6.2.2 I/O Device Wiring
1) The spec. of I/O wiring cable is 0.18~2 mm
2
and it is recommended to use the cable spec. (0.5mm
2
) conveniently.
2) Input cable and output cable should be separated for wiring.
3) I/O signal cable should be separated at least 80mm from main circuit cable of high voltage, high current when wiring.
4) In case it is not available to separate the main circuit cable and the power cable, please use the shielded cable and earth
the PLC.
5) In case of pipe wiring, make sure of the pipe and then ground it.
6) DC24V output cable should be separated from AC110V cable and AC220V cable.
7) In case of wiring the long distance more than 200m, the error occurs according to the leakage current caused by the
interline capacity.
6.2.3 Grounding Wiring
1) As this PLC carries out sufficient noise policy, it is available to use without grounding except the case where there is much
noise. But, when grounding, please refer to the following notices.
2) When grounding, please use the exclusive grounding if possible.
For he grounding construction, please use the 3 rd class grounding (grounding resistance less than 80

).
3) If not available to use the exclusive grounding, please use the common grounding as shown on the figure (B).
(A) exclusive grounding: Excellent (B) common grounding: Good (C) common grounding : Bad
