* 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 inverter will trip on over voltage.
*
Terminal at L2 will be non-functional for single-phase units.
