C
ompatibility. It is the ability of electrical/electronic
equipment to operate without problems within an electromagnetic environment.
Likewise, the equipment must not disturb or interfere with any other product or
system within its locality.
First 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.
Drive of category C2:
drive of rated voltage less than 1000 V and intended to be
installed and commissioned only by a professional when used in the first
environment.
Note:
A professional is a person or organization having necessary skills in installing
and/or commissioning power drive systems, including their EMC aspects.
Category C2 has the same EMC emission limits as the earlier class first environment
restricted distribution. EMC standard IEC/EN 61800-3 does not any more restrict the
distribution of the drive, but the using, installation and commissioning are defined.
Drive of category C3:
drive of rated voltage less than 1000 V, intended for use in the
second environment and not intended for use in the first environment.
Category C3 has the same EMC emission limits as the earlier class second
environment unrestricted distribution.
Compliance with the IEC/EN 61800-3 (2004)
The immunity performance of the drive complies with the demands of
IEC/EN 61800-3, category C2 (see page
306
for IEC/EN 61800-3 definitions). The
emission limits of IEC/EN 61800-3 are complied with the provisions described below.
First environment (drives of category C2)
