Ferrite Collar

(Catalog Number 1747-FC)

The ferrite collar is intended for use with an RS-232 cable (catalog number 1747-CP3) connected to a 1747-L541, 1747-L542, 1747-L543 processor.

Install the collar for suppression of electromagnetic emissions and interference. The collar is required for compliance with the European EMC Directive.

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.

3. Check that the collar is fully latched.
