3.3.1 High Voltage Safety Considerations

When connecting to any of the high voltage networks, TI recommends that extreme safety precautions are taken. The user must assume the entire board is live with high voltage once an HV connection is made. The high voltage connection points and the areas on the EVM where these voltages are dissipated are shown in the figure below. Extra care must be taken around this area of the EVM.
