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.

Figure 1: Controller Mounting Positions

DIN Rail Mount Applications

Mounting the controller horizontal on 35 mm DIN rail is
the preferred mounting method.

To mount an FX-PCX 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 bottom mounting clips outward from the

controller to the extended position as shown in

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 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 controller off the DIN rail.

Wall Mount Applications

To mount an FX-PCX 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 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.
