Specifying Adjustable Frequency Drives For Electromagnetic Compatibility
Electromagnetic compatibility (EMC) is the ability of electrical/electronic equipment to operate in its installation environment while neither causing nor experiencing electromagnetic interference (EMI). EMI is any interference with normal equipment operation caused by abnormal energy entering the equipment either by conduction though wiring connections or by radiated wave reception. Radiated EMI is also called radio frequency interference (RFI). Conducted EMI is also called high-frequency line noise.
FCC Rules and Regulations - Part 15 of the Federal Communications Commission (FCC) rules and regulations covers unlicensed equipment that emits radio frequency energy. Part 15 would apply to any AFD as an "incidental radiator." The operation of any equipment covered by Part 15 is subject to the general conditions of operation listed under paragraph 15.5.
