2.8.11.36 Direct power supply via the DC bus
This function is only available for inverters with nominal power ≥18.5 kW.
The direct power supply via the DC bus requires a protected direct current source with appropriate strength and
voltage as well as a suitably sized resistor and capacitor precharge contactor. Information on the data for these
components can be obtained from B&R.
The function "direct power supply via the DC bus" can be used to control the pre-charging contactor via a relay
or a logic input on the inverter.
