  • Page 38: Noise Malfunction And Electromagnetic Interference

    8-5. Noise Malfunction and Electromagnetic Interference An inverter A/C operates using pulse signal control and high frequencies. Therefore, it is susceptible to the effects of external noise, and is likely to cause electromagnetic interference with nearby wireless devices. A noise filter is installed for ordinary use, preventing these problems. However, depending on the installation conditions, these effects may still occur.
