supplies are used in the maximum configuration connectable
to the main unit or input/output extension units,
For the power (current) consumed by the input/output
extension units/blocks, refer to FX Series User's Manual -
3G
Hardware Edition. (The DC power type main unit does not
have a 24V DC service power supply.)
→ For the power consumed by the special extension blocks,
refer to the respective manual.

3.3 Grounding
Ground the PLC as stated below.
• Perform class D grounding. (Grounding resistance: 100 Ω or less)
• Ground the PLC independently if possible.
100 to 240V AC If it cannot be grounded independently, ground it jointly as shown
below.
