2.3 ESD Guidelines
NOTICE
Electrostatic discharge
ESD devices can be destroyed by voltages well below the threshold of human perception. These
static voltages develop when you touch a component or electrical connection of a device
without having drained the static charges present on your body. The damage caused to a device
by overvoltage is usually not immediately evident and is only noticed after an extended period
of operation.
Electrostatic charging
Anyone who is not connected to the electrical potential of their surroundings can be
electrostatically charged.
The diagram below shows the maximum electrostatic voltage which may build up on a person
coming into contact with the materials specified in the diagram. These values correspond to
IEC 801-2 specifications.
