(4) The CC-Link-dedicated cable's shield wire (SLD) should be connected to the "FG" terminal of the SI unit.
For the EX140-SMJ1, the "SLD terminal" and "FG terminal" are common.
Therefore, connect 3 wires to the "FG Terminal" as shown in Fig. 4.
When connecting 3 wires to the "FG terminal", crimp 2 wires together into one crimped terminal as shown
in Fig. 5. Use another crimped terminal for other wires.
After crimping, connect wires so that the back of the two crimped terminals face each other.
