All electrical equipment, including AC motor drives, will generate high-frequency/low-frequency noise 

and will interfere with peripheral equipment by radiation or conduction when in operation. By using 

an EMI filter with correct installation, much interference can be eliminated. It is recommended to use 

DELTA EMI filter to have the best interference elimination performance.
