Figure 1: Controller mounting positions
DIN rail mount applications
About this task:
Mounting the controller horizontal on 35 mm DIN rail is the preferred mounting method.
To mount an FX-PCX controller on 35 mm DIN rail:
1. 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.
2. Pull the bottom mounting clip outward from the controller to the extended position as shown
in Figure 2.
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 clip inward (up) to secure the controller on the DIN rail.
To remove the controller from the DIN rail, pull the bottom mounting clip out to the extended posi-
tion and carefully lift the controller off the DIN rail.
Wall mount applications
About this task:
To mount an FX-PCX controller directly on a wall or other flat vertical surface:
1. Pull the bottom mounting clip outward and ensure it is locked in the extended position as
shown in Figure 2.
2. Position the controller in a proper mounting position shown in Figure 1 and mark the
mounting hole locations on the wall or surface using the dimensions shown in Figure 2. Or,
hold the controller up to the wall or surface in a proper mounting position and mark the hole
locations through the mounting clips.
