Grounding

Ground the cables as follows
• The grounding resistance should be 100Ω or less.
• Grounding should perform independent grounding as far as possible.
Independent grounding should be performed for best results.
When independent grounding is not performed, perform "shared grounding" as shown in the following
figure.
For details, refer to the following respective PLC manual.
• The grounding wire size should be AWG22-20 (0.3 to 0.5 mm
• The grounding point should be close to the PLC, and all grounding wires should be as short as possible.
