Power connections for X102C and X107CDF sonar units.
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. This unit
could be damaged to a point 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.
An optional 8-foot, CA-4 external power cable with a cigarette lighter
adapter is available from Lowrance.
NMEA 0183 Cable Connections
NMEA is a standard communications format for marine electronic
equipment, mainly navigation equipment. Your sonar unit cannot cur-
rently communicate with the NMEA 0183 format, so the Data cable
wires will not be used.
