Mounting
Lock the modules
together using the
connecting clips
3-6
After the modules have been plugged together lock them in place using
the two connecting clips provided with each EXM module so that the
modules cannot be twisted or moved apart. Proceed as follows:
1. Insert a connecting clip from top between the two modules to be
clipped together until the bent clip ends come into contact with the
housing cover of the modules.
2. Align the connecting clip, so that the angled section of the clip is
located above a grid hole of the module housing cover. The first bent
clip end should be located above the 5
module.

3. Then press downwards on the connecting clip at the two ends which
are bent at right angles until they latch into place.
4. Repeat steps 1 to 3 at the lower side of the modules to be latched
together.
