Environmental conditions

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