Emc Regulations - Salicru CV50-008-4F User Manual

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 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
step, 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 rated current is above or equal to
400A and used in the complicated system in second environment.
A.6.1 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.
4. For the maximum motor cable length with 4 kHz switching frequency and without output filters, see EMC
compatibility and motor cable length
 In a domestic environment, this product may cause radio inference, in which case
supplementary mitigation measures may be required.
A.6.2 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:
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.
4. For the maximum motor cable length with 4 kHz switching frequency and without output filters, see EMC
compatibility and motor cable length
 A drive of category C3 is not intended to be used on a low-voltage public network
which supplies domestic premises. Radio frequency interference is expected if the
drive is used on such a network.
