NVUM5-SP Power Supply

Hello everyone,
This is my first time building a CNC milling machine and I'm using NVUM5-SP controller. Does anyone know how i can power up the board?
Currently, I'm only using motor drive pins, limits+/-, emergency stop and tool probe pins. The limit switches are connected to 12V pins & and input pin, (eg. INP4)
The only pins that are left are "12V" , INP1, INP2. can i connect the power supply to these pins using INP1 as ground?
Attached is the wiring that's found in the manual.
