3-2 Installation guide

This is a general guide for locating and wiring the parts of the Explorer AP380 system. The instructions
for a particular part may have additional requirements.
3-2-1 Location guide
Do not mount any part where it can be used
as a handhold, where it will interfere with the
operation of the boat or where it might be
submerged.
Do not mount any part where it will interfere
with launching or retrieving
the boat.
Do not mount any part within 0.5 m (20") of
the plane of a radar antenna.
Mount the compass and gyro:
At least 1 m (3 ft) away from sources of
electrical signals or noise, such as the
batteries, high-current cables, other boat
cables, engines, fluorescent lights, power
inverters, radio or radar transmitters and
antennas.
At least 1 m (3 ft) away from equipment

Northstar Explorer AP380 System Installation and Operation Manual
3-2-2 Wiring guide
The Explorer AP380 system has two kinds of
cables:
The heavy-duty power supply and steering drive
usually require high-current cables:
Select the wire gauge from the wire size table
(see section 3-4-2).
Fit high-current cables at least 1 m (3 ft) away
from other electronic devices in
the boat.
Keep the cables as short as possible.
Twin 2 mm (#14) cable is supplied with the
Explorer AP380 system and can be used for
the high current cable if its gauge is suitable.
All the other cables are low-current:
Fit low-current cables at least 1 m (3 ft) away
from sources of electrical signals or noise,
such as the high-current cables, other boat
cables, engines, fluorescent lights, power
inverters and radio or radar transmitters and
antennas.
If the cable for the rudder feedback unit,
compass or gyro is too long, do not shorten
the cable; instead coil the cable up near the
main control unit.
The cable for the rudder feedback unit,
compass or gyro can be extended by
adding a 10 m (33 ft) extension cable and
coupling connector. Do not fit more than one
extension cable to each unit.
When fitting any type of cable:
Do not crush, pinch or strain the cable.
Secure the cable at regular intervals.
Ensure no connectors or exposed terminals
are in the bilge.
