Powering a NMEA 2000 Buss

(NMEA 2000 Power cable)

A NMEA 2000 buss must be connected to a power source to operate. If you have a pre-existing NMEA 2000 installation, it may already be connected to another power source. If your NMEA 2000 buss is already powered, you can ignore the NMEA 2000 Power cable. Never attach two power sources to a single NMEA 2000 buss.

If you do need to power your NMEA 2000 buss, attach the NMEA 2000 Power cable to your boat's battery just as indicated in the following segment for connecting your unit's Power Supply cable. The NMEA 2000 Power cable's red wire should be attached (with provided 3-amp fuse) to the boat battery's positive terminal, and the NMEA 2000 Power cable's black and shield wires should both be attached to the battery's negative terminal.

NOTE:

If the NMEA 2000 buss draws power directly from the boat's battery, the LGC-2000 will remain on (drawing power) all the time. The LGC- 2000's current draw is very small and shouldn't decrease the boat's storage battery life, but if this small draw is a concern, you can install a switch between the NMEA 2000 buss and the battery.

Powering Your Unit

(Power Supply cable – red and black wires)

The unit works from a 12-volt battery system. For the best results, attach the power cable directly to the battery. You can attach the power cable to an accessory or power buss, however you may have problems with electrical interference. Therefore, it's safer to go ahead and attach the power cable directly to the battery.

CAUTION:

When using the unit in a saltwater environment, we strongly recommend that you shut off the power supply to the power cable when the unit is not in use. When the unit is turned off but still connected to a power supply, electrolysis can occur in the power cable plug. This may result in corrosion of the plug body along with the electrical contacts in the cable and the unit's power socket.

In saltwater environments we recommend you connect the power cable to the auxiliary power switch included in most boat designs. If that results in electrical interference, or if such a switch is not available, we recommend connecting direct to the battery and installing an inline switch. This will let you shut off power to the
