1.1.4 General operating and safety strategy of Technica
Engineering’s Products
Technica Engineering’s products are designed for operation in automotive systems
and for supply voltages of nominal 12 V or 24 V. The applicable limit values adhere to
the standard norms for 12 V or 24 V automotive onboard power systems
correspondingly and can be found in the mentioned norms.
Should Technica Engineering’s products be operated in voltage ranges beyond those
specified in the norms, which represents a breach of the conditions of operation, then
this will void the product warranty and Technica Engineering will assume no liability
whatsoever of the results and/or consequences thereof.
This is especially valid whenever the voltage level reaches or exceeds the limits of the
low-voltage directive. In this case, damage to the devices cannot be excluded. Due to
the manufacturing characteristics of the devices, there is no imminent fire hazard from
the device itself, if the devices are being operated in an environment according to the
conditions of use. A secondary fire hazard cannot be excluded, should those
conditions not be met. A protection against overvoltage cannot be provided in such a
breach of the conditions of use.
1.1.5 General design rules for the power supply of Technica
Engineering’s products
The power supply circuit of Technica Engineering’s products are equipped with self-
protection components. This automatic function protects the devices against
excessive temperature and too high supply-voltage by switching the device off. This
automatic switch-off function is independent of any software function.
The root-cause of excessive temperature in the power supply circuit can eventually be
due to a too high environment temperature or due to an internal failure of the device.
In both cases, the automatic switch-off function will switch-off the power supply from
the device to avoid further damage.
The protection against too high supply-voltage protects the device even in case of an
internal failure of the Technica Engineering device.
