ATTENTION!
Protect 24 V section externally!
This 24 V section must be protected externally with a fuse. The power supply unit must
be capable of supplying 4 times the rated current, so that in case of a fault, blowing of
the fuse is assured.

Via potential shunting
The voltages forwarded from the bus
terminal to the potential shunters (main and
segment voltage) follow the applied supply
voltages without delay.
