B.2 Electrostatic Charging Of Persons - Siemens S5-135U/155U System Manual

B.2 Electrostatic Charging of Persons
Charging Every person with a non-conductive connection to the electrical potential of
its surroundings can be charged electrostatically.
Figure B-1 shows you the maximum values for electrostatic voltages which
can build up on a person coming into contact with the materials indicated in
the figure. These values are in conformity with the specifications of
IEC 801-2.
