The technical specifications stipulate the following that have to be taken into account with
respect to the motor connection:
● Direction of rotation.
● The number and arrangement of the terminal boxes.
● The circuit and connection of the machine winding.
6.2.1 Terminal designations
With the terminal designations according to DIN VDE 0530 Part 8 or EN / IEC 60034-8 for
three-phase machines, the following principle definitions apply:
Table 6- 1 Terminal designations (with the 1U1-1 as an example)
1 U 1 - 1 Designation
x Index showing the pole assignment for pole-changing machines (where appli-
cable, a lower number indicates a lower speed) or, in special cases, for a
subdivided winding.
x Phase designation (U, V, W)
x Index showing the start (1) / end (2) or tapping point of the winding (if there is
more than one connection per winding)
x Additional index for cases in which it is obligatory to connect parallel power
feed cables to several terminals with otherwise identical designations
6.2.2 Direction of rotation
The standard motors are suitable for clockwise and counter-clockwise rotation.
For defined directions of rotation (direction of rotation arrow), appropriately connect the line
power cables.
● If you connect the line cables with phase sequence L1, L2, L3 at U, V, W or according to
NEMA at T

, then the machine rotates in the clockwise direction.
● If you interchange two connections, e.g. L1, L2, L3 at V, U, W or according to NEMA at
