1.2 ESD-sensitive components
CAUTION
The electronic boards contain electrostatic sensitive devices. These can be easily
destroyed if not handled properly. If you have to work with electronic modules, please note:
• You should only touch electronic modules if absolutely necessary.
• If you do have to touch modules, your body must be electrically discharged first.
• Boards 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.
• Boards and components should only be stored and transported in conductive packaging
(such as metalized plastic boxes or metal containers).
• If the packaging material is not conductive, the modules must be wrapped with a
conductive packaging material (such as conductive foam rubber or household aluminum
foil).
The necessary ESD protection measures are elucidated once again in the following
