A.1.2.3 Derating of the carrier frequency
The setting range of carrier frequency in different power rating is different. The rated power is defined as its
factory carrier frequency. The inverter has to derate 10% for every additional 1kHz carrier frequency if the
carrier frequency exceeds the factory value.
A.2 CE
A.2.1 CE mark
The CE mark is attached to the drive to verify that the drive follows the provisions of the European Low Voltage
(2006/95/EC) and EMC Directives (2004/108/EC).
A.2.2 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.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
usage, 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 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:
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 drive is installed according to the instructions reference in this manual.
 In a domestic environment, this product may cause radio inference, in which case
supplementary mitigation measures may be required.
A.3.2 Category C3
The immunity performance of the drive complies with the demands of IEC/EN 61800-3, second environment.
The emission limits are complied with the following provisions:
