*1. To use the braking resistor (3G3AX-RAB/RBB/RBC) for the 400-V class regenerative braking unit, be sure to remove the
built-in resistor and connect two resistors of the same model in series. Using a 400-V class regenerative braking unit with
only a single braking resistor connected may cause damage to the braking resistor.
