WARNING: TI intends this reference design to be operated in a lab environment only and does not consider it to be a finished product for general consumer use. The design is intended to be run at ambient room temperature and is not tested for operation under other ambient temperatures. TI intends this reference design to be used only by qualified engineers and technicians familiar with risks associated with handling high-voltage electrical and mechanical components, systems, and subsystems. There are accessible high voltages present on the board. The board operates at voltages and currents that may cause shock, fire, or injury if not properly handled or applied. Use the equipment with necessary caution and appropriate safeguards to avoid injuring yourself or damaging property. |
CAUTION: Do not leave the design powered when unattended. |
WARNING: High voltage! There are accessible high voltages present on the board. Electric shock is possible. The board operates at voltages and currents that may cause shock, fire, or injury if not properly handled. Use the equipment with necessary caution and appropriate safeguards to avoid injuring yourself or damaging property. For safety, use of isolated test equipment with over-voltage and over-current protection is highly recommended. TI considers it the user's responsibility to confirm that the voltages and isolation requirements are identified and understood before energizing the board or simulation. When energized, do not touch the design or components connected to the design. |
WARNING: Hot surface! Contact may cause burns. Do not touch! Some components may reach high temperatures >55°C when the board is powered on. The user must not touch the board at any point during operation or immediately after operating, as high temperatures may be present. |
