DC Bus topology with busbar
This wiring does not require Y connectors. If a device fails due to a short-circuit, only its DC Bus
fuses (
# 39). are tripped and the rest of the network continues uninterrupted. The solid busbars
can conduct significantly larger currents, because the compensating current does not flow through
the connector as above. For this reason, almost as many drives as desired can be connected in
parallel in this form.
