Environmental conditions

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