Radio Frequency Interference (RFI) filters are typically required to meet the EN61800-3 standard. These filters are integrated in the Vacon NXS/P as standard.

The 208–240 V and 380–500 V ranges of the Vacon NXS fulfill all the requirements of the 1st and 2nd environments (H level: EN61800-3, category C2). No additional RFI filters or cabinets are required. The 525–690 V range of the Vacon NXS/P fulfills the requirements of the 2nd environment (L level: EN61800-3, catergory C3).

The units in the frame sizes of FR4, FR5 and FR6 (the voltage range from 380 to 500 V) are also available with extremely low-emission integrated EMC filters (C level: EN61800-3, category C1 or EN55011 class B). This is sometimes required in very sensitive locations such as hospitals.
