Basic Installation Notes

You are required to follow all safety precautions during start-up 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 the, "Achieving Low
Impedance Connections" section 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.
