2.4CONNECTION PROCEDURE
NOTE
In the following procedure the small wires must be stripped and tinned, and then connected to the proper connections in the Radar Junction Box, and to pins on the On/Off control switch. If you are uncertain of your skill in completing these tasks, it is strongly advised to obtain the services of a qualified technician. It is essential to the operation and reliability of your Radar that these procedures are accomplished properly.
1.Arrange the free end of the Antenna cable so that the wires will reach their intended points for connections.
2.The two large wires must reach a power panel; the five leads in the braided fabric jacket must reach the Radar Junction Box and the two remaining leads must reach the desired location for the On/Off control switch.
3.If the leads must go in different directions, first route the five leads in the fabric braid to the Junction Box. Then extend the shorter leads using the same size or larger size wire.
Please note that the power supply level at the Junction Box should be at least 12V since due the cable length the voltage at the Radar could drop below 10V.
The power supply cables should be of adequate diameter to feed the Radar, the Chart Plotter, the Junction Box and eventually any other instrument connected. The larger the diameter the better. A too small cable section could cause voltage drop over the cable with consequential overheating and danger of fire.
