EMC-compliant wiring

In terms of electromagnetic compatibility (EMC), the servo amplifier meets the requirements
of the following standards and laws:
}
The EMC Directive 2014/30/EU
} The Low Voltage Directive 2014/35/EU.
}
The EMC product standard EN 61800-3, which contains limit values and test methods
for noise emission and immunity for adjustable speed electrical power drive systems
(PDS):
–
–
Measures for ensuring the wiring is EMC-compliant are:
}

Earthing

}
Shielding
}
Filter
}
Chokes
6.5.1 Earthing
Earthing measures are a prerequisite for the effective use of additional EMC measures
such as shielding or filters:
}
All earthing points should be fed directly to the central earth bar (equipotential bonding
bar).
}
The connections must be low impedance and must be good conductors.
}
Connections should be kept as short as possible.
}
Connections to the earth bar should always be in star form.
}
Connections should be protected from corrosion.
} Flexible earthing straps should be used on moving earth parts (e.g. machine parts,
gates). Ensure these earthing straps are as short and wide as possible.
} Unused wires in a cable should be earthed at both ends.
