1) Processing cables
When you directly connect with the ship's power supply without using the optional
rectifier, measure the voltage between the hull's earth and the positive side of ship's
power supply, and the hull's earth and the negative side of this. And check voltage of
50 volts or more is not required.
If voltage of 50 volts or more is required, take the measures which do not require 50
volts or more between the above mentioned terminals.
Connection without taking the measures causes system failure or accident.
2) Connecting the cable to the radar process unit
Connect the CFQ-6911 connector to the connector for which "POWER" is engraved at the rear of the
radar process unit cabinet. Turn the plug attached to the connector until it cannot be turned any further.
The CFQ-5436 is connected here.
