For example, if you have to extend the power cable to the battery or
power buss, attach one end of the fuse holder directly to the battery or
power buss. This will protect both the unit and the power cable in the
event of a short. It uses a 3-amp fuse.
Power connections for the units in this series.
NOTE:
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 –.
WARNING:
This product must be independently fused with the en-
closed 3-amp fuse (or equivalent), even if you connect to
a fused accessory or power buss.
If a malfunction happens inside the unit, extensive dam-
age 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.
