EMC compliance (IEC/EN 61800-3:2004 + A2012)
￭ Definitions
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 supplying domestic
premises.
Drive of category C2: drive of rated voltage less than 1000 V and intended to be installed
and started up 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 starting up power
drive systems, including their EMC aspects.
Drive of category C3: drive of rated voltage less than 1000 V and intended for use in the
second environment and not intended for use in the first environment.
Drive of category C4: drive of rated voltage equal to or above 1000 V, or rated current equal
to or above 400 A, or intended for use in complex systems in the second environment.
￭ Category C2
The drive complies with the C2 category with these provisions:

See the supply module hardware manual.
2. The drive is connected to a TN (grounded) network.
3. The motor and control cables are selected, and routed according to the electrical planning
guidelines of the drive. The EMC recommendations are obeyed.
4. The drive is installed according to its installation instructions. The EMC recommendations
are obeyed.
5. Motor cable length (for any inverter unit) does not exceed 100 meters (328 ft).
WARNING!
The drive may cause radio interference. The installer is required to take measures
to prevent interference, in addition to the requirements for CE compliance listed
above, if necessary.
