Electrostatically sensitive modules
Definition
All electronic modules are equipped with highly integrated modules or components. Because
of the technology used, these electronic components are very sensitive to overvoltages and
thus to discharge of static electricity.
The acronym ESD has become the established designation for such Electrostatically
Sensitive Devices. The ESD designation is used internationally to refer to electrostatically
sensitive devices.
Electrostatically sensitive devices are identified by this symbol:

CAUTION
Electrostatically sensitive devices can be irreparably damaged by voltages that are far
lower than anything a person can perceive. These voltages occur if you touch a component
or the electrical connection of a module without having previously discharged any static
from your body. Any damage that occurs to a module as a result of overvoltage is generally
not recognized immediately and only comes to light after the equipment has been operating
for some time.
