Mounting
Observe the following guidelines when mounting a
field 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 correct mounting
position (Figure 2).
• Whenever possible in wall-mount applications,
mount the controller on a hard, even surface.
• 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 Technical specifications .
• Provide sufficient space around the controller for
cable and wire connections, 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 ductwork.
• 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.
