16.5.5 Thermal behavior
In the case the ambient temperature exceeds +50°C (for vertical mounting), the load power is
to be reduced by 2.5% per degree Celsius increase in temperature. If the load is not reduced,
the device will run into thermal protection by switching off; the device will go in hick‑up mode
and will recover when the ambient temperature is lowered or the load is reduced as far as
necessary to keep the device within normal working conditions.
