is Incoming voltage.
Similarly, Figure 2.35-7 shows the VCT input voltages and phases from Bus-bar and Line.
In this case, configure the settings in accordance with Figure 2.35-7 and Table 2.35-8.

[SYN-VBus] = V-L23
[SYN-VLine]= V3

Note: V3 is set for the scheme switch [SYN-VLine]. This is because the resultant phase
of V-L2, V-L3 and V3 is same.
