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
• Modules must not come into contact with highly insulating materials (such as plastic
• Modules must only be set down on conductive surfaces.
• Modules and components should only be stored and transported in conductive
• If the packaging is not conductive, the modules must be wrapped with a conductive
