Observe the following 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 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 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 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.
