Issue Number: 5
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.
Key: (shown in decreasing order of permitted emission level):
E2R EN 61800-3:2004+A1:2012 second environment, restricted

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
