Zero-Phase Reactor - YASKAWA CIMR-JC4A0002BAA Quick Start Manual

7.4 Installing Peripheral Devices
Reducing Radiated/Radio Frequency Noise
The drive, input lines, and output lines generate radio frequency noise. Use noise filters on
input and output sides and install the drive in a metal enclosure panel to reduce radio frequency
noise.
Note: The cable running between the drive and motor should be as short as possible.
