9.3 TEMPERATURE CONTROLLED COOLING FAN
One thermostatically controlled cooling fan has been provided for forced air cooling.
Temperature of a critical hot spot inside the inverter is monitored to activate the fan
and the over temperature shut-down. The fan will be automatically switched OFF
once the hot spot cools down. Please note that the fan may not switch ON at low
loads or if the ambient temperature is cooler. This is normal.
9.4 INDICATIONS FOR NORMAL OPERATION
When the inverter is operating normally and supplying AC load(s), the Green LED
marked “POWER” will be lighted.
9.5 NO LOAD DRAW (IDLE CURRENT)
When the unit is switched ON, all the circuitry inside the inverter becomes alive
and the AC output is made available. In this condition, even when no load is being
supplied (or, if a load is connected but has been switched OFF), the inverter draws a
small amount of current from the batteries to keep the circuitry alive and ready to
deliver the required power on demand. This is called the “Idle Current” or the “No
Load Draw”. Hence, when the load is not required to be operated, turn OFF the
inverter to prevent unnecessary current drain from the battery.
9.6 LED INDICATOR
Green:
POWER ON
Orange:
Protections (low voltage shutdown, high voltage shutdown, over load
shutdown, short circuit shutdown, or over temperature shutdown).
Red blink:
The inverter is turned off by remote controller and the Power On switch
is at ON position (blinks every 2 seconds).
