Strike CNC (My first CNC router)

I'm wiring up the spindle and have another question.

There's 3 wires for the 3phase power along with a ground. Can I identify which pins are the correct one's for the power and which is the ground? I notice the GX16 connector that these spindles use have their pins marked 1-4. I assume 1-3 are power and 4 is ground?

Ant Think you'll find the 4th hisn't connected to anything.? Just test with circuit tester and you'll get no readings from that pin when connected either to any of the other pins or body.
