24 V external DC supply
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
(including parameter setting) without connection to line power. Please note that a warning of low voltage will be given when 24 V DC has been connected;
however, there will be no tripping.
Use 24 V DC supply of type PELV to ensure correct galvanic isolation (type PELV) on the control terminals of the adjustable frequency
drive.
