ATTENTION
During installation, attention must be paid to proper sealing (do not forget the rubber
seal!), to prevent the entry of moisture.
With IP66 versions, care must also be taken that the cables and cable glands at least
comply with protection class IP66, so that compliance with protection class IP66 is
ensured on the frequency inverter.
