TI Intends this reference design to be used only by qualified engineers and technicians familiar with the risks associated with handling high-voltage electrical and mechanical components, systems, and subsystems.
Hot surface! Contact can cause burns. Do not touch! Some components can reach high temperatures > 55°C when the board is powered on. Do not touch the board at any point during operation or immediately after operating, because high temperatures can be present.
Do not leave the design powered when unattended.
