4.6.3 Rotation direction of the drive motor
(See the arrow on the motor housing)
DANGER!
Mains voltage!
Changes to the rotation direction may only be made by
a qualified technician.
The direction of rotation of the three-phase AC motor must anticlockwise
as seen through the ventilation grid from the frontal perspective.
The single-phase motor is set at the factory to an anticlockwise direction
of rotation; see:
DIN VDE 0530 Part 8 "Terminal Markings and Direction of Rotation"
DIN VDE 0530 Part 7 / EN 60 934-7 "Abbreviations for Models"
The direction of rotation is changed by swapping two supply lines "L1, L2,
L3" (or the power supply line "U1, U2, U3" in the socket).
