An electric shock can be fatal. Before opening up the power source, switch it
off, unplug it from the mains and put up a clearly legible and easy-to-understand
warning sign to stop anybody inadvertently switching the machine back on
again. If necessary, discharge the electrolytic capacitors. The fixing-screws of
the housing are used as an appropriate earth connection. Do not use other
screws without appropriate earth connection.
