A.5.2 Complicable with EMC regulations
The EMC Directive defines the requirements for immunity and emissions of electrical equipment used
within the European Union. The EMC product standard (EN 61800-3:2004) covers requirements
stated for drives. See section EMC regulations .
A.6 EMC regualtions
EMC product standard (EN 61800-3:2004) contains the EMC requirements to the inverter.
First environment: domestic environment (includes establishments connected to a low-voltage
network which supplies buildings used for domestic purposes).
Second environment includes establishments connected to a network not directly supplying domestic
premises.
Four categories of the inverter:
Inverter of category C1: inverter of rated voltage less than 1000V and used in the first environment.
Inverter of category C2: inverter of rated voltage less than 1000V other than pins, sockets and motion
devices and intended to be installed and operated only by a professional electrican when used in the
first environment.
Note: IEC/EN 61800-3 in EMC standard does not limit the power distribution of the inverter, but
it defines the usage, installation and commissioning. The professional electrician needs the
skills in installing and/or commissioning electrical drive systems, including EMC aspects.
Inverter of category C3: inverter of rated voltage less than 1000V and used in the second
environment other than the first one
Inverter of category C4: inverter of rated voltage more than 1000V or the rated current is above or
equal to 400A and used in the complicated system in second environment
A.6.1 Category C2
The emission limits comply with the following provisions:
1. The optional EMC filter is selected according to the options and installed as specified in the EMC
filter manual.
2. The motor and control cables are selected as specified in this manual.
3. The inverter is installed according to the instructions given in this manual.
4. For the maximum motor cable length with 4kHz switching frequency, see EMC compatibility and
motor cable length .

In a domestic environment, this product may cause radio interference, in which
case supplementary mitigation measures may be required.
A.6.2 Category C3
The immunity performance of the drive complies with the demands of IEC/EN 61800-3, second
