2.3.4 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.

Conditions in mines are not considered.
Climate-controlled locations with a tolerance of ±2 °C, referred to defined limit values.
A cooling system based on natural convection can be disturbed by unforeseen air movements.
5)
The limit value of 89 KPa covers altitudes up to1000 m.

Additional data on the ambient conditions
You will find 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.
