1 ) One-pair Wiring
Note:
*1 Connect the terminal FG to the ground terminal of a programmable controller grounded
with a resistance of 100
Ω
or less (Class D grounding). If the programmable controller is
not equipped with a ground terminal, connect the terminal FG directly to a ground with the
resistance of 100
Ω
or less (Class D grounding).
2 ) Two-pair Wiring
Note:
*1 Connect the terminal FG to the ground terminal of a programmable controller grounded
with a resistance of 100
Ω
or less (Class D grounding). If the programmable controller is
not equipped with a ground terminal, connect the terminal FG directly to a ground with the
resistance of 100
Ω
or less (Class D grounding).
