III. Installing and fixing racks
As shown in Figure 8-26, follow these steps to install and fix a rack:
1) Clean the floor and rack surface.
2) Align the rack installation holes with the corresponding expansion bolts and fix
the rack on the floor with bolts, spring washers and big flat washers.
3) Torque the bolts to 45 Nm. Note to do that diagonally to reduce stress between
the bolts and the rack and facilitate rack adjustment during installation.
Repeat these steps to install other racks.
1) M12×60 bolt
3) Φ12 big flat washer
5) Expansion nut
7) Retaining bolt (middle)

I. Installing T-shape nuts
Before installing a pair of rails, put T-shape nuts into their downside troughs, four for each rail.
Two of these nuts are used for fixing the rail, and another two are for fixing the floor pallet
assemblies. This must be done before installing rails; after that, you are unable to install the
nuts.
2) Φ12 spring washer
4) Expansion tube
6) Height-retaining bolt (both sides)
8) Height silkscreen of antistatic floor
