Watch video sequence (https://support.industry.siemens.com/cs/ww/en/view/95886672)
The 30 mm I/O modules have a fastening point at the top and bottom. The 30 mm wide I/O
modules can also be side-fastened. When fastening them at the side, you must use the
supplied spacers.
Follow the steps below to mount a 30 mm wide I/O module:
1. Drill two fastening holes with 4.5 mm diameter spaced 149.6 mm apart.
2. Use the supplied spacers for side fastening of the I/O module on the top and bottom (on one
side adjacent to the fastening surface).
3. Fasten the I/O module with the screws to both fastening points (tightening torque 1.2 Nm).
