2 General Texas Instruments High Voltage Evaluation Module (TI HV EVM) User Safety

Guidelines

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

support/ti./com

for further information.

Save all warnings and instructions for future reference.

Failure to follow warnings and instructions may result in personal injury, property damage, or death

due to electrical shock and burn hazards.

The term TI HV EVM refers to an electronic product 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

™

. Unqualified professionals should immediately stop using the HV EVM.

1. Work Area Safety

a. Keep work area clean and orderly.

b. One or more qualified observers must be present anytime circuits are energized.

c. Effective barriers and signage indicating operation of accessible high voltages must be present in the

area where the TI HV EVM and its interface electronics are energized for the purpose of protecting

inadvertent access.

d. All interface circuits, power supplies, evaluation modules, instruments, meters, scopes, and other related

apparatus used in a development environment exceeding 50Vrms/75VDC must be electrically located

within a protected Emergency Power Off EPO protected power strip.

e. Use a stable and nonconductive work surface.

Use adequately insulated clamps and wires to attach measurement probes and instruments. Do not test

the EVM freehand whenever possible.

2. Electrical Safety

As a precautionary measure, it is always a good engineering practice to assume that the entire EVM may

have fully accessible and active high voltages.

a. De-energize the TI HV EVM and all its inputs, outputs, and electrical loads before performing any

electrical or other diagnostic measurements. Revalidate that TI HV EVM power has been safely de-

energized.

b. With the EVM confirmed de-energized, proceed with the required electrical circuit configurations, wiring,

measurement equipment connection, and other application needs, while still assuming the EVM circuit

and measuring instruments are electrically live.

c. After the EVM is completely ready, energize the EVM as intended.

While the EVM is energized, never touch the EVM or its electrical circuits, as they could be at

high voltages capable of causing electrical shock hazard.

3. Personal Safety

a. 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 to protect it from being accidentally

touched.
