Electrical connection

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.

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.

Electrical Safety and Power Supply

Only connect the product to electric circuits with safety extra-low voltage in accordance with IEC 61140 (devices of class III) within the voltage limits for accessible parts as per IEC 61010-1.
Comply with the connection and setting values (see Technical specifications).
The power supply for the product must be safely disconnected from the mains power. For example, use a vehicle battery or a suitable lab power supply.
Only use lab power supplies with dual protection for the supply network (with double/reinforced insulation (DI/RI)).
The power supply must be suitable for use according to the ambient conditions for the product.
It is possible to discharge the vehicle battery in regular operation and long standby operation.
Central load-dump protection is required for operation.

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.

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.

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.

Ensure that the connections of the power supply are easily accessible.

De-energizing the product

Disconnect the product from the power supply in one of the following ways:

Switch off the laboratory power supply for the test setup.
Disconnect the test setup's connection to the vehicle battery.
Remove the power cord.
Remove all cables from the product.
