SECTION TWO: Installing and wiring the

972

The Northstar 972 uses a processor module that must be mounted in a protected location and a

control head that can be exposed to water splash. A DVI video cable and a control cable feeds

communication between the processor and the control head. All interface wiring connects to the

processor. Power wiring connects to the processor and control head.

Because the control head uses a 15-inch LCD, making the unit large and heavy, it is designed to be

flush-mounted, with no provision for yoke-mounting.

Northstar recommends bench-testing the 972 with a GPS antenna before installing it onto the vessel.

Bench testing ensures that the equipment is fully operational, and lets the unit collect the current

almanac and ephemeris data and a local position fix, which results in less on-board installation time.

WARNING!

Before starting the installation, be sure to turn electrical power

off. If power is left on or turned on during the installation, fire,

electrical shock, or other serious injury may occur.

Be sure that the voltage of the power supply is compatible with

the 972's voltage rating of 10 to 32 volts DC. Connecting to the

wrong power supply can cause fire or damage to the equipment.

Be sure to ground the equipment to prevent electrical shock and

mutual interference.

Be sure to use a 7-amp fast-blow fuse in the supplied power

cable. Using the wrong fuse can cause fire or damage to the

972.
