2.4 Notes on electrostatically sensitive equipment
NOTICE
Electrostatic sensitive product
The assemblies might get damaged.
 Ensure sufficient grounding of persons and working material!
Handling
Murrelektronik assemblies include highly integrated MOS com-
ponents. These components are extremely sensitive to over-
voltage occurring, for example, due to electrostatic discharge.
Assemblies at risk are marked with the adjacent symbol.
The symbol is affixed to assemblies, sub-racks or packaging
and indicates electrostatically sensitive equipment. These as-
semblies may become irreparably damaged by voltage and energy levels
which are far below the perception levels of human beings.
If a person who is not electrostatically discharged handles electrostatically
sensitive equipment, voltages may be produced. They may damage compo-
nents, impair the functioning of assemblies or render assemblies inoperative.
Frequently, assemblies thus damaged cannot directly be recognized as faulty.
The fault may only show up after prolonged operation.
