Preface

• Chips and dust from certain materials (e.g., magnesium) can be ammable. Fine dust from

normally non-ammable materials may be ammable or even explosive.

• Chips, dust, and vapors from certain materials can be toxic. Always check the Materials Safety

Data Sheet (MSDS) for each material.

IMPORTANT: It is the responsibility of the employer/operator to provide and ensure point of operaon

safeguarding per the following:

• OSHA 1910.212 – General Requirements for All Machines

• OSHA 1910.212 – Milling Machines, point of operaon safeguarding

• ANSI B11.22-2002 Safety Requirements for Turning Centers and Automac Numerically

Controlled Turning Machines

• ANSI B11.TR3-2000 Risk Assessment and Risk Reducon – A Guideline to Esmate, Evaluate,

and Reduce Risks Associated with Machine Tools

• Safety Requirements for Construcon, Care, and Use of Drilling, Milling and Boring Machines

(ANSI B11.8-1983). Available from American Naonal Standards Instute, 1430 Broadway,

Electrical Safety

WARNING! Electrical Shock Hazard: Be sure to power o machine before making any electrical

modicaons. 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

installaon that a wall outlet is properly grounded. Check connuity between the machine frame

and true earth ground (metal water pipe or similar) to ensure a good ground connecon.

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.
