1.2 Before You Begin

The following warnings and cautions are noted for the safety of anyone using or working close to the TPSM843B22EVM. Observe all safety precautions.

GUID-6761E24C-8B52-48BD-BC6B-E5CE7CD12508-low.pngCautionThe TPSM843B22EVM may become hot during operation due to dissipation of power in some operating conditions. Avoid contact with the board. Follow all applicable safety procedures applicable to your laboratory.

Caution Hot surface.

Contact may cause burns.

Do not touch!

WARNING:

The circuit module has signal traces, components, and component leads on the bottom of the board. This may result in exposed voltages, hot surfaces or sharp edges. Do not reach under the board during operation.

CAUTION:

Some power supplies can be damaged by application of external voltages. If using more than one power supply, check your equipment requirements and use blocking diodes or other isolation techniques, as needed, to prevent damage to your equipment.
