Chapter 2 – Twelve–Pulse Technology
DCS 600 Manual for 12 – Pulse Operation

12 – pulse con-
figuration with
only one main
contactor
Figure 2/17 shows the recommended connection of the necessary
signals. Each converter is connected in a similar way to a single
6 – pulse converter.
To perform an emergency operation with only one main contactor a
more detailed investigation is required as the handling of the main
contactor has to be switched over from the master to the emer-
gency converter (slave).
