Table 4.21 Terminals for 24 V External DC Supply
24 V DC 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 the mains. A warning of low
voltage is given when 24 V DC has been connected;
however, there is no tripping.
NOTICE
Use 24 V DC PELV supply to ensure correct galvanic
isolation (type PELV) on the control terminals of the
frequency converter.
