9.5 Magnetic Ring and Buckle
The magnetic ring can be used on the input or output side of the AC drive. Install it as
close to the AC drive as possible. When installed on the input side, the magnetic ring
can suppress the noise in the input power supply system of the drive. When installed
on the output side, the magnetic ring can suppress interference generated by the AC
drive to external devices and reduce the bearing current.
