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 components, make sure that personnel, workplaces, and packaging are
well earthed.
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 must only be taken on boards when the measuring instrument 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 housing).
Safety information
Commissioning must not start until you have ensured that the machine, in which the
components described here are installed, complies with the Machinery Directive 98/37/EC.
Only appropriately qualified personnel may mount/install, commission and service the
SINAMICS S units.
The personnel must take into account the information provided in the technical customer
documentation for the product, and be familiar with and observe the specified danger and
warning notices.
Operational electrical equipment and motors have parts and components which are at
hazardous voltage levels, that if touched, can result in severe bodily injury or death.
All work on the electrical system must be carried out when the system has been
disconnected from the power supply.
