Electrostatic sensitive devices
ESD protective measures
NOTICE
Electrostatic discharge
Electronic modules contain components that can be destroyed by electrostatic discharge.
These modules can be easily destroyed by improper handling.
To protect your equipment against damage, follow the instructions given below.
● Never touch electronic modules unless absolutely necessary in the course of maintenance
and repair procedures.
● If the modules have to be touched, the body of the person concerned must be
electrostatically discharged immediately beforehand and be grounded.
● Electronic modules should not be brought into contact with electrically insulating materials
such as plastic film, plastic parts, insulating table supports or 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, e.g. metallized plastic or metal containers, conductive foam material or
domestic aluminum foil.
The necessary ESD protective measures for electrostatic sensitive devices are illustrated once
