Electrocution danger!
Electrocution danger exists when live components are touched.
Electrical components which are switched on can carry out
uncontrolled movements and lead to serious injury or death.
Before beginning work, switch off the electrical power supply and
secure against restarting.
Electrocution danger from stored charges!
In electronic components, electrical charges can be stored which
are present even after switching off and disconnecting from the
power supply. Any contact with these components can lead to seri-
ous injury or death.
Before working on the components mentioned, disconnect them
completely from the power supply. Allow 10 min to pass in order
to be sure that the internal capacitors are completely discharged
