CAUTION
Electrostatically Sensitive Devices (ESDs)
The equipment contains electrostatically sensitive devices. These components may be destroyed very easily
by improper handling. Please observe the following notes if you nevertheless have to work with electronic
modules:
♦ Electronic modules should only be touched if absolutely necessary to carry out work on them.
♦ If modules nevertheless have to be touched, you must discharge your own body directly beforehand (this
is best done by touching an earthed conductive object such as the PE contact of a socket).
♦ Modules must not come into contact with highly insulating materials − e.g. plastic films, insulating desktops
or synthetic fibber clothing items.
♦ Modules must only be placed on conductive surfaces.
♦ When soldering modules, the tip of the soldering iron must be earthed.
♦ Modules and components must only be stored or dispatched in conductive packaging (e.g. metallized
plastic boxes or metal tins).
♦ If packagings are not conductive, modules must be placed in a conductive envelopment prior to
packaging. In this case, use can be made of conductive foam rubber or domestic aluminum foil, for
example.
