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 himself be electro-
statically 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 fibers
−
•
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.
