Siemens SINAMICS S120 Combi Equipment Manual page 9

Electrical, magnetic and electromagnetic fields (EMF) that occur during operation can pose
a danger to persons who are present in the direct vicinity of the product - especially
persons with pacemakers, implants, or similar devices.
The relevant directives and standards must be observed by the machine/plant operators
and persons present in the vicinity of the product. These are, for example, EMF Directive
2004/40/EEC and standards EN 12198-1 to -3 applying to the European Economic Area
(EEA) and in Germany the accident prevention regulation BGV 11 and the associated rule
BGR 11 "Electromagnetic fields" from the German employer's liability accident insurance
association.
These state that a hazard analysis must drawn up for every workplace, from which
measures for reducing dangers and their impact on persons are derived and applied, and
exposure and danger zones are defined and observed.
The relevant safety notes in each chapter must be observed.
ESD information
Electrostatic sensitive devices (ESDs) are individual components, integrated circuits, or
boards that may be damaged by either electrostatic fields or electrostatic discharge.
Regulations for handling ESD components:
When handling electronic components, you must ensure that the person carrying out the
work, the work place, and packaging are properly grounded.
Personnel may only come into contact with electronic components, if
• They are grounded with an ESD wrist band, or
• They are in ESD areas with conductive flooring, ESD shoes or ESD grounding straps.
Electronic boards should only be touched if absolutely necessary. They must only be
handled on the front panel or, in the case of printed circuit boards, at the edge.
Electronic boards must not come into contact with plastics or items of clothing containing
synthetic fibers.
Boards must only be placed on conductive surfaces (work surfaces with ESD surface,
conductive ESD foam, ESD packing bag, ESD transport container).
Do not place boards near display units, monitors, or television sets (minimum distance from
screen: 10 cm).
Measurements may only be taken on boards when the measuring device is grounded (via
protective conductors, for example) or the measuring probe is briefly discharged before
measurements are taken with an isolated measuring device (for example, touching a bare
metal enclosure).
