Figure 1: ESD label
When you handle components fitted with ESDs, you must observe the following 
points under all circumstances:
You must always discharge yourself of static charges (e.g. by touching a 
grounded object) before working.
The equipment and tools you use must be free of static charges.
Remove the power plug from the power socket before inserting or removing 
boards containing ESDs.
Always hold boards with ESDs by their edges.
Never touch pins or conductors on boards fitted with ESDs.
Use a grounding cable designed for this purpose to connect yourself to the 
system unit as you install/deinstall the board.
Place all components on a static-safe base.
