1.2 Electrostatic sensitive devices (ESD)
CAUTION
The Cabinet Modules contain electrostatic sensitive devices. These components can be
easily destroyed if not handled properly. Observe the following notes if you nevertheless
have to work with electronic modules:
•You should only touch electronic modules if absolutely necessary.
•If you do have to touch modules, your body must be electrically discharged first. For this
purpose, you are advised to wear a grounded ESD wristband.
•Modules must not come into contact with highly insulating materials (such as plastic
parts, insulated desktops, articles of clothing manufactured from man-made fibers).
•Modules must only be set down on conductive surfaces.
•Modules and components should only be stored and transported in conductive
packaging (such as metalized plastic boxes or metal containers).
•If the packaging is not conductive, the modules must be wrapped with a conductive
packaging material (such as conductive foam rubber or household aluminum foil), prior
to placing them in the packaging.

WARNING
Electromagnetic fields "electro smog"
Electromagnetic fields are generated by the operation of electrical power engineering
installations such as transformers, converters or motors.
Electromagnetic fields can interfere with electronic devices, which could cause them to
malfunction. For example, the operation of pacemakers can be impaired, potentially leading
to damage to a person's health or even death. It is therefore forbidden for persons with
pacemakers to enter these areas.
The plant operator is responsible for taking appropriate measures (labels and hazard
warnings) to adequately protect operating personnel and others against any possible risk.
•Observe the relevant nationally applicable health and safety regulations. In Germany,
"electromagnetic fields" are subject to regulations BGV B11 and BGR B11 stipulated by
the German statutory industrial accident insurance institution.
•Display adequate hazard warning notices.
•Place barriers around hazardous areas.
•Take measures, e.g. using shields, to reduce electromagnetic fields at their source.
•Make sure that personnel are wearing the appropriate protective gear.
