My fan’s VFD generates radio frequency (RF) noise.

VFDs generate RF noise in many ways, but this can be prevented using proper wiring practices.

  • Do not run your fan and sensitive equipment on the same power line.
  • Ensure proper grounding at the motor, at the VFD, and from the VFD to the utility.

If noise is still present, contact Customer Service.
