Connecting the braking resistor

The braking resistor is connected at terminals DCP/R1 and R2.
FSA ... FSF: The braking resistor can be connected directly to the Power Module.
FSGX:
On FSA to access the R1/R2- terminals the cutout cover must be removed using a small pair
of cutters, ensuring that no plastics from the cutout fall into the inverter housing. On FSB and
FSC the R1/R2- terminals are located on the underside at the bottom of the unit (see
Figure). The terminal connection consists of up to three spades.
