Power Diagram A
Use this method if you are powering the display unit and or the dis-
play unit and a NMEA 2000 network. (Fuses may be different from
those shown.).
The network and any NMEA 2000 devices will not operate unless
the NMEA 2000 Power Cable is connected to power. (However,
never connect multiple power sources to a NMEA 2000 network.
If you have a network that is already powered, see diagram B on page
28.)
The method in diagram B is also used when your display unit is con-
nected to a NMEA 2000 network that is already connected to power.
(Never connect multiple power sources to a NMEA 2000 network.)
