Switch on the AC load(s). The GREEN "POWER" LED (2, Fig 6.1) should remain lighted
for normal operation of the load.
9.3 POWERING ON THE LOADS
After the inverter is switched on, it takes a finite time to become ready to deliver full
power. Hence, always switch on the load(s) after a few seconds of switching on the
inverter. Avoid switching on the inverter with the load already switched on. This may
prematurely trigger the overload protection.
When a load is switched on, it may require initial higher power surge to start. Hence, if mul-
tiple loads are being powered, they should be switched on one by one so that the inverter is
not overloaded by the higher starting surge if all the loads are switched on at once.
9.4 TEMPERATURE CONTROLLED COOLING FAN
The cooling fan (behind the cooling fan discharge opening 6, Fig 6.1) 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 temperature of this hot spot
reaches 55°C ± 3°C, the fan is switched ON. The fan will be automatically switched OFF
once the hot spot cools down to 45°C ± 3°C. Please note that the fan may not come on at
low loads or if the ambient temperature is cooler. This is normal.
9.5 INDICATIONS FOR NORMAL OPERATION
When the inverter is operating normally and supplying AC load(s), the GREEN "POWER" LED
(2. Fig 6.1) will be lighted. Please see Section 10, "Protections" and Section 11 "Troubleshoot-
ing Guide" for symptoms of abnormal operation.
9.6 NO LOAD DRAW (IDLE CURRENT)
When the ON/OFF Switch (1, Fig 6.1) is turned 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 ON/OFF
switch (1, Fig 6.1) on the inverter to prevent unnecessary current drain from the battery.
i
INFO
When the inverter is turned OFF using the optional Remote Control RC-15A,
some control circuitry in the inverter is still alive and will draw very low current.
Therefore, to prevent any drain from the battery, switch OFF the inverter from
the ON/OFF switch (1, Fig 6.1) provided on the front panel of the inverter.
