1) Opens in case of thermal overload

2) Closes in case of thermal overload

• If the thermal circuit breaker trips, the signal contact is set (23-24 connection isopened, 11-12 connection is closed).

• The connection between inverter and braking resistor is disconnected.• This does not require a response by the PLC.• It is not required to disconnect the supply system connection with an external

switching device.• Set the control knob [4] of the thermal circuit breaker TCB to the tripping current IF

of the connected braking resistor. For doing so, set scaling to 40 °C.• After all cables are connected, the 3 upper screw holes must be covered with 3

touch guard caps. The touch guard caps are included in the delivery.
