Always follow TI's setup and application instructions, including use of all interface components within their recommended electrical rated voltage and power limits. Always use electrical safety precautions to help ensure your personal safety and those working around you. Contact TI's Product Information Center for further information.

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

1. Work Area Safety:
   1. Keep work area clean and orderly.
   2. Qualified observers must be present any time circuits are energized.
   3. Effective barriers and signage must be present in the area where the TI HV EVM and its interface electronics are energized, indicating operation of accessible high voltages may be present, for the purpose of protecting inadvertent access.
   4. All interface circuits, power supplies, evaluation modules, instruments, meters, scopes, and other related apparatus used in a development environment exceeding 50 Vrms and 75 VDC must be electrically located within a protected Emergency Power Off (EPO) protected power strip.
   5. Use stable and non-conductive work surface.
   6. Use adequately insulated clamps and wires to attach measurement probes and instruments. No freehand testing whenever possible.
2. Electrical Safety:
   1. As a precautionary measure, it is always good engineering practice to assume that the entire EVM may have fully accessible and active high voltages.
   2. DE-energize the TI HV EVM and all its inputs, outputs, and electrical loads before performing any electrical or other diagnostic measurements. Re-validate that the TI HV EVM power has been 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, while still assuming the EVM circuit and measuring instruments are electrically live.
   4. Once EVM readiness is complete, energize the EVM as intended.
   WARNING:

   High voltages of DC are present on this evaluation board during operation and even for a while after powering off. To evaluate this module, the individuals involved must be qualified with adequate knowledge and skills of high voltage from electrical engineering practice. Severe injury, including death, can occur from insufficient personal capability.

   The DC voltage source with isolation should meet the IEC60950 reinforced insulation standards are suggested to be necessary for performing evaluation on this EVM.

   Extreme caution should be taken to eliminate the possibility of an electric shock and heat burn. Please see General Texas Instruments High Voltage Evaluation (TI HV EVM) User Safety Guidelines for safety concerns and precautions.

   Read and understand this user's guide thoroughly before starting any physical evaluation.

1. Personal Safety:
   1. Wear personal protective equipment, for example, latex gloves or safety glasses with side shields or protect the EVM in an adequate lucent plastic box with interlocks from accidental touch.

EVMs are not to be used as all or part of a production unit.
