EMC stands for Electromagnetic Compatibility. 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 organisation 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.
