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.
