A.2 Marking
A.2.1 CE marking
The CE mark is attached to the VFD to verify that the VFD 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 VFD to verify that the VFD 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 VFDs. See section
EMC regulations
A.3 EMC regulations
EMC product standard (EN 61800-3:2004) contains the EMC requirements to the VFD.
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 VFD:
VFD of category C1: VFD of rated voltage less than 1000 V and used in the first environment.
VFD of category C2: VFD 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 VFD, 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.
VFD of category C3: VFD of rated voltage less than 1000 V and used in the second environment other
than the first one
VFD of category C4: VFD of rated voltage more than 1000 V or the nominal current is above or equal to
400A and used in the complicated system in second environment.
A.3.1 Category C2
The emission limits are complied with the following provisions:
