Input-Side Noise Filter
Drive outputs generate noise as a result of high-speed switching. This noise flows from inside the drive back to the power
supply, possibly affecting other equipment. Installing a noise filter to the input side of the drive can reduce the amount of
noise flowing back into the power supply. This also prevents noise from entering the drive from the power supply.
• Use a noise filter specifically designed for AC drives.
• Install the noise filter as close as possible to the drive.

This drive is tested according to European standards IEC61800-5-1 and complies with the EMC guidelines. Refer to
EMC Guidelines Compliance on page 255
for details about EMC filter selection and installation.

Output-Side Noise Filter
A noise filter on the output side of the drive reduces inductive noise and radiated noise.
illustrates an example
of output-side noise filter wiring.
NOTICE: Do not connect phase-advancing capacitors or LC/RC noise filters to the output circuits. Improper application of noise filters
could result in damage to the drive.
