Fundamental safety instructions
2.5 Residual risks of power drive systems
3. Hazardous shock voltages caused by, for example,
– Component failure
– Influence during electrostatic charging
– Induction of voltages in moving motors
– Operation and/or environmental conditions outside the specification
– Condensation/conductive contamination
– External influences/damage
4. Electrical, magnetic and electromagnetic fields generated in operation that can pose a
risk to people with a pacemaker, implants or metal replacement joints, etc., if they are too
close
5. Release of environmental pollutants or emissions as a result of improper operation of the
system and/or failure to dispose of components safely and correctly
Note
The components must be protected against conductive contamination (e.g. by installing them
in a control cabinet with degree of protection IP54 according to IEC 60529 or NEMA 12).
Assuming that conductive contamination at the installation site can definitely be excluded, a
lower degree of cabinet protection may be permitted.
For more information about residual risks of the components in a drive system, see the
relevant sections in the technical user documentation.
