The connection to the circuit breakers is not dependent on direc-
tion and polarity; the circuit diagrams can be adapted
accordingly.
If the parallel or series connections are made directly to the
connecting bars, for thermal reasons the continuous load on the
circuit breakers must only be 80 % of the permissible operational
