3.2.7 Synchronism
The CFW-11 RB monitors the line voltage (A, B and C) at the converter input with two transformers and asynchronism
board. These signals are used for the regenerative converter control. In order to execute this monitoring, it is
necessary to connect the power line to points 1, 2 and 3 of the synchronism terminal, as shown in
on page
3-29.
Frames F and G have fuses inside the product to protect the synchronism circuit. Frame E does not have such fuses,
which can be added outside the product. Example: Fuses manufacturer Ferraz Shawmut model FR14GG69V4.
