Wiring Precautions
Section 3-6
Inductive Loads
When an inductive load is connected to I/O, connect a surge suppressor or
diode in parallel with the load as shown below.
Note
Use surge suppressors and diodes with the following specifications.
External Wiring
Observe the following precautions for I/O wiring, power supply wiring, and
power line wiring.
• When multi-conductor signal cable is being used, do not combine I/O
wires and other control wires in the same cable.
• If wiring racks are parallel, allow at least 300 mm between the racks.
• If the I/O wiring and power cables must be placed in the same duct, they
must be shielded from each other using grounded steel sheet metal.
