Charge
Every person without a conductive connection to the electrical potential of his/her
surroundings can be electrostatically charged.
The material with which an electrostatically-charged 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.
①
Synthetic materials
②
Wool
③
Antistatic materials such as wood or concrete
NOTICE
Grounding measures
There is no equipotential bonding without grounding. An electrostatic charge is not
discharged and may damage the ESD.
Protect yourself against discharge of static electricity. When working with electrostatic
sensitive devices, make sure that the person and the workplace are properly grounded.
