3.3.3 Characteristics of the RFI Filter

CFW300 inverters, when installed with external filter, comply with the directive for electromagnetic
compatibility (2014/30/EU). The use of RFI filter kit indicated in the
equivalent, is required to reduce the disturbance conducted from the inverter to the power line
in the high frequency band (> 150 kHz) observing the maximum conducted emission levels of
electromagnetic compatibility standards, such as EN 61800-3.
