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. When the
temperatureofthishotspotreaches118.4°f/48°C,thefanisswitchedoN. The fan will
be automatically switched offoncethehotspotcoolsdownto107.6°f/42°C.Pleasenote
that the fan may not come on at low loads or if the ambient temperature is cooler. This is
normal.
