Connection

For B12C operation, the AC inputs of the two units are powered by the outputs of

a transformer with a Dy5d6 vector group. The master unit must be connected to the

secondary star output of the transformer. The slave unit must be connected to the

secondary delta output of the transformer.

Example vector group

For B18C operation, the AC inputs to the three units are powered by the outputs

of a transformer with a Dd0 d0+20° d0−20° vector group. The master unit must

be connected to the secondary delta 0° output of the transformer. The first slave

unit must be connected to the secondary delta 0+20° output of the transformer. The

second slave unit must be connected to the secondary delta 0−20° output of the

transformer.
