1.4.1 Before You Begin

The following warnings and cautions are noted for the safety of anyone using or working close to the BQ41Z90 EVM. Observe all safety precautions.

BQ41Z90 Warning The BQ41Z90EVM 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.
BQ41Z90 Warning The BQ41Z90EVM is not rated as a high voltage EVM, has smaller clearances than normally used on high voltage boards and does not have an isolation boundary. If you apply high voltage to this board, all terminals should be considered high voltage. Electric shock is possible when connecting the board to live wire. The board should be handled with care by a professional. For safety, use of isolated test equipment with overvoltage and overcurrent protection is highly recommended.
BQ41Z90 Caution Do not leave the EVM powered when unattended.
CAUTION:

The default settings of the BQ41Z90 do not limit performance to the ratings of the EVM. Set all protections appropriately and limit current for safe operation.

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 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 Specification Table.

CAUTION:

Some power supplies can be damaged by application of external voltages. If using more than 1 power supply, check your equipment requirements and use blocking diodes or other isolation techniques, as needed, to prevent damage to your equipment.

CAUTION:

The communication interface is not isolated on the EVM. Be sure no ground potential exists between the computer and the EVM. Also be aware that the computer is referenced to the Battery- potential of the EVM.

CAUTION:

Connections for rated current must be made at the terminal block. Test points are not rated for the board current.
