Brake unit selection depond on inverter power, user can consult with the braking unit merchants, Wecon does not sell braking units.

When you install braking unit,please do not move short splice beween P and +, connect braking unit between ''P  and -'' directly.  

The braking resistor should be connected to the braking unit.
