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.
