4PDP-503CMX, PDP-503MXE, PDA-50027 Charged SectionThe places where the commercial AC power is used withoutpassing 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 theGND of the charged section and the GND of the non-chargedsection while connecting the set directly to the commercial ACpower supply. Therefore, be sure to connect the set via an insulatedtransformer and supply the current.1. AC Power Cord2. AC Inlet with Filter3. Power Switch (S1)4. Fuse (In the SW POWER SUPPLY Module)5.
