always always always unplug the power...
220V going thru your arm isn't a good idea.
you can get grounding
straps for your arm from farnell...
AFAIR most sun hardware come with anti-static straps for your hands/arms..
don't know when a voltage spike can fry your boards...i lost a modem from
a voltage spike ...sniff sniff..still miss him ..
later
