4.5
Direction of rotation
If the mains with phase sequence L1, L2, L3 is connected to terminals U, V, W, the direction of rota-
tion of the motor will be clockwise as seen from the drive end.
If any two terminals are switched, the direction of rotation will be counter-clockwise.
For unidirectional motors, a plate will be provided indicating the direction of rotation and the phase
sequence to be applied (e.g., U, V, W).
This indication is present only when the motor, as a function of project characteristics, requires only
one direction of rotation (for example, anti run-back device installed).
Pay special attention when single direction status is imposed by machine or plant specifications.
4.6
FD brake connections
On standard single-pole motors, the rectifier is connected to the motor terminal board at the factory.
For switch-pole motors and where a separate brake power supply is required, connection to rectifier
must comply with brake voltage VB stated in motor name plate.
Because the load is of the inductive type, brake control and DC line interruption must use
contacts from the usage class AC-3 to IEC 60947-4-1.
