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.
For an electric machine with option DUAL (two three-phase systems), the electrical connection
principles from the inverters are shown in Figure below.
For an electric machine with connection option other than SINGLE, the electrical connection
principles from the inverters are shown in the Figure below. See also Wiring Diagram. The amount
of inverters depends upon the motor and converter current ratings.
Figure 16. Connection diagram for DUAL option
For an electric machine with option QUAD (four galvanically isolated three-phase systems), the
electrical connection principles from the inverters are shown in Figure Connection diagram for
QUAD option.
