Part 1 Installation
4. Noise Control Measures and Grounding
(1) Wiring and power supply
The PE terminal on the power-supply terminal block is used for protective grounding. Provide class D
grounding. The grounding wire should have a size of 1.0 mm
2
(AWG17) or larger and at least a size for AC
power wiring.
[1] Notes on wiring method
Do not twist the lines from the AC power supply and the 24-VDC external power supply. Wire the controller
cables separately from lines creating a strong electric field such as power circuit lines (by not bundling them
together or placing them in the same cable duct).
If you wish to extend the motor cable or encoder cable beyond the length of each supplied cable, please
contact IAI’s Technical Service Section or Sales Engineering Section.
(2) Grounding for noise elimination
Provide dedicated grounding.
