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.

Interference to electronic devices caused by electrical power equipment
Electrical power equipment generate electric fields during operation. Potentially lethal
malfunctions can occur in medical implants, e.g. pacemakers, in the vicinity of electrical power
equipment. Data may be lost on magnetic or electronic data carriers.
● It is forbidden for people with pacemakers to enter the vicinity of the machine.
● Protect the personnel working in the plant by taking appropriate measures, such as
