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.
• Comply with the EMC information provided by the manufacturer of the converter. This is how
you prevent the limit values stipulated by IEC/EN 61000-6-2 .... IEC/EN 61000-6-4 for the
drive system (consisting of the machine and converter) from being exceeded.
• You must put appropriate EMC measures in place.
2.10 Thermal hazard
CAUTION
Machine overheating
The surface temperature of the machine can exceed 100° C. Non-observance of the following
notes can lead to minor injury or material damage.
• Do not touch any hot surfaces.
• Make sure that temperature-sensitive components (electric cables, electronic components)
do not come into contact with hot surfaces.
• Make sure that the machine does not overheat as this can destroy the windings/bearings
and the permanent magnets may become demagnetized.
• Only operate the motors in conjunction with e󹪜ective temperature monitoring.
2.11 Information about electromagnetic 󹪝elds
CAUTION
High magnetic 󹪞ux densities through permanent magnets
In order to avoid injury and material damage, note that the rotors of the synchronous machines
contain permanent magnets with high magnetic 󹪞ux densities and strong attraction forces to
ferromagnetic bodies.
• Make sure that persons with cardiac pacemakers do not come close to a disassembled rotor.
• Note that data stored on electronic data carriers can be destroyed.

WARNING
Electromagnetic 󹪝elds
Electromagnetic 󹪝elds are generated during operation of electrical power engineering
equipment, such as transformers, motors, etc.
Electromagnetic 󹪝elds can interfere with electronic devices, which could cause them to
malfunction. Cardiac pacemakers can be a󹪜ected, for example, which could cause serious
damage to health or even result in death. Steps must be taken, therefore, to ensure that
persons with heart pacemakers cannot enter these areas.
The plant operating company is responsible for taking appropriate measures (labels and hazard
warnings) to adequately protect operating personnel and others against any possible risk.
• Observe the relevant nationally applicable health and safety regulations. In Germany,
"electromagnetic 󹪝elds" are subject to regulations BGV B11 and BGR B11 stipulated by the
German statutory industrial accident insurance institution.
• Display adequate hazard warning notices.
• Place barriers around hazardous areas.
• Take appropriate measures (e.g. shields) to reduce electromagnetic 󹪝elds at their source.
2.12 Special designs and construction versions
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 Service Center.
