Warnings Provided in the Instruction Manual
Notes that have been described to the manual and their description places are shown
as follows.
Use in humid and dusty place
 Do not use the system near a sink, a humidifier, or any place near water, in a humid
basement room, or a dusty place or a place subject to fumes. A failure to heed this
precaution can result in electric shock or fires.
Electric Shock from High Voltages
 Internally, the system uses maximum voltages of AC 240 V and DC 15 kV.
Touching any of the internal components or circuits when the system is powered on can
potentially result in severe injury or death from electric shock.
Do not remove the cover from the system.
When opening the electron gun and other components for maintenance purposes, be
sure to turn off the earth leakage breaker and the power switch, and unplug the power
cord before commencing the work.
Electric Shock from Improper Grounding
 When connecting the main unit to the power supply, be sure to use the grounded power
cable that satisfies law and rule at the site.
Using a power cable that doesn't satisfy can potentially cause electric shock. Also, be
sure to connect the power cable to a grounded power outlet.
If a grounded power outlet is not available for some reason, provide a grounded table
tap or a conversion adapter. In such a case, be sure to provide an appropriate
grounding. Use a grounding wire with a minimum core wire size of 2.0 mm. In addition,
for connection use a minimum screw diameter of M4 and a thread count of 3. Be sure to
plug it in securely.
