In the MultiPlus II GX manual it is written to follow the instructions below when connecting the AC input:
Left to right: N (neutral), PE (earth/ground), L (phase)
In my setup I have a 3kW inverter generator as AC in, but I cannot understand which is the neutral and which is the phase as the output of my generator is a female plug, on which the plug can be inverted from time to time.
Which is the proper connection in this case?
Thanks a lot
