Other Parts Required; Installation; Installation Sequence - NorthStar EXPLORER AP380 Installation And Operation Manual

2-2 Other parts required

Power supply: The Explorer AP380 system
requires two power supplies, both nominally 12
V DC:
A heavy duty supply for the steering drive
A light duty supply for the Explorer AP380
system electronics and display unit; this
supply also powers any additional display
units and other instruments.
The power supplies require one or two switches
and fuses or circuit breakers (see section 3-4).
Steering drive: The Explorer AP380 system can
power a hydraulic pump, constantly running
pump set, hydraulic linear drive or mechanical
drive rated at 12 V DC and up to 20 A.
Rudder linkage: To link rudder to rudder
feedback unit (see section 3-5).
For wiring, see Select Wire Table in section 3-4-2.

3 Installation

Correct installation is critical to the performance
of the unit. It is vital to read this manual and the
documentation that comes with the other parts
before starting installation.
The MCU600 is not waterproof. Mount the
unit in a dry place.

3-1 Installation sequence

The recommended installation sequence is:
1 Read this manual and the documentation
that comes with the other parts.
2 Plan the installation: select where the
equipment and wiring will be installed (see
section 3-2).
3 Install the MCU600 (see section 3-3).
4 Install the steering drive and wire the heavy
duty and light duty power supplies
(see section 3-4).
5 Install the rudder feedback unit
(see section 3-5).
6 Install the compass (see section 3-6).
Northstar Explorer AP380 System Installation and Operation Manual
External beepers or lights (optional ):
The external output is switched to ground,
30 V DC and 250 mA maximum. If the beepers
and lights require more than 250 mA total, fit a
relay.
Other marine instruments (optional): Wind,
speed or GPS instruments can be connected (see
section 1-2).
Other parts: For systems of several instruments,
wiring and connectors are required. Northstar
junction boxes can simplify wiring several
Northstar instruments together (see section 1-2
or the NavBus Installation and Operation Manual).
Coupling connectors and 10 m (33 ft) extension
cables are available to extend the rudder
feedback unit, compass or gyro cables. Do not fit
more than one extension cable to each unit.
For more information, consult your
Northstar dealer.
The Explorer AP380 system display unit is
waterproof.
The compass, gyro and rudder feedback
unit are completely waterproof.
Ensure that any holes that you cut will not
weaken the boat's structure. If in doubt, consult
a qualified boat builder.
7 Install the gyro (see section 3-7).
8 Install the display unit and any other marine
instruments that will be used with the
Explorer AP380 system (see section 3-8).
9 Carry out the dockside setup
(see section 4).
10 Carry out the sea trials (see section 5).
If you are unsure where a part should be
installed, mount and wire the part temporarily,
without cutting holes in the boat. After the sea
trials have been completed, install and wire the
part permanently.
