1. Cut the 2 m rail to the required length.
2. Mark out:
– four bores for the fixing screws (for dimensions refer to "Dimensions for
fixing holes")
– one hole for the protective conductor bolt.
3. If the length of your rail exceeds 830 mm, you must stabilize it by providing
additional holes for fixing it with more screws.
Mark out these holes along the groove in the middle section of the rail (see the
Figure below). The pitch should be approx. 500 mm.
4. Drill the marked holes to a diameter of 6.5
+0.2
mm for M6 screws.
5. Attach an M6 screw for fixing the ground conductor.
