DIN rail mounting clips
All CPUs, SMs, CMs and CPs can be installed on the DIN rail in the cabinet. Use the pull-out
DIN rail mounting clips to secure the device to the rail. These mounting clips also lock into
place when they are extended to allow the device to be installed in a switching panel. The
inner dimension of the hole for the DIN rail mounting clips is 4.3 mm.
