CABLING AND CONNECTIONS vacon • 4566.1.1.2 DC supply and brake resistor cablesVacon AC drives 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– andB+ and the brake resistor connection to R+ and R–. Note that the DC connection is optional for drivesgreater than FR8.6.1.1.3 Control cableFor information on control cables see Chapter 6.2.1.1 and Table 6-1.6.1.1.4 Cable and fuse sizes, NX_2 and NX_5, FR4 to FR9The table below shows typical cable sizes and types that can be used with the converter.
