DC supply and brake resistor cables

Frequency converters are equipped with terminals for the DC supply and an optional external brake
resistor. These terminals are marked with B–, B+/R+ and R–. The DC bus connection is made to terminals
B– and B+ and the brake resistor connection to R+ and R–. Note that the DC connection is optional for
drives greater than FR8.
