Table 3.52 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

setting) without connection to mains. Note that a warning
of low voltage is given when 24 V DC has been connected;
however, there is no tripping.
WARNING
Use 24 V DC supply of type PELV to ensure correct
galvanic isolation (type PELV) on the control terminals of
the frequency converter.
