Wiring
Observe the following points when wiring power supply and signal cables.
• When routing signal cables with differing characteristics through the same duct, always keep
them separated.
• As much as possible, avoid routing multiple power supply lines through the same duct.
If it cannot be avoided, then construct a partition between them in the duct and ground the parti-
tion.
• To avoid overheating the conduits when using conduits for wiring, do not place wires for a single
circuit in separate conduits.
• Power cables and signal cables adversely affect each other. Do not wire them in parallel.
• Noise induction may occur if the Controller is installed in a panel that includes high-voltage
devices. Wire and install them as far apart as possible. (Refer to
