Safety Overview
Any machine tool is potentially dangerous. The automation inherent in a CNC machine presents added risk not present in a manual mill. Tormach CNC mills can deliver sufficient force to break brittle tools, crush bones, and tear flesh.

WARNING! Electrical Shock Hazard: Be sure to power off machine before making any electrical modifications. Failure to do so may result in serious injury or death.
Input Power: The PCNC 1100 has two electrical power inputs, primary and secondary. The 230 VAC primary input supplies axis and spindle power, while the 115 VAC secondary input supplies power to the PathPilot® controller and accessory outlets. The wiring and electrical components associated with either circuit are capable of delivering lethal electrical shocks. Care should be exercised when working inside the electrical cabinet.
Grounding: Both primary and secondary power inputs must be grounded. Do not assume during installation that a wall outlet is properly grounded. Check continuity between the machine frame and true earth ground (metal water pipe or similar) to ensure a good ground connection.
Ground Fault Interrupter: A Ground Fault Interrupter or GFI (also known as a Residual Current Circuit Breaker or RCCB) outlet must be used to supply power to the 115 VAC power input for the secondary input.
Electrical Cabinet: Never operate the machine tool with the electrical cabinet open. Never allow coolant pump to operate with the electrical cabinet open. Do not allow the coolant system to flow coolant directly at the electrical cabinet or the operator panel. Neither the electrical cabinet nor the operator panel controls are hermetically sealed against liquids.
...
Retained Electrical Power: Electronic devices within the electrical cabinet may retain dangerous electrical voltage after the power is off.
