Installation Manual

Installing B68 Cabinets

Each cabinet is equipped with four sets of brackets for fixing floor pallets, two for each rail.

Figure 8-27shows a T-shape nut.

II. Leveling and fixing rails

Fix the rails on the rack with T-shape nuts, flat washers, spring washers and bolts M1220 as shown in Figure 8-28.

Caution:

Install rails in such a way that their protective sides are outward as shown in Figure 8-28.

Follow these steps to level and fix the rails:

1)First screw the bolts M1220 with spring washers and flat washers. Do not tighten the screws at this time, just make sure they will not drop down.

2)Insert the bolts into the rack holes in sequence.

3)Measure (in both transverse and longitudinal directions) the slide rail segments with a horizontal ruler to check that the bubble in the horizontal ruler is in the middle. If the slide rail is horizontal, tighten the bolts in sequence and measure horizontality again. If not, adjust by adding or reducing washers. See Figure 8-29.

4)The installed slide rails must meet these requirements:

zIndividual slide rail segments must be horizontal in longitudinal direction.

zTwo parallel slide rails must be horizontal in transverse direction.

zThe distance between the central lines of two parallel slide rails should be 720mm!1mm.

When joining multiple slide rail segments, adjust them using a straight thread, making sure that they form a straight line. No gap or height difference is allowed between the joints.
