Electrostatic sensitive devices can be labeled with an appropriate symbol.
CAUTION
Damage to ESD from touch
Electrostatic sensitive devices, ESD, can be destroyed by voltages which are far below the
human perception limit. If you touch a component or electrical connections of a module
without discharging any electrostatic energy, these voltages may arise.
The damage to a module by an overvoltage can often not be immediately detected and only
becomes evident after an extended period of operation. The consequences are incalculable
and range from unforeseeable malfunctions to a total failure of the machine or plant.
Avoid touching components directly. Make sure that persons, the workstation and the
packaging are properly grounded.
Charge
Every person without a conductive connection to the electrical potential of his/her
surroundings can be electrostatically charged.
The material with which this person comes into contact is of particular significance. The
figure shows the maximum electrostatic voltages with which a person is charged, depending
on humidity and material. These values conform to the specifications of IEC 61000-4-2.
