1. 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.
