NMEA 0183
Data Cable
Power connections for the units in this series.
NOTES:
If you're powering a NMEA 2000 buss, you will attach both the
NMEA 2000 Power cable and the unit's Power Supply cable to the
boat's battery. To attach the NMEA 2000 Power cable, connect the
red wire to battery's + and black and shield wires to battery's –.
If you are not powering a NMEA 2000 buss, we recommend capping
all unused, exposed wire ends with wire nuts or electrical tape and
tucking the excess cable out of the way. This will prevent an
electrical short.
WARNING:
This product must be independently fused with the
enclosed 3-amp fuse (or equivalent), even if you connect
to a fused accessory or power buss.
If a malfunction happens inside the unit, extensive
damage can occur if the enclosed fuse is not used. As
with all electrical devices, this unit could be damaged to
a point that it is unrepairable and could even cause
harm to the user when not properly fused.
CAUTION:
Do not use this product without a 3-amp fuse wired into the power
cable! Failure to use a 3-amp fuse will void your warranty.
