Compliance with the EN 61800-3:2004

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 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 C3


The drive complies with the standard with the following provisions:
6. The motor and control cables are selected as specified in the hardware manual.
7. The drive is installed according to the instructions given in the hardware manual.
8. Maximum motor cable length is 100 meters.
WARNING! A drive of category C3 is not intended to be used on a low-voltage public
network which supplies domestic premises. Radio frequency interference is expected if
the drive is used on such a network.

Category C4


If the provisions under
be met as follows:
1. It is ensured that no excessive emission is propagated to neighbouring low-voltage
networks. In some cases, the natural suppression in transformers and cables is
Category C3 cannot be met, the requirements of the standard can
