1.4.1 General Safety Information

The following warnings and cautions are noted for the safety of anyone using or working close to the BQ25756EVM. Observe all safety precautions.

BQ25856EVM WarningThe BQ25756EVM circuit module can become hot during operation due to dissipation of heat. Avoid contact with the board. Follow all applicable safety procedures applicable to your laboratory.
CAUTION: Hot surface. Contact can cause burns. Do not touch!
BQ25856EVM WarningThe BQ25756EVM has smaller clearance and creepage than normally used on high voltage boards as well as not having an isolation boundary. If the user applies high voltage to this board, then all terminals are considered high voltage and hazardous live. Electric shock is possible when connecting the board to live wire. The board needs to be handled with care by a professional. For safety, use of isolated test equipment with various protection features (such as overvoltage and overcurrent) is recommended.
BQ25856EVM WarningHigh voltages that can cause injury exist on this evaluation module (EVM). Please verify all safety procedures are followed when working on this EVM. Never leave a powered EVM unattended.
BQ25856EVM WarningHigh voltage can be present on board capacitors after power down. Properly check and discharge all on-board energy reservoir after EVM power down.
BQ25856EVM CautionDo not leave EVM powered when unattended.
CAUTION: The communication interfaces are not isolated on the EVM. The use of digital isolators is recommended. Verify all high voltage safety precautions are observed during testing.
CAUTION: Connections for rated current must be made at the terminal block. Test points are not rated for the board current.
CAUTION: The circuit module can be damaged by over temperature. To avoid damage, monitor the temperature during evaluation and provide cooling, as needed, for your system environment. Do not operate beyond the current and voltage limits in the Section 2.3.
CAUTION: Test equipment can be damaged by application of external voltages. Check your equipment requirements and use blocking diodes or other isolation techniques, as needed, to prevent damage to your equipment.
CAUTION: The circuit module has signal traces, components, and component leads on the bottom of the board. This can result in exposed voltages, hot surfaces or sharp edges. Do not reach under the board during operation.
CAUTION: The default settings of the BQ25756 is possibly not designed for the user's application. Verify the EVM settings are set appropriately for test setup before device power up. Set all protections appropriately and limit current for safe operation.
CAUTION: The board has no fuse installed and relies on the external voltage source current limit to verify circuit protection.
