VLT HVAC Drive Operating Instructions
If a short circuit in the brake IGBT occurs, prevent power
dissipation in the brake resistor by using a mains switch
or contactor to disconnect the mains for the frequency
converter. Only the frequency converter shall control
the contactor.
Place the brake resistor in an environment free of fire
risk and ensure that no external objects can fall into the
brake resistor through ventilation slots.
Do not cover ventilation slots and grids.
