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 spply, 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.
