* Braking units are required for applications where a load with high inertia
needs to be stopped rapidly. Use a power-matched braking unit and resistor to
dissipate the energy generated by the load while stopping. Otherwise VSD will
trip on over voltage.
* Terminal at L2 will be non-functional for single-phase units.
