SAN512B-6 Installation, Service, and User Guide
Note: You must use a minimum of two anchor bolts for each rack-mounting
plate to attach it to the concrete floor. Because some of the holes in the
rack-mounting plates might align with concrete reinforcement rods below the
surface of the concrete, some of the rack-mounting plate holes might not be
suitable.
17. For each rack-mounting plate, select at least two suitable holes. Select holes as
close to the threaded holes as possible. Be sure that the holes you select at the
rear of the rack are accessible. Drill the selected holes (two for each
rack-mounting plate) in the concrete floor.
18. Drill pass-through holes in the raised-floor panel at the location of the four
rack-mounting bolts.
19. Position the front rack-mounting plate within the marked area.
20. Using anchor bolts, attach the front rack-mounting plate to the concrete floor.
Do not use the four plastic isolator bushings.
21. Position the rack on the raised-floor panel over the front rack-mounting plate.
22. Position the rear rack-mounting plate within the marked area.
23. Using anchor bolts, attach the rear rack-mounting plate to the concrete floor.
24. Insert each of the rack-mounting bolts through a flat washer, a plastic isolator
bushing, a thick washer, and through a leveling foot.
25. Align the four rack-mounting bolts with the four tapped holes in the two
mounting plates and turn the bolts 3–4 rotations.
26. Tighten the locking screw on each caster.
27. Adjust the leveling feet downward, as needed, until the rack is level. See
Figure 67. When the rack is level, tighten the jam nuts against the base by
turning the jam nut clockwise (toward the bottom of the rack). Torque the
four bolts to 54–67 nm (40–50 ft-lbs).
