controller
The power terminal block does not have a protective grounding terminal, but the user must separately
provide a noise elimination measure and grounding.
(2) Grounding for noise elimination
Regardless of whether the power supply is 100/200 VAC or 24 VDC, the controller must always be
grounded to eliminate noise.
[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.
