● Connect a terminating resistor between DA and DB.
● Connect the shielded wire of a CC-Link dedicated cable to SLD of each module and ground both ends via FG with a
ground resistance of 100 or less. SLD and FG are connected inside the module.
● Star topology cannot be used. However, T-branch connection can be used. ( Page 51, Section 6.4.3 (5))
(3) Terminal block for CC-Link
(a) Solderless terminal
For wiring, use the applicable solderless terminal and wire specified in the following table and attach them in an
applicable tightening torque. Use UL-listed solderless terminals. For processing, use a tool recommended by
manufacturers of solderless terminals.
Sleeved solderless terminals cannot be used.
Solderless terminal
Model
1.25 to -3
(b) Screw and tightening torque
Tighten the terminal block screws within the following specified torque.
Overtightening can damage the module case.
Terminal block screw (M3 screw)
Terminal block mounting screw (M3.5 screw)
● Prevent oil from adhering on the terminals and screws. Failure to do so may damage the screws.
● When inserting two solderless terminals, insert them back-to-back. Otherwise the screw cannot be tightened and it may
damage the screw.
● Tighten the terminal screws with an appropriate driver. Otherwise it may damage the screw.
(4) Wiring check
After wiring the master station, the bridge module, and the CC-Link remote station, check that the CC-Link
remote station is turned on/off by turning on/off the device of the master station.
