13.4 Regulations on Harmonics in Europe
13.4.1 General
When general-purpose inverters, which are industrial products, are used in Europe, harmonics are
regulated as follows.
Inverters with an input power of 1 kW or below connected to commercial low-voltage power lines are
subject to the harmonic regulations. Note that inverters connected to industrial low-voltage power lines fall
outside the regulations. (Refer to Figure 13.4-1)

Y: Allowed to be connected to a commercial low-voltage power line as the standard of EN61000-3-2
(+A14) is satisfied.
N: The standard of EN61000-3-2 (+A14) is not satisfied. If you wish to connect the inverter to a
commercial low-voltage power line, you need to obtain permission from your local power company. If
you need the data of harmonic current, contact your Fuji Electric representative.
Note 1: A box () in the above table replaces an alphabetic letter depending on the type.
Note 2: A power source of three-phase 400 V is transformed to supply a power source of three-phase 200
V to the inverter, then the harmonics that flow into the power source of 400 V are evaluated.
