Danfoss NXIP54FR4 VACON NXP Air Cooled

GENERAL

Using these instructions, you can enhance the enclosure protection class of your IP21 class frequency converter to IP54. Such a higher protection level may be necessary when the frequency converter is used in such ambient conditions that might constitute a risk for the proper functioning of the converter (moist, dust). According to standard IEC 60529 (EN 60 529), the IP54 frequency converter enclosure provides protection against dust and water sprayed from all directions. Limited ingress of both is permitted.
