2.1.6 Electrostatic sensitive devices
Material damage due to electrostatic discharge
Electronic modules contain components that can be destroyed by electrostatic discharge. These
components can be damaged or destroyed if they are not handled correctly. To protect
equipment against damage, follow the instructions given below.
• Only touch electronic modules if you absolutely have to work on them.
• The body of the person concerned must have been electrostatically discharged and
grounded immediately before any electronic modules are touched.
• Electronic modules should not be brought into contact with electrically insulating materials,
such as:
– Plastic lm
– Plastic parts
– Insulating table supports
– Clothing made of synthetic bers
• Always place the modules on conductive and grounded surfaces.
• Always pack, store and transport electronic modules or components in conductive
packaging, such as:
– Metallized plastic or metal containers
– Conductive foam material
– Domestic aluminum foil
The ESD protective measures required for components that can be destroyed due to
electrostatic discharge are shown in the following drawings:

Risk of explosion due to electrostatic discharge
Electrostatic discharge poses a potential ignition source. Dangerous electrostatic charging can
occur, for example as a result of mechanical friction, owing air that contains particles,
processes that generate signicant levels of charge – or persons that are not appropriately
grounded, e.g. when carrying out maintenance or cleaning work.
