DIN rail clamps, control panel installation
All CPUs, SMs, CMs and CPs can be installed on the 35 mm 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.
