2.5 Dangerous voltage when the rotor rotates

2.5 Dangerous voltage when the rotor rotates
Dangerous voltage when the rotor rotates
There are dangerous voltages at the terminals while the machine rotor rotates and
immediately afterwards.
You must observe the following safety instructions to prevent death, injury or material
damage:
• Do not touch the terminals while the rotor is rotating and immediately afterwards.
• To discharge the winding, after the rotor comes to a standstill, connect the winding to
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
• Observe the nationally applicable health and safety regulations.
• Do not carry any magnetic or electronic data media.

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.
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.
