provided in the kit. Make sure retaining latch is near the rear of the equipment as shown (see figure below right).
6.Open the grease packet provided in the kit. 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-
6.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 GXT2- 6000RTL630 weighs 151 lb (67kg). For the battery cabinet’s weight, see the unit’s user manual.
