3 Installation3.1 Safety InstructionsSee chapter 2 Safety for general safety instructions.3.2 EMC-compliant InstallationTo obtain an EMC-compliant installation, follow theinstructions provided in the relevant frequency converteroperating instructions and design guide. Refer to thefieldbus master manual from the PLC supplier for furtherinstallation guidelines.3.3 Grounding• Ensure that all stations connected to the fieldbusnetwork are connected to the same groundpotential. When there are long distances betweenthe stations in a fieldbus network, connect theindividual station to the same ground potential.Install equalising cables between the systemcomponents.• Establish a grounding connection with low HFimpedance, for example by mounting thefrequency converter on a conductive back plate.• Keep the ground wire connections as short aspossible.• Establish electrical contact between the cablescreen and the frequency converter enclosure byusing metal cable glands or by using the clampsprovided on the equipment.• Use high-strand wire to reduce electricalinterference.3.4 Cable RoutingNOTICEEMC INTERFERENCEUse screened cables for motor and control wiring, andseparate cables for fieldbus communication, motorwiring, and brake resistor. Failure to isolate fieldbuscommunication from motor and brake resistor cables canresult in unintended behaviour or reduced performance.Minimum 200 mm (7.9 in) clearance between power,motor, and control cables is required. For power sizesabove 315 kW, it is recommended to increase theminimum distance to 500 mm (20 in).NOTICEWhen the fieldbus cable crosses a motor cable or a brakeresistor cable, ensure that the cables cross at an angle of90°.130BD866.10≥ 200mm211 Fieldbus cable2 90° crossingIllustration 3.1 Cable RoutingInstallation VLT® CANopen MCA 1056 Danfoss A/S © 05/2015 All rights reserved.
