Table 2-35 Size 11E emission compliance
Key (shown in decreasing order of permitted emission level):
E2R EN 61800-3:2004 second environment, restricted distribution (Additional measures may be required to prevent interference)
E2U EN 61800-3:2004 second environment, unrestricted distribution
I Industrial generic standard EN 61000-6-4:2007
EN 61800-3:2004 first environment restricted distribution (The following caution is required by EN 61800-3:2004)
R Residential generic standard EN 61000-6-3:2007
EN 61800-3:2004 first environment unrestricted distribution
EN 61800-3:2004 defines the following:
• The first environment is one that includes residential premises. It also includes establishments directly connected without intermediate
transformers to a low-voltage power supply network which supplies buildings used for residential purposes.
• The second environment is one that includes all establishments other than those directly connected to a low-voltage power supply network which
supplies buildings used for residential purposes.
• Restricted distribution is defined as a mode of sales distribution in which the manufacturer restricts the supply of equipment to suppliers,
customers or users who separately or jointly have technical competence in the EMC requirements of the application of drives.
IEC 61800-3:2004 and EN 61800-3:2004
The 2004 revision of the standard uses different terminology to align the requirements of the standard better with the EC EMC Directive.
Power drive systems are categorized C1 to C4:
Note that category 4 is more restrictive than E2R, since the rated current of the PDS must exceed 400 A or the supply voltage exceed 1000 V, for the
complete PDS.
