CAUTION
Components which can be destroyed by electrostatic discharge (ESD)
The board contains components which can be destroyed by electrostatic discharge. These components can
be easily destroyed if not carefully handled. If you have to handle electronic boards, please observe the
following:
♦ Electronic boards should only be touched when absolutely necessary.
♦ You must ensure that your own body has been discharged before you touch a board (the best way to do
this is to touch an earthed, conductive object such as a socket-outlet earth contact).
♦ Boards must not come into contact with highly insulating materials − e.g. plastic foils, insulated desktops,
articles of clothing made from man-made fibres.
♦ Boards may only be placed on surfaces which are conductive.
♦ When soldering, the soldering iron tip must be grounded.
♦ Boards and components should only be stored and transported in conductive packaging (e.g. metalized
plastic boxes, metal containers).
♦ If the packing material is not conductive, the boards must be wrapped in a conductive packaging material,
e.g. conductive foam rubber or household aluminium foil.
