Are you Installing a 2-Meter Rail?
If not, you can skip this section and read on from the section entitled
Dimensioned Drawing for Fixing Holes.
If so, the 2-meter rail has to be prepared for installation.
Proceed as follows:
1. Shorten the rail to the required length.
2. Mark out:
– Four holes for fixing screws (for dimensions, see Figure 4-5 and
Table 4-1)
– A hole to take the fixing screw for the protective conductor.
3. Is the rail longer than 830 mm?
If so: You must make additional holes for more fixing screws to ensure the rail is
secure.Mark out these holes along the groove in the middle section of the rail
(see Figure 4-5). These additional holes should be at 500 mm intervals.
If not: No further steps must be taken.
4. Drill the marked holes to a diameter of 6.5
+0.2
mm for M6 screws.
5. Tighten the M6 screw to fix the protective conductor.
