DC power and braking unit connect terminals, applied in large load inertia or short
deceleration time and inverter tender to trip. (matching with Braking Unit and brake
resistor to brake)

Grounding terminal (2 points)
* Brake units are required for applications where a load with high inertia needs to be stopped rapidly.
Use a correctly rated braking unit and resistor to dissipate the energy generated
by the load while stopping. Otherwise inverter will trip on overvoltage.
