9.4 Harmonic Component Regulation in the EU
9.4.1 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 9.4 below for details.

* When supplying three-phase 200 VAC power stepped down from a three-phase 400 VAC power line using a transformer, the level of
harmonic flow from the 400 VAC line will be regulated.
Note 1) A box (
) in the above table replaces S or E depending on the enclosure.
A box () in the above table replaces A or E depending on the shipping destination.
Note 2) Inverter types marked with √ in the table above are compliant with the EN61000-3-2 (+A14), so they may be connected to public
low-voltage power supply unconditionally.
Conditions apply when connecting models marked with "—". To connect them to public low-voltage power supply, you need to
obtain permission from the local electric power supplier. In general, you will need to provide the supplier with the harmonics
current data of the inverter. To obtain the data, contact your Fuji Electric representative.
9.5 Compliance with the Low Voltage Directive in the EU
9.5.1 General
General-purpose inverters are regulated by the Low Voltage Directive in the EU. Fuji Electric states that all our inverters with
CE marking are compliant with the Low Voltage Directive.
9.5.2 Points for consideration when using the FRENIC-MEGA series in a system to be certified by the
Low Voltage Directive in the EU
If you want to use the FRENIC-MEGA series of inverters in systems/equipment in the EU, refer to the guidelines on pages v
to viii.
