Signals in double-breaker arrangement

If the busbar is divided by bus-section disconnectors, the condition for the busbar disconnector
no other disconnector connected to the bus-section must be made by a project-specific logic.
bay
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 signals from busbar B are
used.
