If the I/O connections, 24 VDC, Modbus, analog outputs, or analog inputs (4-20 mA) are
not connected by a shielded connection, conduit or multi-conductor braded shield cable,
then these wires must be clipped in a ferrite to meet the EMC specifications. Figure AH-
9 shows and example of this type of wiring.
