hi, can anyone help. I purchased one of the little 500w spindle and power unit off ebay. it comes complete with bracket and speed control. The thing is the power unit is all marked up in Chinese and apart from knowing what set of wires goes to what unit. I have know idea which is live or natural/ can anyone please help me out here. thanks, terryAttachment 25330
If it is not marked up. Take the fuse out then check with a meter which of the two terminal on the right hand side is connected to the fuse carrier. Connect the one that is connected to the fuse holder to the mains live and the other to neutral.Quote:

as I can not read Chinese either
I would check to see if the fuse is connected to one of the power terminals
if it does as I would expect that will be the Live (hot) terminal
I notice that there is no Earth terminal ! - a feature of many Chinese tools
at the very least I would connect the the mains Earth to the metal enclosure

hi. thanks for replies. I have got power to the spindle using the power unit that came with the spindle as per pic. but I can only get it to work when it is the only item in the power change. I have tried to power it from the machines mains input socket but know joy. it will only work if its the only unit. I am not great with elecs and I was hoping to just have the one mains plug socket to the machine. is there something I am missing here. I am only using live and natural feeds to the spindle power unit as there are only two inputs. the machine also as earth connected at the mains input. do you think that if I fitted a terminal block from the machines mains input socket and then to the two cnc driver power units and also the spindle power supply unit it would work.
I think you are in dangerous ground here.Quote:

Yes please be careful !
Sounds like you might have wired them in all in series ? They need to be in parallel.
Based on what you have written I would say get someone experienced over to see it first hand before fiddling any more
Also they are live and neutral not natural
