Wall Mount Applications; Din Rail Mount Applications - Johnson Controls IOM1711 Installation Manual

• 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 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 bottom mounting clip outward from
the controller to the extended position as
shown in 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 clip inward (up) to
secure the controller on the DIN rail.
To remove the controller from the DIN rail,
pull the bottom mounting clip out to the
extended position and carefully lift the con-
troller off the DIN rail.

Wall mount applications

To mount a field controller directly on a wall or
other flat vertical surface:
1. Pull the bottom mounting clip outward and
ensure it is locked in the extended position as
shown in Figure 3.
2. Position the controller in a proper mounting
position shown in Figure 2 and mark the
mounting hole locations on the wall or surface
using the dimensions shown in Figure 3. Or,
hold the controller up to the wall or surface in
a proper mounting 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 wall anchors). Carefully tighten all of
the screws.
Important: Do not overtighten the
mounting screws. Overtightening the
screws may damage the mounting clips.
