the above figures.
• The DIN rail channel and the mounting clips are
shown in an extended position.
DIN rail mount applications
About this task:
To mount a CGM controller horizontally on a 35 mm DIN
rail (recommended method), complete the following
steps:
1. Securely mount a 20 cm (8 in.) or longer section
of 35 mm DIN rail horizontal and centered in the
desired space so that the controller mounts in the
horizontal position.
2. Pull the two bottom mounting clips outward from
the controller to the extended position (Figure 3 or
Figure 4).
3. Hang the controller on the DIN rail by the hooks at
the top of the (DIN rail) channel on the back of the
controller (Figure 3 or Figure 4), and position the
controller snugly against the DIN rail.
4. Push the bottom mounting clips inward (up) to
secure the controller on the DIN rail. To remove
the controller from the DIN rail, pull the bottom
mounting clips out to the extended position and
carefully lift the controller off the DIN rail.
Wall mount applications
About this task:
To mount a CGM controller directly on a wall or other flat
vertical surface, complete the following steps:
1. Pull the two bottom mounting clips outward and
ensure they are locked in the extended position as
shown in Figure 3 or Figure 4.
2. Determine the proper mounting position the
expansion module will be installed. Mark the
mounting hole locations on the wall using the
dimensions for the controller listed in Mounting
features and dimensions, or hold the controller up
to the wall or surface in a proper mount position
and mark the hole locations through the mounting
clips.
3. Drill holes in the wall or surface at the marked
locations, and insert appropriate wall anchors in the
holes (if necessary).
4. Hold the controller in place, and insert the screws
through the mounting clips and into the holes (or
anchors). Carefully tighten all of the screws.
Important: Do not over-tighten the mounting
screws. Over-tightening the screws may
damage the mounting clips.
