C&D Technologies RS-2098 RDC Rack - Manual (Page 3)

5. Installing Support Rail(s): See Figure 5. Place support rail(s)
in location using supplied 3/8” bolt, washer, serrated strut nut
and finger tighten (see Detail C). Align support rails with “A”
dimension from rack assembly drawing (See Detail D) and
install rail covers. Note: An internal/external “star” washer is
used in place of the lock washer on the bottom tier or step for
grounding connection. Optional third rail should be installed at
this time.
For rack lengths greater than 20 ft, the rails come in two
sections and are to be joined with a rail splice kit (P/N
RE05149 (See Figure 6). The rail lengths have been sized
to ensure that the joint occurs near the middle of the span
between two frames.

6. Leveling: Check that the rack is level and square. Torque down
all bolts. First torque the cross brace bolts to 55-65 ft.-lb. [75-88
N-m], then torque the rail to frame bolts to 15-20 ft.-lbs [20-27
N-m]. Torque anchor bolts to manufacturer’s recommended
value.
This concludes the steps required to install a C&D Standard
Rack, please proceed to step 8 for cell installation or if you are
