(Refer to Chapter 4

On Unidrive SP size 2 and 3, the high current DC connections must
always be used when using a braking resistor, supplying the drive from
DC (low voltage 48V or high voltage) or using the drive in a parallel DC
bus system. The low current DC connection is used only to connect the
internal EMC filter.
See Figure 6-9 for further information on ground connections.
