400W Spindle Wiring





Safety Statement

The author of this document is not liable or responsible for any accidents, injuries, equipment damage, property damage, loss of money or loss of time resulting from improper use of electrical or mechanical or software products.

Assembling electrical and mechanical CNC machine components like power supplies, motors, drivers or other electrical and mechanical components involves dealing with high voltage AC (alternating current) or DC (direct current) and other hazardous items which can be extremely dangerous and needs high attention to detail, experience, knowledge of software, electricity, electro-mechanics and mechanics.

BEFORE MAKING ANY CONNECTIONS OR DISCONNECTIONS POWER MUST BE REMOVED FROM THE DEVICE AND THE CONTROLLER. FAILURE TO DO SO WILL VOID ANY AND ALL WARRANTIES.

Before starting please read though all the instructions.

Note : Any Mains power connections must be installed by a Licensed electrician or suitability qualified person.

Errors and omissions excepted

The electronic components in the 400W Spindle Bundle include:

  • 1 x Air Cooled CNC Spindle 400W
  • 1 x PWM Speed Controller
  • 1 x Power Supply – 48V 350W
  • 5 meters DC Power Cable – 22AWG

NOTE: There may be some variations based on board layout or etc, but the essential connections remain consistent. That is, +ve and -ve from power supply to PWM Speed Controller and +ve and -ve from PWM Speed Controller to Spindle.
