General operating and safety strategy of TE 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 for 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. 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 TE
products
The power supply solution of Technica Engineering’s products is equipped with a self
-
protection mechanism. This automatic function protects the internal electronic
components against excessive temperature and too high supply-voltage by switching
the device off. This automatic switch-off function is independent of any software
function. Excessive temperatures in the device, can be caused by high environmental
temperatures or internal failures of the device. The device can protect itself by shutting
down its own power supply avoiding further damage to itself.
The operator/user of this devices must take measures for the right protection of the
power supply lines and the according connector. The maximum power consumption
of the Technica Engineering products is written in this user manual.
Please take care that some of the products are working with a step-up converter. So,
the current needed in case of undervoltage conditions must be considered as higher
than at nominal voltage level. The user must choose the right fuse or other over current
protection measures.
