Mounting
Observe the following guidelines when mounting a PCA3613:
• 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 1).
• 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
• 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 PCA3613 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.
