2.3.1 Admissible load current depending on the site altitude
Site altitude
In the case of air cooling, it must be noted that the effectiveness of the cooling
is reduced as the site altitude increases. As a result, the ampacity of the
IPC 300 decreases as the site altitude increases, as shown in the diagram.

Destruction through overheating:
In the event of operation at maximum load current over an extended period,
the heat sink and its surroundings heat up.
The device temperature must not exceed 100 °C.
At a device temperature of >100 °C, the message "Warning - high tempera-
ture" is displayed.
At a device temperature of >105 °C, the output level is gradually reduced by
10 % each time the temperature increases by one degree.
At a device temperature of >115 °C, the power controller is completely
switched off.
