When the external brake
resistor is needed,
disconnect the short wires
between B1 and B2 [note
2] and crossover the
external brake resistor to
terminals P and B1. Leave
B2 unconnected.

When the external brake
resistor is needed, it must
disconnect the internal
brake resistor wire between
terminals P and B firstly,
connect those two wires to
NC at the same time, and
then crossover the external
brake resistor to terminals
P and B.
