14-3 ComplianceAC10 InverterDefinitionsCategory C1PDS (Power Drive System) of rated voltage less than 1000V, intended for use in the first environmentCategory C2PDS (Power Drive System) of rated voltage less than 1000V, which is neither a plug in device nor amovable device and, when used in the first environment, is intended to be installed and commissionedonly by a professional.Note: A professional is a person or an organisation having necessary skills in installing and/or commissioning power drivesystems, including their EMC aspects.Category C3PDS (Power Drive System) of rated voltage less than 1000V, intended for use in the secondenvironment and not intended for use in the first environment.Category C4PDS (Power Drive System) of rated voltage equal to or above 1000V, or rated current equal to or above400A, or intended for use in complex systems in the second environment.First EnvironmentEnvironment that include domestic premises, it also includes establishments directly connected withouttransformers to a low-voltage power supply network which supplies buildings used for domesticpurposes.Note: Houses, apartments, commercial premises or offices in a residential building are examples of firstenvironment locations.Second EnvironmentEnvironment that includes all establishments other than those directly connected to a low -voltage powersupply network which supplies buildings used for domestic purposes.Note: Industrial areas, technical areas of any building fed from a dedicated transformer are examples ofsecond environment locations.14.3 EMC Standards ComparisonThe standards are concerned with two types of emissionRadiated Those in the band 30MHZ – 1000MHz which radiate into the environmentConducted Those in the band 150kHz – 30MHz which are injected into the supply.14.3.1 RadiatedThe standards have common roots (CISPR 11 & CISPR14) so there is some commonality in the testlevels applied in different environments.Relationship Between StandardsStandardsLimits*Product Specific GenericEN 61800-3 EN61000-6-3 EN61000-6-4Category C1 Equivalent Not applicable 30 – 230MHZ 30dB(μV/m)230 - 1000MHz 37dB(μV/m)Category C2 Not applicable Equivalent 30 – 230MHZ 40dB(μV/m)230 - 1000MHz 47dB(μV/m)Category C3 These limits have no relationships withthe generic standards.30 – 230MHZ 50dB(μV/m)230 - 1000MHz 60dB(μV/m)*Adjusted for 10mwww.comoso.com
