Power connection without line contactor

NOTICE

Operation without line contactor
If the required measures are not taken, operation of an inverter with connected braking resistor without line contactor may result in severe damage to property.
  • Required measures as well as the inverters that can be operated without a line contactor can be found in the chapter Using the line contactor.

INFORMATION

Line connection without line contactor
In the event of a line connection without line contactor, the temperature evaluation of the braking resistor must be ensured via a digital input on the inverter.
  • Parameterize the connected digital input to monitor the braking resistor temperature evaluation.

The following figure shows an example of the wiring of the power connections without line contactor, with line choke, line filter and output choke and/or output filter:
