10.4 Harmonic Component Regulation in the EU
10.4.1 General comments
When you use general-purpose industrial inverters in the EU, the harmonics emitted from the
inverter to power lines are strictly regulated as stated below.
If an inverter whose rated input is 1kW or less is connected to public low-voltage power supply, it is
regulated by the harmonics emission regulations from inverters to power lines (with the exception
of industrial low-voltage power lines). Refer to Figure 10.5 below for details.
