NOTE

All wiring is best kept as short as possible. If the power leads must be

extended, use a high-quality, marine-grade cable sized for up to 10 amps

of current. To minimize voltage drop, choose a wire gauge as follows:

Length Wire Gauge

Up to 1.5m (4.9ft) 1.6 mils (#14)

Up to 3.0m (9.8 ft) 2.0 mils (#12)

Up to 5.0m (16.4 ft) 2.6 mils (#10)

Up to 6.0m (19.7 ft) 3.3 mils (#8)
