Figure 1: ESD label
When you handle components fitted with ESDs, you must always observe the
following points:
●
Switch off the system and remove the power plugs from the power outlets
before installing or removing components with ESDs.
●
The circuit boards and soldered parts of internal options are exposed and
can be damaged by static electricity. To ensure reliable protection, you must
wear an earthing band on your wrist when working with this type of module
and connect it to an unpainted, conducting metal part of the system.
●
Any devices or tools that are used must be free of electrostatic charge.
●
Wear a suitable grounding cable that connects you to the external chassis
of the system unit.
●
Always hold components with ESDs at the edges or at the points marked
green (touch points).
●
Do not touch any connectors or conduction paths on an ESD.
●
Place all the components on a pad which is free of electrostatic charge.
