1 General TI High Voltage Evaluation User Safety Guidelines
Always follow TI's set-up and application instructions, including the use of all interface components within the
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 at
http://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/or burn hazards.
The term TI HV EVM refers to an electronic device typically provided as an open framed, unenclosed PCB
(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 is strictly prohibited by Texas
Instruments. If you are not suitably qualified, you must 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 VRMS/75 VDC must be electrically located
within a protected Emergency Power Off (EPO) 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.
– After confirming the EVM is de-energized, proceed with the 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.
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 like latex gloves and safety glasses with side shields, or protect the
EVM from accidental touch in an adequate translucent plastic box with interlocks.
•
Limitation for Safe Use:
SNOU178A – OCTOBER 2020 – REVISED FEBRUARY 2021
