Table 4.29 Terminals for 24 V DC External 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 line power. Note that a
warning of low voltage is given when 24 V DC has been
connected; however, there is no tripping.
WARNING
To ensure correct galvanic isolation (type PELV) on the
control terminals of the adjustable frequency drive, use
24 V DC supply of type PELV.
4.1.18 Access to Control Terminals
All terminals to the control cables are located beneath the
LCP. They are accessed by opening the door of the IP21/
IP54 unit, or by removing the covers of the IP00 unit.
