Where do I connect my NMEA 2000 to power?

NMEA 2000 networks must be connected to a 12 Vdc power source using a dedicated NMEA 2000 power cord.

 

 

When connecting an NMEA 2000 network to a power source, the following precautions must be observed:

 

 

The dedicated NMEA 2000 power cord must be connected to 12 Vdc. Connecting to 24 Vdc or any power source higher than 12 Vdc may damage NMEA 2000 network components or devices.

 

 

A dedicated NMEA 2000 power cord should be connected to the power source via the boat's auxiliary power switch. If there is no auxiliary power switch, or if connecting an auxiliary power switch would cause electrical interference, the power cord must be connected to the power source through a series switch.

 

 

The dedicated NMEA 2000 power cord must be connected to the top of the T-connector, not the side.

 

 

The power cord can be connected to the top of the T-connector at either end or in the middle of the NMEA 2000 network backbone, depending on the length of the backbone and the power needs of the devices on the network (power distribution and balancing).

 

 

Some NMEA 2000 devices provide power for NMEA 2000 networks, but this may not be appropriate for every NMEA 2000 design. To avoid having two power supplies connected to the network, you can install these devices using power isolators
