Avoid undefined states!
Select and install connection lines so that capacitive and inductive inter-
ferences do not have adverse effects on the system.
Protect the device against improper and unintended use.
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.
Components damaged by electrostatic discharge may produce temporary
faults in case of temperature changes, vibrations or load changes.
Only with a consistent use of protective devices and a responsible compliance
of the instructions for use can you avoid malfunctions or failures of the elec-
trostatically sensitive equipment.
Shipping For shipping electrostatically sensitive equipment, use always the original
packaging.
Measurements Observe the following notes for measurements on electrostatically sensitive
equipment:
