Safety requirements. Functional.
A.5.1 CE marking
The CE mark is attached to the drive to verify that the drive follows the provisions of the
European Low Voltage and EMC Directives.
A.5.2 Compliance with the European EMC Directive
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 regulations
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 1000 V and used in the first
environment.
Inverter of category C2: inverter of rated voltage less than 1000 V other than pins, sockets
and motion devices and intended to be installed and commissioned only by a professional
electrican when used in the first environment.
Note: IEC/EN 61800-3 in EMC standard doesn’t limit the power distribution of the inverter,
but it defines the ustep, installation and commission. The professional electrician has
necessary skills in installing and/or commissioning power drive systems, including their EMC
aspects.
Inverter of category C3: inverter of rated voltage less than 1000 V and used in the second
environment other than the first one
Inverter of category C4: inverter of rated voltage more than 1000 V or the nomninal current is
above or equal to 400A and used in the complicated system in second environment
