DIN Rail Mount Applications

Mounting the field controller horizontal on 35 mm DIN rail
is the preferred mounting method.
To mount a controller on 35 mm DIN rail:
1. Securely mount a 20 cm (8 in.) or longer section of
35 mm DIN rail horizontal and centered in the
appropriate location so that the controller mounts in
the horizontal position shown in
2. Pull the two bottom mounting clips outward from the
controller to the extended position.
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(see Figure
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

To mount a field controller directly on a wall or other flat
vertical surface:
1. Pull the two bottom mounting clips outward and
ensure they are locked in the extended position as
shown in Figure 2.
2. Mark the mounting hole locations on the wall using
the dimensions in Figure 2
positions shown in Figure

2), and position the controller
and one of the mount
1. 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 overtighten the mounting screws.
Overtightening the screws may damage
the mounting clips.
