B.3  Basic measures for protection against discharge of static electricity 
Ensure sufficient grounding 
When working with electrostatic sensitive devices, make sure that the you, your workstation, 
and the packaging are properly grounded. This prevents the accumulation of static 
electricity. 
Avoid direct contact 
You should only touch ESD components if unavoidable (for example, during maintenance 
work). When you touch modules, make sure that you do not touch either the pins on the 
modules or the printed conductors. If you follow these instructions, electrostatic discharge 
cannot reach or damage sensitive components. 
If you have to take measurements on a module, make sure that you first discharge any static 
that may have accumulated in your body. To do this, touch a grounded metal object. Only 
use grounded measuring instruments.
