Just got this wired up, easy to follow instructions to get it up and running. I used a kettle lead for the power, stripped and connected to the single phase input. Just a normal 3 core wire to the spindle as I'm going to run the cable along my extraction hose, if you want it in the drag chain or near other low voltage cables you'll need some shielded cable for interference. Just want to connect the earth from the kettle lead to the aircraft plug on my spindle then its ready to go on my machine. Obviously I can't comment on the longevity of the unit, I'll have to come back and update later but I'm very happy with this so far.I'm using this with a Vevor 1.5kw air cooled spindle on a standard Workbee 1015.
