Wiring the Module

Installing the Ferrite Collar

For immunity to electrical noise with this CE-marked module, insert

ferrite collar (Fair-Rite Inc. part number 0443164151) around the input

cables immediately beneath the module in the I/O chassis. 

Do this as follows:

1. Bundle the cables at the module end.

2. Fold the collar so that it encircles the cables.

3. Press the plastic housing until the collar snaps together.

4. Check that the collar is fully latched.

5. If the collar slides on the cables, use a cable tie to secure it.
