Communication Cable Topology
WARNING!
Fire Hazard. Tighten all terminal screws according to the specified tightening torque. Loose electrical connections could
result in death or serious injury by fire due to overheating electrical connections.
Tightening screws beyond the specified tightening torque may result in erroneous operation, damage to the terminal block, or cause a
fire.
Route the option wiring according to the following procedures.
1.
Connect the communication cables to the option modular connector CN1 as shown in
.
Figure 23
Figure 23 Connect Cable Wiring
2.
Take proper precautions to ensure that each cable is properly connected, and that wire insulation is not
accidentally pinched into the option modular connector CN1.
3.
After the option modular connector CN1 is fully attached to the CC-Link option, tighten the screws on the left and
right sides of the option modular connector CN1. (Tightening torque: 0.22 to 0.25 N
m (1.95 to 2.21 in
lb))

Termination Resistor Connection
When the CC-Link Option is the last station connected in a CC-Link network, the termination resistor needs to be
installed on that CC-Link Option. Cut the ring lugs from the termination resistor leads, and then loosen the DA and DB
terminals and insert the termination resistor between terminals DA and DB as shown.
Note:
Use the built-in termination resistor from the master if available, otherwise procure a standard-market resistor of 110
Ω
,
±
5% (1/
2 W).
