V Bus-bar is Running voltage.

V Line is Incoming voltage.

Similarly, Figure 2.25-7 shows the VCT input voltages and phases from Bus-bar and Line.

In this case, configure the settings in accordance with Figure 2.25-7 and Table 2.25-8.

Output voltage at VT

Input voltage at VCHK

VCHK Setting

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.
