Advance Protection Against EMI/RFI Conducted and Radiated Emissions: New advance controls and electronic equipment may create EMI/RFI emissions, which result in conducted and radiated noise. This is particular true in industrial and commercial environments, which see ever increasing uses of Adjustable Speed Drives and other modern sources of noise generators. In turn, other systems may be susceptible to the conducted or radiated EMI/RFI interference and suffer shutdown or irregular process control errors.
