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.

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 and/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.
- Work Area Safety
- Keep work area clean and
- Qualified observer(s)
must be present anytime circuits are energized.
- 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
- 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.
- Use stable and non
conductive work surface.
- Use adequately insulated
clamps and wires to attach measurement probes and instruments. No
freehand testing whenever possible.
- 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.
- 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 TI HV EVM
power has been safely de-energized.
- 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
- After EVM readiness is
complete, 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.
- Personal Safety
- 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.
