Connection diagram
The electric machines are intended to be powered and controlled by three-phase alternating current,
supplied by an inverter or inverters. The electric machine is not suitable for direct online use.
The amount of inverters depends on the electric machine and converter current ratings.
For an electric machine with option DUAL (two connection boxes each containing one three-phase
system), the electrical connection principles from the inverters are shown in the Figure below.
