General TI High Voltage Evaluation User Safety Guidelines
Always follow TI’s set-up 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 the safety of those working around you. Contact TI’s Product Information
Center
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/or burn hazards.
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 suitably qualified, you should immediately stop from further
use of the HV EVM.
•
Work Area Safety:
–
Maintain a clean and orderly work area .
–
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 access.
–
All interface circuits, power supplies, evaluation modules, instruments, meters, scopes and other
related apparatus used in a development environment exceeding 50 V
RMS
/75 VDC must be
electrically located within a protected Emergency Power Off (EPO) protected power strip.
–
Use a 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. Confirm 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 hook-ups and other application needs, while still assuming the EVM circuit
and measuring instruments are electrically live.
–
When 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.
