• Before touching an electronics module, you must electrically
discharge your body. This can be simply done by touching a
conductive, grounded object immediately beforehand (e. g. bare metal
cabinet parts, water pipe etc.)
• Modules may not come into contact with highly insulating materials
which can be statically charged. This includes plastic foils, insulating
desktops, clothing manufactured out of man-made fibers.
• Modules may only be placed down on conductive surfaces (desktop
with ESD surface, conductive ESD foam rubber, ESD packing bags,
ESD transport containers, cardboard- or paper surfaces).
• Modules may not be brought close to data terminals, monitors or
television sets.
• It only permissible to make measurements at the modules, if
− the measuring unit is grounded (e. g. via protective conductor) or
− before making measurements with an electrically-isolated
measuring device, the probe is briefly discharged (for example by
touching a bare metal control housing).
When carrying-out soldering work on modules, ESD soldering irons must
be used or at least the soldering iron tip grounded.
