2.9 Interference voltages when operating the converter
2.7
Electromagnetic compatibility
This machine is designed in accordance with IEC/EN 60034 and when used as prescribed it
satisfies the requirements of European Directive 2004/108/EC on Electromagnetic
Compatibility.
2.8
Interference immunity
The machine fulfills the requirements regarding interference immunity in accordance with IEC/
EN 61000‑6‑2.
For machines with integrated sensors (e.g. PTC thermistors), the manufacturer of the complete
system must ensure sufficient interference immunity by selecting suitable sensor signal leads
and evaluation units.
2.9
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.
In order to avoid exceeding the limit values set for the drive system (machine and converter)
in IEC/EN 61000-6-3, the EMC information provided by the converter manufacturer must be
observed. You must put appropriate EMC measures in place.
