other than the 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.

: Part is Charged Section.
Charged Section
The places where voltage is 100 V or more except for the charged
places described above. If the places are touched, there is a risk of
electric shock.
The VSUS voltage remains for several minutes after the power to
the unit is turned off. These places must not be touched until
about 10 minutes after the power is turned off, or it is confirmed
with a tester that there is no residual VSUS voltage.
If the procedures described in “10.3 POWER ON/OFF
FUNCTION FOR THE LARGE-SIGNAL SYSTEM” are
performed before the power is turned off, the voltage will be
discharged in about 30 seconds.
