III.Precautions for use
Grounding treatment:
The GR terminal is the earth grounding terminal.It should be grounded using a wire with a cross-sectional area ofmore than 2mm²and the third grounding method(grounding resistance less than 100Ω).
If malfunction occurs due to loud noise or to prevent electric shock,LG(neutral terminal of noise filter)can be short-circuited with GR and the third grounding method can be used.
Drive circuit:
When the PLC output cannot directly drive the load,a drive circuit must be used externally,such as a solid-state relay or thyristor circuit drive.
At the same time,a protection circuit and a surge absorption circuit should be used to ensure the stability and safety of the circuit.
