Looks like 230 to me.
One leg into the left group (123 which connect to the blues)
One leg to the right group (4,5 which connect to the reds)
Does that terminal block have screw lugs? Please dont tell me that the wiires just push in there :jester:
In the US we have 120 and 240 stuff. We would use L1 and L2 (line 1 and line 2) for 240 stuff and L1 and N for 120 stuff.
Apparently things in Europe are all 240 and they refer to one leg as neutral ????
Sorry to step in this late.,
However the termail block do have setscrew lugs below the photo you can not able see it from the photo angle.,
As far for European voltage C'est { it is } 230-240 volt
line to netural format and for line to line voltage it is 400-415 volts
Now for the OP you will have to concat the manufacter to verify to work with North America system due the North America 240 volts are line to line voltage format.
I will just ring it out the netural side to the grounding side to make sure it is not hook up otherwise you will have issue it will arise.
{ Look at the nameplate they are designed to work both single and triphase supply so I don't think you will have issue but verify with manufacter to make sure . }
Merci,Marc
Yeah In case you wondering where I am .,, I am still in Paris France
