CHARGED SECTION AND HIGH VOLTAGE GENERATING POINT
Ë 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.
1. AC Power Cord
2. AC Inlet with Filter
3. Power Switch (S1)
4. Fuse (In the SW POWER SUPPLY Module)
5. STB Transformer and Converter Transformer

Ë High Voltage Generating Point
The places where voltage is 100V or more except for the
charged places described above. If the places are touched,
there is a risk of electric shock.
