Auxiliary voltage transformers (T21, T101, T111). T21 is standard; T101 and T111 are added
whenever required by the options ordered.

12-pulse connection (A004)
The figure below illustrates the difference between 6-pulse and 12-pulse AC supply
connections. 6-pulse connection is standard. If the drive has an even number of supply
modules, you can order it as a 12-pulse version (A004).
12-pulse supply connection eliminates the fifth and seventh harmonics, which remarkably
reduces the harmonic distortion of the line current and the conducted emissions.
12-pulse connection requires a three-winding transformer, or two separate transformers.
There is a 30-degree phase shift between the two 6-pulse supply lines, which are connected
to different supply modules through electrically separate switching equipment.
