Sontheim_Telemetry_Verona_Gen 4_operations manual.docx Version of the Document: 2.1

Control units must be stored with a mean relative humidity of 60% and at a temperature between

-10 °C and +50 °C. Storage temperatures between -40 °C and +90 °C are briefly permissible,

for up to 100 hours.

After a storage time of more than 5 years, the ECU must be examined by the manufacturer.

7.8. Notes on Wiring and Circuitry

The electronics and the power outputs of an ECU must be fed from the same power source.

When wiring the output stages, the maximum cumulative output current for each output stage

group should be noted. The cumulative output current means a permanent, simultaneous

actuation of the output stages.

The product may only be wired when it is de-energized.

Lines to the electronics must not be routed close to other power-conducting lines in the system,

or vehicle.

The wiring harness should be fixated mechanically in the area in which the ECU is installed

(spacing < 150 mm). The wiring harness should be fixated so that in-phase excitation with the

controller occurs (e.g. at the controller bolting point).

If possible, lines should be routed in the vehicle interior.

If the lines are routed outside the vehicle, make sure that they are securely fixed.

Lines must not be kinked or twisted, must not rub against edges and must not be routed through

sharp-edged ducts without protection.

Lines are to be routed with sufficient spacing to hot or moving vehicle parts.

Digital outputs must not be linked or bridged.

Digital outputs with current measurement must not be used to light bulbs (due to very low cold

resistance).

The voltages supplies sources must not be pulled up by an external connection, e.g. the

application of a higher voltage, because they operate only as a voltage source but not as a

voltage sink. Pulling up a sensor supply may result in unexpected malfunctions and damage of

the ECU in lasting operation.

The high side outputs must not be externally connected to battery.

7.9. Intended Use

The ECU is designed for use in automotive applications as vehicle, trucks, busses and trailer

and mobile working machines provided no limitations / restrictions are made to certain

application areas in this data sheet.

Operation of the ECU must generally occur within the operating ranges specified and released

in data sheet, particularly with regard to voltage, current, temperature and other described

environmental influences.

Use outside of the specified and released boundary conditions may cause damage to

components, which could result in consequential damage to the vehicle, trucks, busses, trailer

and mobile working machine.

7.10. Improper Use

Any use of the ECU other than that described in chapter „Intended use“ is considered to be

improper.

Use in explosive areas is not permissible.

Damage resulting from improper use and/or from unauthorized interference in the component

not described in this manual or data sheet render all warranty and liability claims void with

respect to the manufacturer.
