2 RFI and motor filter not available for VLT 2040-2050, 3 x 208-240 V 3 VLT 2040-2050, 3 x 208-240 V are not available with built-in RFI filter. 4 VLT 2000 up to 415 V versions are available with built-in RFI filter. With the purpose of minimising the cable-conducted interference to the mains supply and the radiated interference from the frequency converter system, the motor cables should be kept as short as possible. According to experience, most installations represent only a slight risk of any interference from radiation. 90 MG.20.B6.02 – VLT is a registered Danfoss trademark
