6.6 Connecting the motor in the terminal box
Please note that the motor degree of protection is only obtained after correctly connecting
up and tightening the cable glands and blanking plugs. Seal the thread of the cable glands
and sealing plugs with a sealing compound or O-ring when connecting.
6.6.3
Terminal marking
For terminal designations, the following principle definitions apply to three-phase motors:

Direction of rotation
The motors are suitable for clockwise and counter-clockwise rotation.
When the line feeder cables are connected in the phase sequence L1, L2, L3 to U, V, W the
motor rotates clockwise when looking at the drive end of the shaft extension (DE). If 2 of
the connections are interchanged, the resulting direction of rotation is counter-clockwise,
e.g. L1, L2, L3 at V, U, W. For the converter world motor, the direction of rotation is specified
by the converter and the gearbox code.
In the case of geared motors intended for only 1 direction of rotation, e.g. with backstop, the
specified direction of rotation is marked by a direction arrow on the geared motor.
