To ensure proper operation of the device keep inside temperature below 70°C.
Operation at

°𝐶
inside temperature is only possible during 240 consecutive hours.
For this the temperature sensor on the RSL8 board can be used; see board documentation for
details
Important Note
Maximum ambient temperature is highly dependent on mounting, air flow and CPU/GPU load; with the
Intel Thermal Monitoring
Technologies
the processor automatically reduces the internal CPU when the critical thermal trip points are reached to prevent
damage.
