Communication Cable Wiring
■ Procedure
Follow the instructions below to connect the communications cable to the terminal block.
NOTICE: Tighten all terminal screws according to the specified tightening torque. Failure to comply can cause a short-circuit or drive malfunction.
1.
Connect the communications cable to the terminal block as shown in the diagram below.
Note: Communication lines should be separated from main circuit wiring and other electrical lines. (Tightening torque: 0.22 to 0.25 (Nxm))

Figure 6 Comm Cable Wiring
2.
Take particular precautions to ensure that each cable is properly connected, and that wire covering has not been accidentally inserted into
the terminals.
3.
After the terminal block is fully attached to the CC-Link option, tighten the screws on the left and right sides of the terminal block. (Tightening
torque: 0.22 to 0.25 (Nxm))
