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

Guidelines

WARNING

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 

http://

support/ti./com

 for further information.

Save all warnings and instructions for future reference.

WARNING

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.

 If you are not suitably qualified, you should immediately stop from further use of 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 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.

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 stable and nonconductive work surface.
f.

Use adequately insulated clamps and wires to attach measurement probes and instruments. No 
freehand testing 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 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 EVM readiness is complete, energize the EVM as intended.

WARNING

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 EVM in an adequate lucent plastic box with interlocks to protect from accidental touch.

Limitation for safe use:

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