Always follow TI's set up and application instructions, including the use of all interface components within their recommended electrical rated voltage and power limits. Always use electrical safety precautions to help maintain a safe working environment for all. Contact TI's Product Information Center for further information.

The term TI HV EVM refers to an electronic device, typically provided as a printed circuit board assembly that is open framed and unenclosed. These devices are intended strictly for use in development laboratory environments, solely for qualified professional users that have training, expertise, and knowledge of electrical safety risks in the development and application of high voltage electrical circuits. Any other use or application are strictly prohibited by Texas Instruments. If not qualified, immediately stop from further use of the HV EVM.

1. Work area safety:
   1. Keep the work area clean and orderly.
   2. Verify that qualified observers are present at all times when circuits are energized.
   3. To prevent inadvertent access, use effective barriers and signage to indicate that the operation of accessible high voltages are present in the area where the TI HV EVM and interface electronics are energized.
   4. Electrically locate all interface circuits, power supplies, evaluation modules, instruments, meters, scopes, and other related apparatus used in a development environment exceeding 50Vrms, 75VDC within a protected Emergency Power Off EPO protected power strip.
   5. Use stable and non-conductive work surfaces.
   6. Use adequately insulated clamps and wires to attach measurement probes and instruments. Avoid freehand testing whenever possible.
2. Electrical safety:
   1. As a precautionary measure, assume that the entire EVM has fully-accessible and active high voltages.
   2. De-energize the TI HV EVM and all of the inputs, outputs, and electrical loads before performing any electrical or other diagnostic measurements. Revalidate that TI HV EVM power is safely de-energized.
   3. With the EVM confirmed de-energized, proceed with required electrical circuit configurations, wiring, measurement equipment hook-ups, and other application needs. Continue assuming that the EVM circuit and measuring instruments are electrically live.
   4. Once EVM readiness is complete, energize the EVM as intended.
      WARNING: While the EVM is energized, never touch the EVM or the electrical circuits, as high voltages can cause electrical shock hazards.
3. Personal Safety:
   1. Wear personal protective equipment, for example gloves or safety glasses with side shields, or contain the EVM in a lucent plastic box with interlocks to protect from accidental touch.

Do not use EVMs as all or part of a production unit.
