Din Rail Mount Applications; Wall Mount Applications - Johnson Controls MS-FEC1611-1U Installation Instructions Manual

• Mount the controller in an area free of corrosive vapors and observe the Ambient Conditions requirements in
Table 10.
• 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
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 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
positions shown in Figure
the hole locations through the mounting clips.
3. Drill holes in the wall or surface at the locations marked in
the mounting holes (if necessary).
