I upgraded because i need to use 1/2" shank tools. I received the spindle w/o instructions. The power connector on the top of the 2.2KW spindle has 4 wires. The 1.5KW has only 3 wires and they are all white. The 2.2KW has black, brown, red, and a blue wire. I need to know which wires to use to make the spindle run. Both connectors have 4 female inputs. I don't know how to connect them correctly.
Please help!!
