The evaluation in case of IP65 shows that there are no restrictions on the absolute
limit values and that the full performance potential of the stainless steel explosion pro-
tection enclosure can be used.
The evaluation in case of IP67 shows that there are limitations in ambient tempera-
tures and power classes.
