ESD Precautions

When installing plug-in modules, take the following precautions to prevent ESD
(electrostatic discharge) from damaging the internal components of the
PathBuilder S330/310:
Always wear a properly-grounded anti-static wrist strap.
Transport static-sensitive components in anti-static packaging.
Keep static-sensitive components in their anti-static packaging until you are
ready to install them.
Just before removing components from their anti-static packaging, discharge
static electricity from your body by touching an unpainted metal surface.
When you remove modules from the shelf, place them printed circuit side
down on a nonconducting, static-free, flat surface.
