11.4 Harmonic Component Regulation in the EU
11.4.1 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 1 kW 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 11.7 below for details.
