3. Installation and wiring
3.2. Wiring
Separate the 24V DC output cable from 110V AC cable and 220V AC cable.
In the cases where wiring is longer than 200m, error occurs depends upon the
leakage current that is caused by interline capacity.
Grounding Wiring
If there is more noise, you have to use PLC with grounding. During grounding, refer to
the following notices.
1.
During grounding, use the exclusive grounding if possible. For the grounding
construction, use the 3rd class grounding (grounding resistance less than 80Ω).
If the exclusive grounding is not possible to use, you can use the common
grounding as shown on the figure (B).
(A): exclusive grounding: Excellent
(B): common grounding: Good
(C): common grounding: Bad
For grounding, use the electric wire that is more than 2mm² of thickness. Place
the grounding point near this PLC if possible and shorten the length of the grounding
cable.
