Important: Only qualified personnel should install or service Verasys products. These instructions are a guide for such personnel. Mount the Verasys controllers on a wall or DIN rail inside an enclosure (rated at least IP20). Carefully follow all instructions in this document and all instructions for the controller.
Follow these guidelines when mounting a field controller:
- Ensure that 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, see Figure 1.
- 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 condition requirements in Table 1.
- Provide sufficient space around the controller for cable and wire connections, for easy cover removal, and good ventilation through the controller. Provide a minimum of 50 mm [2 in.] 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.
Follow 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.
- Use a zip tie to secure the controller when shipping.
