Technical data140Second environment (drive of category C3)The drive complies with the standard with the following provisions:1. The drive is equipped with EMC filter +E200. The filter is suitable for TN (earthed) and IT(unearthed) networks.2. The motor and control cables are selected as specified in the drive manuals.3. The drive is installed according to the instructions given in the drive manuals.4. Maximum cable length is 100 metres (328 ft).WARNING! A drive of category C3 is not intended to be used on a low-voltage public network whichsupplies domestic premises. Radio frequency interference is expected if the drive is used on such anetwork.Second environment (drive of category C4)If the provisions under Second environment (drive of category C3) cannot be met, e.g. the drive cannotbe equipped with EMC filter +E200 when installed in an IT (unearthed) network, the requirements of theEMC Directive can be met as follows:1. It is ensured that no excessive emission is propagated to neighbouring low-voltage networks. Insome cases, the natural suppression in transformers and cables is sufficient. If in doubt, the supplytransformer with static screening between the primary and secondary windings can be used.2. An EMC plan for preventing disturbances is drawn up for the installation. A template is availablefrom the local ABB representative.3. The motor and control cables are selected as specified in the Hardware Manual.4. The drive is installed according to the instructions given in the Hardware Manual.WARNING! A drive of category C4 is not intended to be used on a low-voltage public network whichsupplies domestic premises. Radio frequency interference is expected if the drive is used on such anetwork.Machinery DirectiveThe drive complies with the European Union Machinery Directive (98/37/EC) requirements for anequipment intended to be incorporated into machinery.Low voltageEquipmentLow voltageEquipmentEquipment(victim)Supply transformerMedium voltage networkStatic screenPoint of measurementDriveNeighbouring network
