Grounding; Power Supply Specifications And Wiring Diagram; Input Specifications And Wiring Diagram - Mitsubishi Electric FX3S Quick Start Manual

4.2 GROUNDING

Ground the PLC as stated below.
• Perform class D grounding. (Grounding resistance: 100Ω or less)
• Ground the PLC independently if possible.
If it cannot be grounded independently, ground it jointly as shown
below.

equipment equipment
Independent grounding Shared grounding
(Best condition) (Good condition)
• Use ground wires thicker than AWG14 (2 mm²).
• Position the grounding point as close to the PLC as possible to
decrease the length of the ground wire.
