Caution:
The spanners used to level the cabinets should be installed between the insulation
plates and the guide rails. If you install the spanners between the insulation plates and

Place a horizontal ruler in the two orthogonal directions on the top of the
cabinets to check levelness.
If any cabinet is out of levelness, adjust the levelness by using shims under
the insulation plate, as shown in Figure B-46.
Align all the cabinets. The cabinets should be close to the adjacent
equipment. They must be in a straight line on the primary walkway side.
