4.4.2.2 Dead Bus Closure CBA/CBB
General notes
NOTICE!
A dead bus closure can also be performed in the case of a mains failure. If the dead bus
closure should not be performed, the corresponding parameters must be switched "Oó°ˆ "
(parameter 8802, 8803 or 8804).
Case 1: Open Load Segment Closure
The load can be supplied either from the System A (CBA closed) or System B (CBB
closed). In general the CBA has a higher closing priority than CBB.
