    Default Wiring help for new PRS Alpha

    Hi all,

    One wire to go and my electrician is a little stumped. After viewing the photo below, does anyone know where the neutral should be wired? It is a 3phase PRS Alpha in Australia.

    IF this is your 240, and it looks like your 3PH is hooked up correctly on the left assuming all 3 of your wires are hot, The hot 240 would go on the blue contactor (the connector next to the 3 phase) and the neutral goes in the other one. Don't forget your grounds (earths to you)!!
    When you first start your spindle, just turn it on for a couple of seconds. If it turns the wrong way then change around 2 of the 3PH wires.

    Andrew,
    The forum is not a place for high voltage electrical advice.

    Please contact ShopBot via telephone during business hours, or send SB Support an email: support@shopbottools.com

    Yep - I get it it...but you should have electrical diagrams in the manilla envelope in the control box that shows where everything goes. I'd hate to see you let out the magic smoke before you got a chance to use it....

    Does electricity flow upside down in Australia ??

    The whole thing looks upside down from here...
    The decimal point seems to be the most important on the z axis... x & y not so much....
    ShopBot... Where even the scraps and things you mess up and throw away are cool....
