CAUTION
Electrostatically sensitive devices
The converter contains electrostatically sensitive devices. These can easily be destroyed if they are not
handled correctly. If, however, it is absolutely essential for you to work on electronic modules, please pay
careful attention to the following instructions:
• Electronic modules (PCBs) should not be touched unless work has to be carried out on them.
• Before touching a PCB, the person carrying out the work must be electrostatically discharged. The
simplest way of doing this is to touch an electrically conductive earthed object, e.g. socket outlet earth
contact.
• PCBs must not be allowed to come into contact with electrically insulating materials − plastic foil,
insulating table tops or clothing made of synthetic fibres
• PCBs may only be set down or stored on electrically conducting surfaces.
• When carrying out soldering jobs on PCBs, make sure that the soldering tip has been earthed.
• PCBs and electronic components should generally be packed in electrically conducting containers (such
as metallized-plastic boxes or metal cans) before being stored or shipped.
• If the use of non-conducting packing containers cannot be avoided, PCBs must be wrapped in a
conducting material before being put in them. Examples of such materials include electrically conducting
foam rubber or household aluminium foil.
For easy reference, the protective measures necessary when dealing with sensitive electronic components
are illustrated in the sketches below.
