temperature controlled cooling Fan
The cooling fan is thermostatically controlled. Temperature of a critical hot spot inside
the inverter is monitored to activate the fan and the over temperature shut-down.

will be automatically switched offoncethehotspotcoolsdownto42°C.Pleasenote
that the fan may not come on at low loads or if the ambient temperature is cooler. This
is normal.
