Power and optional speaker connections for the GlobalMap 5500C and

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. You must also attach both the power cables to the
battery when you are only connecting the GPS module to the unit
with the Y-adapter cable. 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.
This unit has reverse polarity protection. No damage will occur if the
power wires are reversed. However, the unit will not work until the
wires are attached correctly.
