5.4 EMC−compliant installation
EMC−compliant installation is a prerequisite for a safe and trouble−free operation of the
devices.
EMC interferences can
ƒ interrupt the CAN communication,
ƒ cause the drives and on−board converters to be switched off to protect the systems.
5.4.1 Equipotential bonding
Conditions for a working EMC concept:
ƒ Avoid current loops because they cause induced voltage differences.
ƒ Arrange the equipotential bonding in star shape and avoid earth loops.
ƒ Install equipotential bonding conductors in parallel to the supply and
communication cables.
– A equipotential bonding conductor in the motor cable extends the current
compensation by high−frequency currents and avoids an overload of the cable
shield.
