1.1.3 ESD instructions
All electronic modules and electronic assemblies feature electrostatic
sensitive devices.
The following measures must be taken in order to protect these
electrostatic sensitive devices:
Ensure that the assemblies and modules are appropriately identified.
Before you touch and measure the ESDs, put on an electrostatic
protection system (wrist band with earthing module).
Avoid touching ESDs with chargeable plastics (film, etc.).
When taking hold of assemblies, modules and printed circuit boards,
try not to touch the printed conductors or connections.
Keep ESDs away from monitors and television sets.
Only use conductive materials or the original packaging for
transportation.
1.1.4 Electrostatic protection system
The electrostatic voltage of the body is discharged via the wrist band
and the earthing module.
For reasons of safety this does not occur directly, but via a combina-
tion of resistors.
The earthing or protective conductor connection must not be
damaged!
