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 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.

1. Work Area Safety:

(a) Keep work area clean and orderly.

(b) Qualified observer(s) must be present anytime circuits are energized.

electronics are energized, indicating operation of accessible high voltages may be present, for the

purpose of protecting inadvertent access.

(d) 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.

(e) Use a stable and non-conductive work surface.

(f) Use adequately insulated clamps and wires to attach measurement probes and instruments. No

freehand testing whenever possible.

2. Electrical Safety:

(a) De-energize the TI HV EVM and all its inputs, outputs, and electrical loads before performing any

electrical or other diagnostic measurements. Revalidate that TI HV EVM power has been safely de-

energized.

(b) 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.

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.

3. Personal Safety:

(a) Wear personal protective equipment e.g. latex gloves and/or safety glasses with side shields or

protect EVM in an adequate lucent plastic box with interlocks from accidental touch.
