Defining the direction of rotation

Direction of rotation
If the built-in torque motor is connected with a phase sequence U-V-W, and is fed from a
three-phase system with a clockwise phase sequence, then the rotor rotates clockwise. You
can identify the direction of rotation by viewing the DE of the built-in torque motor. The cable
outlet of the built-in torque motor is on the opposite side – the NDE.

Environmental conditions for stationary use

You can classify the ambient conditions for stationary use at weatherprotected 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 "Low air temperature" and "Low air pressure" ambient parameters, you
can assign the motors to climatic class 3K3.
