The signals from other bays connected to the module A1A2_DC are described below.
11.5.6.2
Signals in single breaker arrangement
If the busbar is divided by bus-section disconnectors, the condition
no other disconnector
connected to the bus-section
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
signals from busbar B are used.
