2.2.4 Electrical Noise
Primary power should be provided by a dedicated circuit. At the minimum, it should be isolated from
electrically-noisy devices. In parcular, high-inducve loads from vacuum cleaners, air compressors,
etc., can be troublesome and the source of controller malfuncon.
At sites where this is not possible, a double-conversion uninterrupble power supply (UPS) should
be considered for 115 VAC circuits.
2.2.5 Options for Electrically Non-conforming Sites
The following device may be considered for sites that do not conform to the electrical requirements
detailed in this secon. Consult with an electrician to determine suitability for the specic site.
• Step-up/Step-down Transformer (PN 32009): used to reduce 230 VAC line voltage to 115 VAC,
as required by the PCNC 440; commonly used for PCNC 440 mills located outside of the USA
and Canada.
