11.7 Details on insulation, protection class, degree of protection and rated voltage

Water directed as a jet against the housing from any direction must have no harmful
effects.
Water must not enter in a quantity to cause harmful effects when the enclosure is
temporarily immersed in water under standardized pressure condition and time
conditions.
