Connection to the power supply

DANGER 

Undefined vehicle behavior due to an ECU reset

If the external power supply to the ETK is interrupted (e.g. cut, disconnected, etc.), this may lead to the ECU being reset.

  • Connect the internal power supply of the ECU to the ETK in addition to the external power supply.

  • If this is not possible, ensure that the external power supply to the ETK is not interrupted during operation.

WARNING 

Risk to life from electric shock

If an unsuitable power supply is used, this may generate a hazardous electrical voltage.

  • Use a power supply that is permitted for the product.

NOTICE 

Damage to the electronics due to potential equalization

The cables' shield may be connected to the housing, the ground or the ground for the product's power supply. If there are different ground potentials in the test setup, equalizing currents can flow between the products via the cables' shield.

Take account of different electric potentials in your test setup and take appropriate measures to prevent equalizing currents.

De-energizing the product

  1. Disconnect the product from the power supply.

  2. Switch off the laboratory power supply for the test setup.

  3. Disconnect the test setup's connection to the vehicle battery.

  4. Remove the power cord.
