Figure 204: REFPDIF (87N) function inputs for autotransformer application
For normal transformers only one winding and the neutral point is available. This
means that only two inputs are used. Since all group connections are mandatory to be
connected, the third input needs to be connected to something, which is the GRP_OFF
signal in FXDSIGN function block.
