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.

Ambient conditions for fixed operation

Classify the environmental conditions for stationary use at weather-protected 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 environmental parameters "Low air temperature" and "Low air
pressure", the motors satisfy climate class 3K3.
