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 must put appropriate EMC measures in place.

Electromagnetic fields when operating electrical power engineering
installations
Electrical power equipment generate electromagnetic 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.
● Protect the personnel working in the plant by taking appropriate measures, such as erecting
● Observe the nationally applicable health and safety regulations.
● It is forbidden for people with pacemakers to be close to the machine.
● Do not carry any magnetic or electronic data media.
