SECTION 3.0 SYSTEM CONNECTION NOTES
Interconnection of various units should be done carefully, in accordance with
interconnection diagrams (fig. 3.1 & 3.7) or damage to units may result. Particular
attention and care should be exercised in connecting input power to ensure that polarity is
observed and that the supply matches the 12 Volt DC Pilot requirements.
Before Pilot Installation, vessel's electrical system must be checked for proper transient
voltage suppression. Particularly, transients produced by alternator and starter motor
during engine start and shutdown to see that voltage never exceeds 50V where pilot will
be connected. Also, check any high current motor.
Electric Motor Driven systems, Power Windless, Refrigeration, Macerators, etc. produce
excessive transients. An electrical survey and any required corrections must be
performed before connecting any pilot component to the boats electrical service.
Since efficiency is the keynote of this unit, cabling from the battery must be of adequate
size to prevent excessive voltage drop and power loss. The following wire schedule is
recommended. Power cable length to 15 ft., #12 gage, 15 ft. to 30 ft., #10 gage, 30 ft. to
60 ft., #8 gage. All above specified wires are stranded copper and tinned. If drive unit
power cables are extended, use above table in calculating wire gage.
