Tomorrow I will be putting some power to my mill and I see that the terminals I need to power on are right on that rotary switch that operators normally flip to turn a mill on or off.
This CNC mill is wired for the standard 200+V 3 phase power. My question here is does it matter what legs I put on those terminals? They are labeled "L1, L2, L3" and then there is a gound as well. There is no indication anywhere that I need to put the wild leg in any one of those terminals. My assumption is that I can simply go ahead and stuff the three lines in there and the only problem may be that the spindle runs backward. And if that happens, I can simply take any two of those wires and switch their terminals.
I have attached a picture of what my cabinet looks like. From what I can see, it looks to be a pretty typical setup.
