Siemens SINAMICS SM120 - Figure 2-1 ESD Protective Measures

● Bring components into contact only with ESD-compliant materials, e.g. ESD tables, ESD
surfaces, ESD packaging.
● Only carry out measurements on the components if one of the following conditions is met:
– The measuring device is grounded with a protective conductor, for example.
– The measuring head of a floating measuring device has been discharged directly before
the measurement.
The necessary ESD protective measures for the entire working range for electrostatically
sensitive devices are illustrated once again in the following drawings.
Precise instructions for ESD protective measures are specified in the standard
DIN EN 61340‑5‑1.
