DANGER

DO NOT TOUCH THE BOARD WHEN IT IS ENERGIZED AND ALLOW ALL COMPONENTS TO DISCHARGE COMPLETELY PRIOR HANDLING THE BOARD.

HIGH VOLTAGE CAN BE EXPOSED ON THE BOARD WHEN IT IS CONNECTED TO POWER SOURCE. EVEN BRIEF CONTACT DURING OPERATION MAY RESULT IN SEVERE INJURY OR DEATH.

Please sure that appropriate safety procedures are followed. This evaluation kit is designed for engineering evaluation in a controlled lab environment and should be handled by qualified personnel ONLY. Never leave the board operating unattended.

WARNING

Some components can be hot during and after operation. There is NO built-in electrical or thermal protection on this evaluation kit. The operating voltage, current, and component temperature should be monitored closely during operation to prevent device damage.

CAUTION

This product contains parts that are susceptible to damage by electrostatic discharge (ESD). Always follow ESD prevention procedures when handling the product.
