Order the 2.2kW Water Cooled Spindle for more efficient, quieter CNC routing. Do not attempt to wire your VFD or spindle on your own. Consult with a professional electrician before following the diagram. Earth pin must be properly connected!

COOLING and Wiring
Spindles need to be cooled and this spindle uses water for this purpose. More importantly, this aspect of water cooling does not allow air movement to cool the spindle (as opposed to routers that move air through the router to cool by convection). Water cools the spindle using conduction (heat transfer through contact). This is important because, as opposed to air movement, water cooling will not blow the dust all over the shop, and the dust and chips left over by the milling and cutting process can be removed with a dust collector or vacuum.
The ports for the water cooling tubes or hose is located at the back of the spindle. The port fitting will accept a tube or hose that has a 1/4" (.25 inch) inside diameter and an outside diameter of 3/8" (.375 inch). Either port can be used for in or out. It's just important that the water flow through the body of the spindle.
The sound level from a spindle is extremely low as compared to routers. In fact, the sound from a spindle is quieter than the actual cutting and milling action from the end mill, and much quieter than a router.
SPINDLE Inverter Wiring
Spindles required the use of a VFD (Variable Frequency Drive) to function. These VFDs are also called spindle inverters. The VFD takes the power from the wall and creates a frequency with voltage and current to spin the spindle. The frequency can be controlled to control the RPM of the spindle.
Pin1 to U
Pin2 to V
Pin3 to W
Pin4 to Earth ( This pin is mandatory! )
NOTE: Do not directly plug it into electricity power, Spindle can be connected only to Frequency Inverter!
