Environmental conditions
You can classify the ambient conditions for stationary use at weather-protected locations
according to 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 "Condensation" and "Low air pressure" environmental parameters, you
can assign SIMOTICS T-1FW3 complete torque motors to climatic class 3K4. Condensation
and expansion of the temperature range are not permissible.
