9.2 Wiring
The followings explain the wiring instructions for use of the system.
9.2.1 Power Supply Wiring
(1) To protect the PLC from noise, twist the power line as densely as possible, and keep the shortest distance.
(2) Connect a power supply that has less noise (if there are lots of noise, connect noise filter).
(3)
When wiring, separate the PLC power supply from those for I/O and power device as shown below.
(4)
To minimize voltage drop, use the thickest (max. 2 ㎟) wires possible
(5) Do not bundle the 24VDC cable with main-circuit (high voltage, large current) wires or the I/O signal wires.
If possible, provide more than 80 ㎜ distance between the cables and wires.
