13.1.6 Connection of the DC Bus Connections
General Information
Property damage in case of error caused by
too small line cross section!
Observe the current carrying capacity of the connection lines at the DC bus
connections of the components used; see chapter "DC Bus Connection (L+,
L-)" in the Project Planning Manual "Rexroth IndraDrive Supply Units and
Power Sections".
Install connection lines at the DC bus connections in such a way that they are
protected by the line protection at the mains connection of the supply unit or
by additional fuses before the connection line.
