About this task
Mounting the field controller horizontal on 35 mm DIN rail is the preferred mounting method.
To mount a field controller on 35 mm DIN rail:
- 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 Figure 1.
- Pull the two bottom mounting clips outward from the controller to the extended position.
- Hang the controller on the DIN rail by the hooks at the top of the (DIN rail) channel on the back of the controller, and position the controller snugly against the DIN rail.
- Zip-tie the controller to the DIN rail (when shipping).
Push the bottom mounting clips inward (up) to secure the controller on the DIN rail.
Note: 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.Important: Do not overtighten the mounting screws. Overtightening the screws may damage the mounting clips.Figure 1. Back of Controller Showing Extended Mounting Clips, DIN Rail Channel, and Mounting Dimensions, mm (in.)
