Interference voltages when operating the converter
Interference voltages when operating the converter
When a converter is in operation, the emitted interference varies in strength depending on the
converter (manufacturer, type, interference suppression measures undertaken). On machines
with integrated sensors (e.g. PTC thermistors), interference voltages caused by the converter
may occur on the sensor lead. This can cause faults which can result in eventual or immediate
death, serious injury or material damage.
• Comply with the EMC information provided by the manufacturer of the converter. This is how
you prevent the limit values stipulated by IEC/EN 61000-6-2 .... IEC/EN 61000-6-4 for the
drive system (consisting of the machine and converter) from being exceeded.
• You must put appropriate EMC measures in place.
2.10
Thermal hazard
Machine overheating
The surface temperature of the machine can exceed 100° C. Non-observance of the following
notes can lead to minor injury or material damage.
• Do not touch any hot surfaces.
• Make sure that temperature-sensitive components (electric cables, electronic components)
• Make sure that the machine does not overheat as this can destroy the windings/bearings
• Only operate the motors in conjunction with effective temperature monitoring.
2.11
Information about electromagnetic fields
High magnetic flux densities through permanent magnets
In order to avoid injury and material damage, note that the rotors of the synchronous machines
contain permanent magnets with high magnetic flux densities and strong attraction forces to
ferromagnetic bodies.
• Make sure that persons with cardiac pacemakers do not come close to a disassembled rotor.
• Note that data stored on electronic data carriers can be destroyed.

CAUTION
do not come into contact with hot surfaces.
and the permanent magnets may become demagnetized.
