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
multiple 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.
Switching the inverter on/oFF
Before switching on the inverter, check that all the AC loads have been switched off. The
oN/off switch (1) on the front panel of the inverter is used to switch on and switch off
the inverter. This switch operates a low power control circuitry, which in turn controls all
the high power circuitry.

cAUtion!
Please note that the oN/off switch is not switching the high power battery
input circuit. Parts of the DC side circuit will still be alive even when the switch
is in the off position. Hence, disconnect the DC and AC sides before working
on any circuits connected to the inverter.
When the inverter is switched on, the LED indicator (2, figs. 6.1, 6.2, 6.3) will turn
GREEN. This LED
indicates that the inverter is operating normally. Under normal operating conditions,
AC output voltage will now be available at the AC outlet (5).
Switch on the AC load(s). The GREEN LED (2) should remain lighted for normal opera-
tion of the load.
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 temperature of this hot spot reaches 48°C, the fan is switched oN. The fan
will be automatically switched off once the hot spot cools down to 42°C. Please note
that the fan may not come on at low loads or if the ambient temperature is cooler. This
is normal.
