6 electrical Installation6.1 General informationThis chapter contains the information which must be observed when selecting the wires,the protective measures and wiring in the control cabinet.ATTENTION Current laws and local regulations must always be observed whenplanning and carrying out the installation. KEB assumes no liability forinstallations where laws, local and / or other regulations have not beencomplied with. If the recommendations given by KEB are not observed,you might experience problems when using the drive converter whichare not covered by the warranty.The specified Cable cross-sections are recommendations for dimensioning and serveas guide values for multicore copper cables. They are valid for a maximum ambienttemperature of 40 °C and for open installation. This must be considered accordingly incase of deviating ambient conditions and local regulations.6.1.1 Wiring• Lay noise-affected or noise sensitive cables as far apart from each other as possible(minimum 200 mm).• If the distance cannot be maintained, additional shielding measures must be pro-vided.• Cables must be routed as closely as possible to earthed housing parts, mountingplates or cabinet frames. This reduces noise emissions and noise injections.• Crossings of cables of different classes are to be tolerated, parallel laying shouldbe avoided.• If another laying is not possible, cross the cables at right angles, especially if thesignals are sensitive and interference emitted.• Cores of signal and data lines that are not used must be earthed at both ends.• Avoid long lines and interference sources in order to prevent additional couplingpoints.• Ground unused lines on one side in the control cabinet.• Establish ground connections with the largest possible cross-section to other controlcabinets, system components and decentralized devices.• Avoid larger conductor loops.63eLecTrIcAL INSTALLATION
