Components which can be damaged by electrostatic discharge (ESDs, electro- static-sensitive devices)

may have the following label:

Figure 1: ESD label

When handling modules with ESDs, it is essential that you observe the following guidelines:

You must electrostatically discharge yourself (e.g. by touching a grounded

object) before handling modules with ESDs.

Any devices or tools that are used must be free of electrostatic charge.

Pull out the power plug before installing or uninstalling modules containing

electrostatic-sensitive components.

Touch modules containing electrostatic-sensitive components only at the edges.

Do not touch any connectors or conduction paths on a module containing electrostatic-sensitive

components.

While installing modules, wear a suitable grounding strap that connects you to the system unit.

Place all the components on a pad which is free of electrostatic charge.

For a detailed description of how to handle ESD-module components, see the relevant

European or international standards (EN 61340-5-1, ANSI/ESD S20.20).
