bottom of the CPU are in the extended position.
Do not use a flat head screw.
Note
The type of screw will be determined by the material upon which it is mounted. You
should apply appropriate torque until the spring washer becomes flat. Avoid applying
excessive torque to the mounting screws. Do not use a flat head screw.
Note
Using DIN rail stops could be helpful if your CPU is in an environment with high vibration
potential or if the CPU has been installed vertically. Use an end bracket (8WA1 808 or
8WA1 805) on the DIN rail to ensure that the modules remain connected. If your system
is in a high-vibration environment, then panel-mounting the CPU will provide a greater
level of vibration protection.
Procedure
1. Install the DIN rail. Secure the rail to the mounting panel every 75 mm.
2. Ensure that the CPU and all S7-1200 equipment are disconnected from electrical
power.
3. Hook the CPU over the top of the DIN rail.
4. Pull out the DIN rail clip on the bottom of the CPU to allow the CPU to fit over the
rail.
5. Rotate the CPU down into position on the rail.
6. Push in the clips to latch the CPU to the rail.
