Siemens SIMOTICS T-1FW6 - Defining the Direction of Rotation; Ambient Conditions for Fixed Operation

3.1.4 De󹪝ning 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.

3.1.5 Ambient conditions for 󹪝xed operation
Classify the environmental conditions for stationary use at weather-protected locations
according to the standard DIN IEC 60721‑3‑3. The environmental e󹪜ects and their limit values
are de󹪝ned 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.
Table 3-2 Ambient conditions are based on climate class 3K3
