Subject: Laranzato Green 2 wiring issue
 

Just purchase a Laranzato Green 2 ? espresso machine.  it came without a line cord. reading the nameplate I find it would like to see 20 Amps at 230 volts service.  when opening the machine it looks like it may have been designed for three phase service.   there is a N connection which in the US would indicate neutral. then three L connections 1, 2 and three.  the three L or I assume line connections are jumpered together with what appears to be factory jumpers.   that kinda indicates I should be connecting my 20 amp single phase USA line cord with one of my two hot wires  to the N and the other side of my 20 amp service wire to the jumpered 1,2 and three "L" connections. then ground to the ground connector.  however......  the "N" worried me since we normally connect "N" in the US to neutral which winds up "ground" in most services at the main service panel.  anyone have input on this.  of course, no manual and no manual available on line as best I can tell.  I don't want to damage the machine.  thanks in advance for any help.  Richard

NORMALLY

following Italian/european color coding
to adapt espresso machines for here

every hot color which could be

grey, black, brown get connected together to do one leg

the blue the other hot leg

the green/striped yellow the ground
