Power connections for the X50 DS sonar unit

(direct battery connection shown).

If possible, keep the power cable away from other boat wiring, espe- cially the engine's wires. This will provide the best isolation from elec- trical noise. The power cable has two wires, red and black. Red is the positive lead, black is negative or ground. Make sure to attach the in- line fuse holder to the red lead as close to the power source as possible.

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.

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 war- ranty.

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.
