Electrostatic Discharge to Persons
Charge
Any person with a non-conductive connection to the electrical potential of his or her
surroundings may be exposed to electrostatic charge.
The following figure shows the maximum electrostatic voltage which can build up on a
person coming into contact with the materials indicated. These values correspond with
specifications to IEC 801–2.

Basic protective measures against discharge of static electricity
Make sure the grounding is good
When working with electrostatically sensitive devices, make sure that the person, the
workstation and the packaging are properly grounded, which helps you avoid static charge.
You should only touch ESD components if this is unavoidable (for example, during
maintenance work). When you touch modules, make sure that you do not touch either the
pins on the modules or the printed conductors. This prevents any discharge of static
electricity to sensitive component and thus avoids damage.
Discharge your body before beginning work on a module. To do so, touch a grounded
metallic object. Use only grounded measuring and test equipment.
