A drilling with the diameter for the corresponding screwing (see Table 3, column 2) is sufficient for
the insertion of cables into a cabinet or a single walled housing. In this case the screw is locked
with the supplied locknut from the inside.
Transport lock
Remove the, on fan-motor base frame of spring isolators mounted transport lock (signed with red
point) according to Figure 72 below.
1. Remove nuts and bolts of position 1, 2 and 3
2. Remove z-shaped metal sheet (position 4)
3. Again fasten the nut of position 1, including the potential compensation wire
