Class B
The EN 61800-3 standard requires that the following warning be provided for drive
systems that do not comply with category C1 specifications:
This product can produce high-frequency interference emissions that may necessitate
targeted interference suppression measures in a residential or office environment.
2.9.2 Line harmonics requirements
The product is a device for professional applications as defined by EN 61000-3-2. The
following generic standards apply when establishing a connection to the public
power grid:
▪
EN 61000-3-2
for symmetric, three-phase devices (professional devices with a total power of up
to 1 kW)
▪
EN 61000-3-12
for devices with a phase current of between 16 A and 75 A and professional
devices from 1 kW up to a phase current of 16 A.
2.9.3 Interference immunity requirements
In general, the interference immunity requirements for a frequency inverter hinge on
the specific environment in which the inverter is installed.
The requirements for industrial environments are therefore higher than those for
residential and office environments.
The frequency inverter is designed such that the immunity requirements for
industrial environments and, thus, the lower-level requirements for residential and
office environments, are met and fulfilled.
The following relevant generic standards are used for the interference immunity test:
▪
EN 61000-4-2: Electromagnetic compatibility (EMC)
– Part 4-2: Testing and measurement techniques – Electrostatic discharge
immunity test
▪
EN 61000-4-3: Electromagnetic compatibility (EMC)
– Part 4-3: Testing and measurement techniques – Radiated, radio-frequency,
electromagnetic field immunity test
▪
EN 61000-4-4: Electromagnetic compatibility (EMC)
– Part 4-4: Testing and measurement techniques – Electrical fast transient/burst
immunity test
▪
EN 61000-4-5: Electromagnetic compatibility (EMC)
– Part 4-5: Testing and measurement techniques – Surge immunity test
▪
EN 61000-4-6: Electromagnetic compatibility (EMC)
– Part 4-6: Testing and measurement techniques – Immunity to conducted
disturbances, induced by radio-frequency fields
