(1) Noise Elimination Grounding
1. Directly screw the main body to the metal box.
[3] Precautions regarding wiring method
Use a twisted cable for connection to the 24-VDC external power supply.
Separate the controller cables from high-power lines such as a cable connecting to a power circuit. (Do not
bundle together the controller cables with high-power lines or place them in the same cable duct.)
When extending the supplied motor cable or encoder cable, consult IAI’s Technical Support or Sales
Engineering Section.
Use as thick a cable as
practically possible and wire
it over the shortest possible
distance.
