The table below lists the performance of 400V-class inverter models with the optional external
braking units. In some cases, the resistor selection specifies multiple resistors in a parallel,
series, or combination parallel/series configuration. The example diagram shows a combination
parallel / series configuration. Please refer to the braking unit manual for detailed wiring
diagrams.
