Per the installation manual figure 4a, when the boat is floating the connect the PE wire coming from the input PE terminal J34A to male push-on connector J34A1 so that the input and output are isolated from each other.
If the boat is on shore for maintenance, the PE connector in the boat needs to be disconnected from J34A1 and then connected to J34 (shown in green) For safety reasons.
I would like to understand the safety reasons for this wiring change? Can more information be provided? This is an annoying thing to remember to do when hauling/launching.
If it must be done, can I install a remote switch so we don't have to play with the wires in an inconvenient location every time the boat is on land and relaunched?
