About this task

Mounting the FX-PCX expansion module horizontally on 35 mm DIN rail is the preferred method.

To mount an expansion module on a 35 mm DIN rail, complete the following steps:


  1. Securely mount a 20 cm (8 in.) or longer section of 35 mm DIN rail, horizontally and centered in the desired space, so that the expansion module mounts in the position shown in Figure 1.
  2. Pull the two bottom mounting clips outward from the expansion module to the extended position (Figure 1).
  3. Hang the expansion module on the DIN rail by the hooks at the top of the DIN rail channel on the back of the expansion module (Figure 1), and position the expansion module snugly against the DIN rail.
  4. Push the bottom mounting clips inward (up) to secure the expansion module on the DIN rail.
    To remove the expansion module from the DIN rail, pull the bottom mounting clips out to the extended position and carefully lift the expansion module off the DIN rail.
