3-6-2 Wiring the Connector
Strip the wires in the CC-Link cable, attach ferrules, and insert them into the connector.
To insert a ferrule, hold the orange tab in and insert the ferrule all the way to the back of the connector.
Then release the orange tab and pull lightly on the wire to confirm that the wire is securely connected.
The communications connector is labeled with the terminal names. Align the colors of the
communications wires with the terminal names on the connector to ensure that the wires are connected
correctly.

Precautions for Correct Use

tance.
Refer to documentation on the CC-Link Master Unit for information on connecting the terminating
resistance.
