2.5
Interference voltages when operating the converter
WARNING
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.
Observe the EMC instructions of the converter manufacturer in order to avoid exceeding
the limit values according to IEC/EN 61000-6-3 for drive systems comprising machine and
converter. You must put appropriate EMC measures in place.
2.6
Special designs and construction versions
Note
Before carry out any work on the machine, determine the machine version.
If there are any deviations or uncertainty, contact the manufacturer, specifying the type
designation and serial number (see the rating plate), or contact the Siemens Service Center.
