The ferrite collar is intended for use with an RS-232 cable (catalog
number 1747-CP3) connected to a 1747-L541, 1747-L542,

To be effective, the ferrite collar must be placed on the cable where
the cable exits the module (see figure).
1. Fold the collar so that it encircles the cable.
2. Press the plastic housing until the collar snaps together.
