If the busbar is divided by bus-section disconnectors, the condition for the busbar dis-
connector bay QR RWKHU GLVFRQQHFWRU FRQQHFWHG WR WKH EXV VHFWLRQ must be made by a
project-specific logic.
The same type of module (A1A2_DC) is used for different busbars, that is, for both bus-
section disconnector A1A2_DC and B1B2_DC. But for B1B2_DC, corresponding sig-
nals from busbar B are used.
