You can assign the SIMOTICS M‑1PH8 main motors to climate class 3K4 with the exception of
the environmental parameter "condensation". Condensation is not permissible.
The higher the last number in the climate class 3K☐, the greater the requirements of the
motor.

In Central Europe, the midday sun stands at 60 ° to 65 ° and, in ideal weather conditions, shines with an irradiance of approx.
700 watts/square meter. In winter, the angles are only 13 ° to 18 ° and, even at noon, the irradiance is only approx. 247 watts/
square meter.
You will nd additional data on the ambient conditions, such as ambient temperatures
or conditions for transport and storage of the motors, in the relevant chapters of this
documentation.
3.3 Derating factors
Derating for ambient/coolant temperature
Operation: T = -15°C bis +40°C (without restriction)
Under conditions other than those specied above (ambient temperature > 40 °C or installation
altitude > 1000 m above sea level), the permissible torque/power reduction must be considered
(see Chapter "Ambient/coolant temperature (Page67)")
