Installation

Technical Requirements

The following are the basic technical requirements that should be met before

installation of the Navigator G2 on your vessel.

Caution

Please refer to the Warranty Information this manual before proceeding

with installation of the Navigator G2.

Hazard warning!

CAUTION!

Extreme caution is advised when using tools powered by alternating

current (AC) from main AC supply circuits, regardless of whether the

supply circuits are “indoor”, “outdoor”, “marine” or “industrial” rated.

Water, especially sea water, is an

EXCELLENT conductor of electricity,

and can complete a path to AC Ground through a person’s body,

causing injury or death, if a tool malfunctions or short-circuits.

⇒ Battery powered tools are STRONGLY recommended ⇐

If AC tools are used, they MUST be plugged into a circuit that is

adequately protected against Ground Faults and other safety hazards,

in accordance with local electrical codes.

Power Supply

For reliable operation of your Navigator G2, your vessel’s power supply system must have an

adequately-breakered, or fused, DC (direct current) power supply at a nominal voltage of

either 12 volts. If the circuits are fused, a switch should also be provided. Ensure that

adequate wire sizes are used to handle the expected maximum currents.

Special Tools

A slot screwdriver with a tip size of ~2.5 mm (0.1”) is required, for opening the spring loaded

termination connectors inside the Distribution Unit.

Other general-purpose tools such as a portable drill, pliers, wire cutters, screwdrivers, wire,

mounting bolts and wrenches will also be required.
