Hello Rachid Ammar,

Having worked on serious industrial grade electronics both my adult careers.. I know these things come with serious technical service guides, bulletins & alerts...

Modern plug-n-play electronics is great fun... but
industrial grade equipment is an entirely different
kind of situation... and TYPICALLY amazingly...
Astoundingly EXPENSIVE.

If you know what ESD means... (you know better)
get the manufacture's guidelines...

ELSE
Put your hands in your pockets and back away...

I see there are videos on "YouTube".
If you are NOT HIGHLY SKILLED... don't even think about it.
