■ Compliance with the EN 61800-3:2004DefinitionsEMC stands for Electromagnetic Compatibility. It is the ability of electrical/electronicequipment 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 suppliesbuildings used for domestic purposes.Second environment includes establishments connected to a network not supplying domesticpremises.Drive of category C3: drive of rated voltage less than 1000 V and intended for use in thesecond 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 equalto or above 400 A, or intended for use in complex systems in the second environment.Category C2The drive frames R6 to R9 comply with the standard with the following provisions:1. The motor and control cables are selected as specified in the hardware manual.2. The drive is installed according to the instructions given in the hardware manual.3. Maximum motor cable length is 150 meters.WARNING!The drive may cause radio interference if used in a residential or domesticenvironment. The user is required to take measures to prevent interference, inaddition to the requirements for CE compliance listed above, if necessary.Note:Do not install a drive equipped with EMC filter on IT (ungrounded) systems. The supplynetwork becomes connected to ground potential through the EMC filter capacitors whichmay cause danger or damage the unit.Category C3The drive complies with the standard with the following provisions:1. The motor and control cables are selected as specified in the hardware manual.2. The drive is installed according to the instructions given in the hardware manual.3. Maximum motor cable length is 100 meters.WARNING!A drive of category C3 is not intended to be used on a low-voltage public networkwhich supplies domestic premises. Radio frequency interference is expected ifthe drive is used on such a network.Category C4If the provisions under Category C3 cannot be met, the requirements of the standard canbe met as follows:1. It is ensured that no excessive emission is propagated to neighboring low-voltagenetworks. In some cases, the natural suppression in transformers and cables is sufficient.Technical data 219
