7.4.1
Panel inside wiring
In wiring, the power line connected to the power or servo amplifier and the communication cable such as bus connection
cable or network cable must not be mixed.
Mixing the power line and communication cable may cause malfunction due to noise.
When using an equipment that may occur surge noise, such as molded case circuit breaker (MCCB), electromagnetic
contactor (MC), relay (RA), solenoid valve, or induction motor, using a surge suppressor is effective.
For surge suppressor, refer to the following.
7.5 Attaching Surge Suppressor for Control Equipment
7.4.2
Panel outside wiring
When leading the power line and communication cable outside the panel, open cable holes at two separate places to
lead the cables separately out.
If cables are led out through the same cable hole for wiring reasons, the cables are more easily influenced by noise.
Install the power line and communication cable as apart from each other as possible in the duct.
If the cables are installed closely with each other for wiring reasons, using a separator (made of metal) can make the
cables less influenced by noise.
