POWER CONNECTIONS - All units
This unit 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. You can attach the
power cable to an accessory or power buss, however, you may have
problems with electrical interference. Make certain to attach the in-line fuse
holder to the positive lead as close to the battery or terminal strip as
possible. This will protect both the unit and the power cable in the event of
a short. Use a 3-amp fuse.
WARNING!
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.
