2 – Installation
The output of the internal voltage divider board is designed to prevent shock, energy and fire hazards, and is intended
to satisfy most codes and standards for external wiring outside the electrical enclosure.
All external wiring practices for an unprotected raw arc voltage should be reviewed and approved by the local
inspection authorities at the time of installation prior to operation and use. Raw arc voltage wiring terminals and
connections should not be exposed to accidental contact under normal and single fault conditions. External wiring
from an unprotected (that is, no voltage divider used in the power source) raw arc voltage routed inside conduit
between electrical enclosures will normally satisfy all electrical codes and standards worldwide. Failure to address
the hazards associated with live contact, accessibility and single fault failures to this unprotected output can result in
death or fire.
A voltage divider board inside the CNC protects only the CNC and does NOT protect the external interconnecting
wiring between the power source and the CNC. Overcurrent protection may be required to protect the user or machine
in fault conditions.
External wiring outside the electrical enclosure should be suitable for the installation and meet national and local
regulations (for example, NFPA 70 NEC, NFPA 79, Canadian Electrical Code, CSA/CAN E60974-1, IEC 60204-1,
BS 7671) or other codes or standards applicable to the installed site where the equipment will be operated.

WARNING!
SHOCK HAZARD, ENERGY HAZARD, AND FIRE HAZARD
Connecting directly to the plasma circuit for access to raw arc voltage increases the risk of shock
hazard, energy hazard, and fire hazard in the event of a single fault. The output voltage and the output
current of the circuit are specified on the data plate.
