Power Connections - Eagle III Installation And Operation Instructions Manual

POWER CONNECTIONS

The Magna III works from a 12 volt DC system only. For the best results,
run the power cable directly to the boat's battery. Keep the power cable
away from other boat wiring, especially the engine's wires. This will give
the best isolation from electrical noise. If the supplied cable is not long
enough to reach the battery, splice #18 gauge insulated wire to it. If you do
extend the power cable, make certain to attach the in-line fuse holder
supplied with the Magna III to the battery or power source. This will protect
both the unit and the power cable in the event of a short. Use only a 3-amp
fuse.
You can also attach the power cable to an accessory or power buss,
however, you may have problems with electrical interference.
These units have 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.
