A.2 Marking
A.2.1 CE marking
The CE mark is attached to the inverter to verify that the inverter follows the provisions
of the European Low Voltage (2006/95/EC) and EMC Directives (2004/108/EC).
A.2.2 UL and CUL marking
The UL and CUL marks are attached to the inverter to verify that the inverter follows the
provisions of the UL508C and C22.2 No. 274-13.
A.2.3 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 inverters. See section EMC regulations
A.3 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 electrician 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 upstage, installation and commission. The professional
electrician has necessary skills in installing and/or commissioning power drive systems,
including their EMC aspects.
