Certifications
European EMC guidelines
If the VAU4/3 frequency converter is installed and operated according to the recommendations
of these operating instructions, it fulfils all requirements of the EMC regulations according to
the EMC product standards for motor driven systems EN 61800-3.
UR certification
(Use in North America)
“Suitable for use on a circuit capable of delivering not more than 5000 rms sym-
metrical amperes, 380…480Volts (three phase)” and “when protected by J class
fuses.” as indicated.“
The VAU4/3 frequency converter is equipped with a motor overload protector.
