EMC / noise level of inverter
Electromagnetic compatibility (EMC) refers to that one electrical equipment functions in a
given electromagnetic environment without any trouble or error, and impose no unacceptable
effect upon the environment. Therefore, EMC represents the quality characters of an electrical
equipment.
The inherent noise-immune character: immunity to internal electrical noise.
External noise immunity: immunity to electromagnetic noise of external system
Noise emission level: influence of electromagnetic emission upon environment.
Electromagnetic radiation from inverter may be harmful to health!
Please do not continue to stay around the inverter in less than 20 cm when
inverter is working.
