① Wiring to the "brake resistor" connecon on the inverter or another component with brake chopper.
② Oponal: Wiring to a control contact, e. g. a digital input that is set to monitor the thermal contact. If the thermal
contact responds, the voltage supply of the inverter must be disconnected (e. g. switch o the control of the mains
contactor).
