3.4.10 Synchronism

The CFW-11M G2 RB and the CFW-11W G2 RB monitor the line voltage (R, S and T) at the converter input by means
of a synchronism board and two transformers. The signals obtained are used in the control of the regenerative
frequency converter.
The synchronism circuit wiring diagram can be seen in
be closed together with the main contactor K1. It is recommended to use a circuit breaker (QSINC) to protect the
synchronism transformers.
