Installing The Electrical Power Supply
The system requires four separate 3 phase power supplies. Power must be supplied to the CNC unit, the laser, the chiller and the dust collector. Power should be supplied from a line separate from those for welding machines and other processes that produce electrical noise. Ground rods must be installed next to the laser and CNC cabinets.
