24 VDC external supply can be used as low-voltage supply to the control card and any option cards installed. This enables full operation of the LCP

however, there will be no tripping.
Use 24 VDC supply of type PELV to ensure correct galvanic isolation (type PELV) on the control terminals of the frequency converter.
