6 Installation and setup
Correct installation is critical to the performance of the unit. It is vital to read this section of the manual and the documentation that comes with the other parts before starting installation.
The Explorer D310 can:
Drive external beepers or lights for the alarm.
Send and receive data from other Northstar instruments connected via NavBus. Settings for alarms, units, calibration and backlighting are shared (see section
Send and receive NMEA data from other instruments (see section
CAUTION
The unit is waterproof from the front. Protect the rear of the unit from water, or else water might enter the breathing hole and damage the unit. The warranty does not cover damage caused by moisture or water entering the back of the unit.
Ensure that any holes that you cut will not weaken the boat’s structure. If in doubt, consult a qualified boat builder.
The choice, location, angle and installation of the transducers is the most critical part of the installation. If they are not correct, the unit can not perform at its designed potential. If in doubt, consult your Northstar dealer. Plastic through hull transducers are usually unsuitable for wood hulls. If in doubt, consult a marine surveyor or marine engineer.
6-1 Installation
Explorer D310 display unit
1 Choose a location for the display unit that is:
Easily seen and protected from damage.
At least 100 mm (4”) from a compass and at least 500 mm (1.65 ft) from a radio or radar antenna.
Away from engines, fluorescent lights, and power inverters.
Accessable from behind; the minimum clearance required at the back is 50 mm (2”) (see mounting diagram).
With the back of the unit protected from moisture.
2The unit must mount on a flat panel which is less than 20 mm (0.75”) thick. Stick the mounting template in place. Drill a 50 mm (2”) fixing hole through the centre hole in the template. Note that the template allows space around the unit for the protective cover.
3Remove the fixing nut from the back of the unit. Insert the stud at the back of the unit through the mounting hole. Hand tighten the fixing nut.
Transducers
1If the Explorer D310 does not come with a transducer, choose a suitable transducer (see section
2Choose a suitable location for the transducer and install it by following the instructions in the Transducer Installation manual.
3Fit the cables between the transducer and the display unit:
Keep the cable away from other cables, engines, fluorescent lights, power inverters and radio or radar transmitters.
Ensure no connectors lay in the bilge.
If necessary, extend the cable by adding extension cables.
Do not cut the cable on any depth transducer.
Secure the cable at regular intervals.
4Connect the transducer to the display unit connector.
