1.3 CHARGED SECTION AND HIGH VOLTAGE GENERATING POINT
7 Charged Section
The places where the commercial AC power is used
without passing through the power supply transformer.
If the places are touched, there is a risk of electric shock.
In addition, the measuring equipment can be damaged if it
is connected to the GND of the charged section and the
GND of the non-charged section while connecting the set
directly to the commercial AC power supply. Therefore,
be sure to connect the set via an insulated transformer and
supply the current.
