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. 1. SW POWER SUPPLY Module ...................................... (215V) 2. X DRIVE Assy ............................................... (�280V to 215V) 3. Y DRIVE Assy ................................................................(345V) 4. SCAN (A) Assy .............................................................. (345V) 5. SCAN (B) Assy .............................................................. (345V) 6. X CONNECTOR (A) Assy ............................ (�280V to 215V) 7. X CONNECTOR (B) Assy ............................ (�280V to 215V)

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.
