Fundamental safety instructions 1.1 General safety instructions NOTICE Device damage caused by incorrect voltage/insulation tests Incorrect voltage/insulation tests can damage the device. • Before carrying out a voltage/insulation check of the system/machine, disconnect the devices as all converters and motors have been subject to a high voltage test by the manufacturer, and therefore it is not necessary to perform an additional test within the system/machine.
Fundamental safety instructions 1.2 Safety instructions for electromagnetic fields (EMF) Safety instructions for electromagnetic fields (EMF) WARNING Danger to life from electromagnetic fields Electromagnetic fields (EMF) are generated by the operation of electrical power equipment such as transformers, converters or motors. People with pacemakers or implants are at a special risk in the immediate vicinity of these devices/systems.
Siemens recommends strongly that you regularly check for product updates. For the secure operation of Siemens products and solutions, it is necessary to take suitable preventive action (e.g. cell protection concept) and integrate each component into a holistic, state-of-the-art industrial security concept.
Fundamental safety instructions 1.5 Residual risks of power drive systems Residual risks of power drive systems The control and drive components of a drive system are approved for industrial and commercial use in industrial line supplies. Their use in public line supplies requires a different configuration and/or additional measures.
