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 verify your personal safety and those working around you.
Contact TI's Product Information Center http://ti.com/customer support for further
information.
Save all warnings and instructions
for future reference.
WARNING: Failure to follow
warnings and instructions can result in personal injury, property damage or death
due to electrical shock and 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, then immediately stop
from further use of the HV EVM.
- Work Area Safety:
- Keep work area clean
and orderly.
- Qualified observers
must be present anytime circuits are energized.
- Effective barriers
and signage must be present in the area where the TI HV EVM and the
interface electronics are energized, indicating operation of
accessible high voltages can 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 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, a good engineering practice to assume is that the entire
EVM can have fully accessible and active high voltages.
- De-energize the TI HV
EVM and all the inputs, outputs and electrical loads before
performing any electrical or other diagnostic measurements.
Revalidate 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.
- Once EVM readiness is
complete, energize the EVM as intended.
WARNING: While the EVM is
energized, never touch the EVM or the electrical circuits, as
the electrical circuits and EVM can be at high voltages capable
of causing electrical shock hazard.
- Personal Safety
- Wear personal
protective equipment e.g. latex gloves or safety glasses with side
shields or protect EVM in an adequate lucent plastic box with
interlocks from accidental touch.
Limitation for safe use:
EVMs are not to be used as all or part
of a production unit.
