Safety and Usage of High Voltage Power Supply 3

Ground
Use insulators having highinsulation property
Never touch stripped wire
When handling high voltage, failure to observe safety precautions can result in electric shock, or even death in the worst case.
Be sure to carefully observe the following safety precautions.
Always connect a ground wire
In order to avoid discharging electricity in a manner that will cause bodily harm, either cover the object with an insulator that has
sufficient dielectric strength, or cover it with an object that has ground potential so that electricity is not discharged to a different location.
When operating equipment, avoid contact with parts that output high voltage as well as high voltage terminals.Otherwise, electric
shock could occur. During normal operation and test operation, extremely high voltage is applied to the terminals. Touching them
could lead to a fatal accident.
With high voltages of 300 V or more, there is a risk of electric shock due to the discharge of electricity even if you do not touch an
electrode directly. Either cover electrodes and other high-voltage areas with insulators that have sufficient dielectric strength, or cover
them with grounded conductive material, to ensure that these areas cannot be touched directly.
Considering the risk of electric shock accidents, if personnel who are experienced in the operation of high voltage power supplies
and who know how to perform appropriate first aid measures are not nearby, avoid any contact with high voltage power supplies.
In addition, if inexperienced personnel will be operating a high voltage power supply, explain the necessary precautions in advance
(such as avoiding contact with hazardous areas) and make sure they completely understand the dangers before allowing them to
perform the operations.
