Observe the following protective measures for modules and
components sensitive to electrostatic discharge (ESD):
• Personnel responsible for storage, transport, and handling
must have training in ESD protection.
• ESD-sensitive components must be stored and transported in
the prescribed protective packaging.
• ESD-sensitive components may generally only be handled at
special ESD workplaces.
• Personnel, working surfaces, as well as all equipment and
tools which may come into contact with ESD-sensitive
components must have the same potential (e.g. by groun­
ding).
• Wear an approved grounding bracelet. The grounding bracelet
must be connected with the working surface through a cable
with an integrated 1 megaohm resistor.
• ESD-sensitive components may by no means come into con­
tact with chargeable objects, including most plastic materials.
• When inserting or removing ESD in/from other devices, the de­
vice must be safely disconnected from the supply.
