35, 36 24 V external DC supply
External 24 V DC supply can be used as low-voltage
supply to the control card and any option cards
installed. This enables full operation of the LCP (incl.
parameter setting) without connection to mains.
Please note that a warning of low voltage will be
given when 24 V DC has been connected; however,
there will be no tripping. If 24 V external DC supply
is connected or switched on at the same time as
the mains supply, a time of min. 200 msec. must
be set in parameter 120 Start delay.
A pre-fuse of min. 6 Amp, slow-blow, can be
fitted to protect the external 24 V DC supply.
The power consumption is 15-50 W, depending
on the load on the control card.
NB!:
Use 24 V DC supply of type PELV to ensure
correct galvanic isolation (type PELV) on the
control terminals of the frequency converter.
