1.2 ESD guidelines
1.2.1 What is ESD?
Almost all of the SIMADYN D modules have highly-integrated devices.
These devices are, from their very nature, extremely sensitive to
overvoltage conditions, and therefore also to electrostatic discharge.
The abbreviation stands for electrostatic discharge

ORIGINAL PACKING
Modules, which use these devices have the following warning label on
the component side:
Electrostatic sensitive devices can be destroyed by voltage- and energy
level which lie far below the perception levels of human beings.
Voltages such as these occur when personnel touch a component or a
module without having first being previously electrostatically discharged.
Components, which have been subject to such overvoltage conditions,
can generally not be immediately identified as being faulty, as this is only
manifested after a somewhat longer operating time.
1.2.2 Handling ESD modules
• As a general rule, electronic modules should only be touched if this is
absolutely necessary.
• Components may only be touched if the person
− is continuously grounded through an ESD bracelet, or
− is wearing ESD shoes or ESD shoe grounding strips.
