Installing the mounting rail
The mounting rail with 500 mm length must be cut to length according to your
requirements.
To install the mounting rail with 500 mm length, follow these steps:
1. Drill the mounting holes for screws with 8 mm diameter.
We recommend that, after an initial distance of 12 mm, the mounting holes be provided at
regular intervals of 182 mm.
2. Fasten the mounting rail with the screws.

1. Insert a profile screw through the mounting point of the I/O device and in a groove of the
mounting rail.
2. Use the screwdriver to screw the I/O device to the mounting rail.
3. Align the I/O device on the mounting rail.
4. Insert a profile screw through the other mounting point of the I/O device and in the other
groove of the mounting rail.
5. Screw the I/O device to the mounting rail. The tightening torque is 1.5 Nm.
