• Provide for sufficient space around the controller for
cable and wire connections for easy cover removal
and good ventilation through the controller (50 mm
[2 in.] minimum on the top, bottom, and front of the
controller).
• Do not mount the controller on surfaces prone to
vibration, such as duct work.
• Do not mount the controller in areas where
electromagnetic emissions from other devices or wiring
can interfere with controller communication.
Observe these additional guidelines when mounting a
controller in a panel or enclosure:
• Mount the controller so that the enclosure walls do
not obstruct cover removal or ventilation through the
controller.
• Mount the controller so that the power transformer
and other devices do not radiate excessive heat to the
controller.
• Do not install the controller in an airtight enclosure.

DIN rail mount applications
Mounting the controller horizontal on 35 mm DIN rail is
the preferred mounting method.
To mount a field 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 desired
space so that the controller mounts in the horizontal
position shown in Figure 1.
2.
Pull the two bottom mounting clips outward from the
controller to the extended position (Figure 2).
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 2), 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
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 three mounting hole locations on the wall
using the dimensions in Figure 2 and one of the
mount positions shown in Figure 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 locations
marked in Figure 2, and insert appropriate wall
anchors in all of the mounting 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.
