Installation
Basic Installation Notes
You are required to follow all safety precautions during startup such as providing proper equipment grounding, correctly fused power, and an effective Emergency Stop circuit which can immediately remove power in the case of a malfunction. See the “Safety Considerations” section for more information.
Electromagnetic Compatibility (EMC)
Drives are designed to meet the requirements of EMC. Under extreme conditions a drive might cause or suffer from disturbances due to electromagnetic interaction with other equipment. It is the responsibility of the installer to ensure that the equipment or system into which the drive is incorporated complies with the relevant EMC legislation in the country of use.
The following instructions provide you with installation guidance designed to help you meet the requirements of the EMC Directive 89/336/EEC.
Adhering to the following guidelines will greatly improve the electromagnetic compatibility of your system; however, final responsibility for EMC compliance rests with the machine builder, and Control Techniques cannot guarantee your system will meet tested emission or immunity requirements.
If you need to meet EMC compliance requirements, EMI/RFI line filters must be used to control conducted and radiated emissions as well as improve conducted immunity.
Physical location of these filters is very important in achieving these benefits. The filter output wires should be kept as short as possible (12 inches is suggested) and routed away from the filter input wires. In addition:
•Choose an enclosure made of a conductive material such as steel, aluminum, or stainless steel.
•Devices mounted to the enclosure mounting plate, which depend on their mounting surfaces for grounding, must have the paint removed from their mounting surfaces and the mating area on the mounting plate to ensure a good ground. See “Achieving Low Impedance Connections” on page 4 for more information.
•If grounding is required for cable grommets, connectors, and/or conduit fittings at locations where cables are mounted through the enclosure wall, paint must be removed from the enclosure surface at the contact points.
•AC line filter input and output wires and cables should be shielded, and all shields must be grounded to the enclosure.
