Installation
This chapter describes all the steps you must follow while doing the physical installation of
the P Series Autopilot System on your boat.
Each of the standard components of a P Series system is described – both physical mounting
& electrical wiring – and then some final checks are given. Commonly-used accessories are
also described. Many components come with their own specific instructions, and you should
pay attention to those, as well.
Basic Requirements
Please refer to the
Warranty Information
section of this manual before proceeding with
installation.
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 & safety hazards, in accordance with local electrical codes.
Steering System
To obtain the best performance from your autopilot system, your boat’s steering system must
be in good working order. The hydraulic system should be bled, and should be operating
with minimal play.
When installing a Reversing Motor Pump, a Constant Running Pump, or an Engine Driven
Pump, it is recommended that you install shutoff valves on all hydraulic lines between the
Pump and the steering system.
Power Supply
For reliable operation of your Autopilot, your boat’s power supply system must have an
adequately-breakered, or fused, DC (direct current) power supply at a nominal voltage of
either 12 or 24 volts. If the circuits are fused, a power 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 tightening the small screws
of the wire clamps in the plugs which mate with the SPU’s pin-receptacle connectors.
Fasteners
In general, fasteners are not supplied with the system – since different surfaces need various
types of fasteners.
But, no matter which types are best suited to your boat, ComNav strongly recommends that
you use non-corroding hardware to secure all equipment in the system.
