    [3] Inverter

    [4] Control knob

    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 is opened, 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.
