Ambient conditions

You can classify the ambient conditions according to the standard DIN EN 60721‑3‑3: 1995-09
for stationary, weather-protected use.
With the exception of environmental influences "Low air temperature", "Low air pressure", and
"Condensation", the motor complies with climate class 3K4.
