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 http://
support.ti.com for further information.
Save all warnings and instructions for future reference.
Failure to follow warnings and instructions can 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 observers must be present anytime circuits are energized.
– Effective barriers and signage must be present in the area where the TI HV EVM and 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 50 VRMS/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 can
have fully accessible and active high voltages.
– De-energize the TI HV EVM and all 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
WARNING: While the EVM is energized, never touch the EVM or its electrical circuits as
the EVM and circuits can be at high voltages capable of causing electrical shock hazard.
•Personal Safety:
– Wear personal protective equipment, for example, latex gloves and/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.
Safety and Precautions
The EVM is designed for professionals who have received the appropriate technical training, and is designed
to operate from an AC power supply or a high-voltage DC supply. Please read this user guide and the safety-
related documents that come with the EVM package before operating this EVM.
