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 () 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:

13. Guarantee
All professionally installed, unaltered devices are covered by warranty during the statu-
tory guarantee period from the day of purchase by the end user. The guarantee is not ap-
plicable to damage incurred during transport or caused by short-circuit or overloading. In
the event of defects in workmanship or material, which are discovered within the guar-
antee period, the company will provide a replacement free of charge.
