Materials and Special Tools Needed

• three fasteners appropriate for the mounting surface
(M4 screws or #8 screws)
• one 20 cm (8 in.) or longer piece of 35 mm DIN rail
and appropriate hardware for DIN rail mount (only)
• small straight-blade screwdriver for securing wires in
the terminal blocks
Mounting
Observe these guidelines when mounting a controller:
• Ensure the mounting surface can support the
controller, DIN rail, and any user-supplied enclosure.
• Mount the controller horizontally on 35 mm DIN rail
whenever possible.
• Mount the controller in the proper mounting position
(Figure 1).
• Mount the controller on a hard, even surface
whenever possible in wall-mount applications.
• Use shims or washers to mount the controller securely
and evenly on the mounting surface.
• Mount the controller in an area free of corrosive
vapors and observe the Ambient Conditions
requirements in Table
• 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 an
IOM47 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 an IOM47 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. 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 (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 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
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).
