Environmental conditions
You can classify the environmental conditions for stationary use at weather-protected
locations according to the standard DIN IEC 60721-3-3. The environmental effects and their
limit values are defined in various classes in this standard.
With the exception of environmental influences "Low air temperature", "Condensation" and
"Low air pressure", you can assign SIMOTICS S-1FT7 servomotors to climate class 3K4.
The following temperature ranges apply for naturally-cooled and forced-ventilation motors.
