Operating Instructions, 03/2018, A5E41926185A
● Electronic modules should not be brought into contact with electrically insulating
materials, such as:
–
Plastic film
– Plastic parts
– Insulating table supports
– Clothing made of synthetic fibers
● Always place electrostatic sensitive devices on conductive bases.
● 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 necessary ESD protective measures for electrostatic sensitive devices are illustrated
once again in the following drawings:
a = conductive floor sur-
face
b = ESD table c = ESD shoes
d = ESD overall e = ESD wristband f = cabinet ground connection
Risk of explosion due to electrostatic discharge
Electrostatic discharge poses a potential ignition source. Dangerous electrostatic charges
can occur, for example as a result of mechanical friction, flowing air that contains particles -
or persons that are not appropriately grounded, e.g. when carrying out maintenance or
cleaning work.
In an explosive atmosphere, there is a risk of an explosion. This can result in death, serious
injury or material damage.
● Avoid carrying out work specified above on non-metallic parts, e.g. foam rubber for noise
dampeners/attenuators.
● Please comply with ESD protective measures.
