Holes For Mounting The 2-M Profile Rail - Siemens SIMATIC S7-300 Hardware And Installation Manual

Installation
Preparing the 2-m profile rail for mounting
1. Cut the 2-m profile 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 profile 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 profile rail
(see the Figure below). The pitch should be approx. 500 mm.
4. Drill the marked holes to a diameter of 6.5
5. Mount an M6 bolt for fixing the ground conductor.
