Determine Your Next Step: Use the following to determine your next step:
v If the rack is being attached to a concrete (non-raised) floor, proceed to “Attach the Rack to a Concrete
(Non-Raised) Floor.”
v
If the rack is being attached to a raised floor, proceed to “Attaching the Rack to a Short or Long Raised
Floor” on page 111.
Attach the Rack to a Concrete (Non-Raised) Floor: Use this procedure to attach the rack to a concrete
(non-raised) floor.
Attention: It is the customer’s responsibility to ensure the following steps are completed before the
service representative performs the tie-down procedure.
Note: The customer should obtain the service of a qualified structural engineer to determine appropriate
anchoring of the mounting plates. A minimum of three anchor bolts for each mounting plate must be
used to secure the plates to the concrete floor. Because some of the drilled holes may be aligned
with concrete reinforcement rods below the surface of the concrete floor, additional holes must be
drilled. Each mounting plate must have at least three usable holes, two that are on opposite sides
and opposite ends of each other, and one hole at the center. The mounting plates should be able to
withstand 2500 pounds pulling force on each end.
