SAFETY REQUIREMENTS AND PROTECTIVE REGULATIONS
6.1
EMC
An EMC test of the board alone is not intended, as it is not meaningful for the customer's application, as the passing of these
tests is essentially determined by the installation situation, wiring, operating state, design of the housing, etc.
During development, however, care was taken to avoid or filter potential sources of interference on the TQMa6ULxL as far as
possible.
6.2
ESD
Most of the interfaces on the MBa6ULxL are protected against electrostatic discharge.
6.3
Operational safety and personal security
Due to the occurring voltages (
≤
30 V DC), tests with respect to the operational and personal safety have not been carried out.
The superior overall system in connection with the MBa6ULxL is defined by the end customer.
7.
CLIMATIC AND OPERATIONAL CONDITIONS
The MBa6ULxL is designed as an industrial single-board PC that meets all industry standards. Special attention was paid to the
temperature range from –40 °C to +85 °C. The possible temperature range strongly depends on the installation situation (heat
dissipation via the housing), so no fixed value can be specified for the MBa6ULxL. A cooling system is essential in most
applications. It is the user’s sole responsibility to define a suitable heat sink (weight and mounting position) depending on the
specific mode of operation (e.g., dependence on clock frequency, stack height, airflow, and software). Inadequate cooling
connections can lead to overheating of the MBa6ULxL and thus malfunction, deterioration or destruction.
In general, reliable operation is possible when the following conditions are met:

7.1
Protection against external effects
Protection class IP00 was defined for the MBa6ULxL. There is no protection against foreign objects, touch or humidity.
7.2
Reliability and service life
No detailed MTBF calculation was performed for the MBa6ULxL.
The MBa6ULxL is maintenance-free.
It is designed for a service life of 10 years and also to be insensitive to shock and vibration.
