5.1 Precautions for Handling CC-Link Cables

This section explains how to handle dedicated CC-Link cables.
Do not perform any of the following, as each of them will damage
CC-Link cables:
• Compressing the cable with a sharp object
• Twisting the cable excessively
• Pulling the cable too hard (exceeding the allowable tension)
• Stepping on the cable
• Placing an object on the cable
• Scratching the cable sheath

5.2 Connecting CC-Link Cables

The following figure shows how safety remote I/O modules are
connected with dedicated CC-Link cables.

POINT
1)Connect the shielded wire of the CC-Link cable to SLD terminal of
each module, and ground both ends to the protective ground
connectors via FG terminals.
The SLD and FG terminals are connected inside the module.
2)Always connect terminal resistors to the modules located on both
ends of the data link network.
Connect a terminating resistor between DA and DB terminals.
