Attention:

TI intends this EVM to be operated in a lab environment only and does not consider the device to be a finished product for general consumer use.

TI Intends this EVM to be used only by qualified engineers and technicians familiar with risks associated with handling high-voltage electrical and mechanical components, systems, and subsystems.

DANGER:

High voltage! The board operates at voltages and currents that can cause shock, fire, or injury if not properly handled or applied. Electric shock possible when connecting board to live wire. Board should be handled with care by a professional.

For safety, use of isolated test equipment with overvoltage/overcurrent protection is required. If possible, tests should be conducted in an enclosure rated for high voltage testing.

WARNING: Hot surface! Contact can cause burns. Do not touch! Some components can 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 can be present.
CAUTION: Do not leave the EVM powered when unattended.
Note:

TI recommends using an external power supply or power accessory which complies with applicable regional safety standards such as (by example) UL, CSA, VDE, CCC, PSE, and so forth.

1. Refer to output power and individual motor characteristics to determine output current.
