Harmonic Component Regulation in the EU

8.4.1 General comments

When general-purpose industrial inverters are used in the EU, the harmonics emitted from inverters to the
power lines are strictly regulated as stated below.
If an inverter whose rated input is 1 kW or less is connected to the public low-voltage power supply, it is
regulated by the harmonics emission regulation IEC/EN 61000-3-2. If an inverter whose input current is 16 A or
above and 75 A or below is connected to the public low-voltage power supply, it is regulated by the harmonics
emission regulation IEC/EN 61000-3-12.
Note that connection to the industrial low-voltage power lines is an exception. (See Figure 8.3.)

8.4.2 Compliance with IEC/EN 61000-3-2

The FRN0.75AR1 -4 satisfies the IEC/EN 61000-3-2, so it can be connected to the public low-voltage power
supply.

8.4.3 Compliance with IEC/EN 61000-3-12

To bring the FRN0.75AR1 -2
FRN0.75AR1 -4 (FRN001AR1 -4U) to FRN37AR1 -4
IEC/EN 61000-3-12, connect them to the power supply whose short-circuit ratio Rsce is 120 or above.
8.5

Compliance with UL Standards and Canadian Standards (cUL certification)

8.5.1 General

Originally, the UL standards were established by Underwriters Laboratories, Inc. as private criteria for
inspections/investigations pertaining to fire/accident insurance in the USA. The UL marking on Fuji products is
related to the UL Standard UL508C.
cUL certification means that UL has given certification for products to clear CSA Standards. cUL certified
products are equivalent to those compliant with CSA Standards. The cUL marking on Fuji products is related to
the CSA Standard C22.2 No. 14.

8.5.2 Considerations when using FRENIC-HVAC in systems to be certified by UL and cUL

If you want to use the FRENIC-HVAC series of inverters as a part of UL Standards or CSA Standards (cUL
certified) certified product, refer to the related guidelines described on pages xi to xx.
