6.5 EMC-compliant wiring 6500 EMC-compliant wiring 6- ][EMV_Allgemein
In terms of electromagnetic compatibility (EMC), the servo amplifier
meets the requirements of the following standards and laws:
 The EMC Directive 2004/108/EC
 The Low Voltage Directive 2006/95/EC
 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):
– Noise immunity: "Second environment" category (industrial envi-
ronment)
– Noise emission:
Category C2 (length of motor cable ≤ 10 m)
Category C3 (length of motor cable ≥ 10 m)
Measures for ensuring the wiring is EMC-compliant are:
 Earthing
 Shielding
 Filters
 Chokes

6.5.1 Earthing
Earthing 6- ][EMV_Erdung
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 (equi-
potential bonding bar).
 The connections must be low impedance and must be good conduc-
tors.
 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.
WARNING!
In a residential environment this product may cause high-fre-
quency noise, so that suppression measures may be required.
