• 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
field 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 field 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 2.
2.
Pull the two bottom mounting clips outward from
the controller to the extended position (Figure 3).
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), 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 bot-
tom mounting clips out to the extended position and care-
fully 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 3.
2.
Mark the mounting hole locations on the wall using
the dimensions in Figure 3 and one of the mount
positions shown in Figure 2. 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.

Wiring
Observe the following guidelines when wiring a controller:
CAUTION
Risk of Electric Shock
Disconnect the power supply before making electrical
connections to avoid electric shock.
