Marking; Emc Regulations - TECHTOP TD20 Series Product Manual

TD20 Series VFD
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 (
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.
