1.1 Before You Begin

This evaluation module is not encapsulated and has exposed terminals with voltages that are connected to the main power supply. The following warnings are noted for the safety of anyone using or working close to the UA78LEVM-075. Observe all safety precautions.

WARNING:

Failure to adhere to these steps or to not heed the safety requirements at each step may lead to shock, injury, and damage to the hardware. Texas Instruments is not responsible or liable in any way for shock, injury, or damage caused by negligence or failure to heed advice. If you are not trained in the proper safety of handling and testing power electronics please do not test this evaluation module.

WARNING:

Danger: HIGH VOLTAGE! This evaluation board is intended for professional use only. This board has exposed high voltages. Do not operate this board without proper high-voltage and high-current safety practices. Read this user guide carefully before testing with UA78LEVM-075. Use floating measurement equipment such as high-voltage differential scope probes and see Section 3 and Section 4 for proper EVM setup and test equipment connection.

CAUTION:
