'Frequency Changers', Frequency Generators and Variable Speed electrical drives, having all the following characteristics: (a) Multiphase output power of 10 W or greater; (b) Capable of operating at a frequency of 600 Hz or more; and (c) Frequency control better (less) than 0,2 %. Technical Note: 'Frequency Changers' includes frequency converters and frequency inverters. Notes: 1. Item III.A3.005 does not control frequency changers that include communication protocols or interfaces designed for specific industrial machinery (such as machine tools, spinning machines, printed circuit board machines) so that the frequency changers cannot be used for other purposes while meeting the performance characteristics above. 2. Item III.A3.005 does not control frequency changers specially designed for vehicles and which operate with a control sequence that is mutually communicated between the frequency changer and the vehicle control unit.
