DIN rail mount applications
Mounting the PCA3613 controller horizontally on 35 mm DIN rail is the preferred mounting
method.
To mount a controller on 35 mm DIN rail, complete the following steps:
1. Securely mount a 23 cm (9.125 in.) or longer section of 35 mm DIN rail, horizontally and
centered in the desired space, so that the controller mounts in the position shown in Figure 1.
2. Pull the two bottom mounting clips outward from the controller to the extended position
3. Hang the controller on the DIN rail by the hooks at the top of the (DIN rail) channel on the back
of the controller (Figure 2), and position the controller snugly against the DIN rail.
4. Push the bottom mounting clips inward (up) to secure the controller on the DIN rail.
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.
Wall mount applications
To mount a PCA3613 directly on a wall or other flat vertical surface, complete the following steps:
1. Pull the two bottom mounting clips outward and ensure they are locked in the extended
position as shown in Figure 2.
2. Mark the mounting hole locations on the wall using the dimensions in Figure 2 and one of the
mount positions shown in Figure 1. Or hold the controller up to the wall or surface in a proper
mount position and mark the hole locations through the mounting clips.
3. Drill holes in the wall or surface at the marked locations, and insert appropriate wall anchors in
the holes (if necessary).
4. Hold the controller in place, and insert the screws through the mounting clips and into the
holes (or anchors). Carefully tighten all of the screws.
Important:
Do not overtighten the mounting screws. Overtightening the screws may
damage the mounting clips.
