2 Warnings and Cautions

Observe the following precautions when using the TPS92519EVM-169.

CAUTION:
GUID-43326919-E3B7-40C5-8472-640FB412483D-low.gif
Caution! Do not leave EVM powered when unattended.
HOT SURFACE:
GUID-8DC9289A-0B23-41BC-8E23-B809E04E1A9A-low.gif
Caution Hot Surface! Contact may cause burns. Do not touch. Please take the proper
precautions when operating.
HIGH VOLTAGE:
GUID-69AEB971-E757-40EA-AE0E-D4BACB1CCD9E-low.gif
Danger High Voltage! Electric shock possible when connecting board to live wire. Board must
be handled with care by a professional. For safety, use of isolated test equipment with
overvoltage and overcurrent protection is highly recommended.
WARNING:

GUID-CF0CB7DA-FF79-4AFF-B510-63051BCAB68E-low.gif When choosing your LED component (not included with this EVM), the end user must consult the LED data sheet supplied by the LED manufacturer to identify the EN62471 Risk Group Rating and review any potential eye hazards associated with the LED chosen. Always consider and implement the use of effective light filtering and darkening protective eye wear and be fully aware of surrounding laboratory-type set-ups when viewing intense light sources that can be required to minimize or eliminate such risks in order to avoid accidents related to temporary blindness.
