11. Putting into Service

The circuit boards have to be operated with 24 VDC at terminals POW (24 VDC) and
BUS- (0 V). In order to avoid differences in potential, the common (O V) wire of the
voltage supply must be directly connected together with the Dupline signal con-
ductor (Dupline-) to the „BUS-" terminal. At no other point is a connection between
the two leads permissible. The internal 24 VDC voltage at the terminal DC+ of the
DNP 8A can be used as supply voltage for the loads at terminals O1..O8.
The Dupline signal must be routed to terminals DUP (Dupline+) and BUS- (Dupline-). At
no point within the system may the Dupline signal have a connection to earth potential.
The following table illustrates the connection configuration:
