Electrostatic Sensitive Devices (ESD)
The device contains components which can be destroyed by electrostatic
discharge. These components can be easily destroyed if not carefully handled.
Before opening the cabinet/enclosure in which the device is located, you must
electrically discharge your body and apply the appropriate ESDS protective
measures. The cabinet/enclosure should be appropriately labeled.
If you have to handle electronic boards, please observe the following:
• Electronic boards should only be touched when absolutely necessary.
• The human body must be electrically discharged before touching an electronic
board.
• Boards must not come into contact with highly insulating materials - e.g. plastic
parts, insulated desktops, articles of clothing manufactured from man-made
fibers.
• Boards must only be placed on conductive surfaces.
• Boards and components should only be stored and transported in conductive
packaging (e.g. metalized plastic boxes or metal containers).
• If the packing material is not conductive, the boards must be wrapped with a
conductive packaging material, e.g. conductive foam rubber or household
aluminium foil.
The necessary ESD protective measures are clearly shown again in the following
