OPERATION
Powering on the loads
After the inverter is switched on, it takes a finite time for it 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 (2) 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 this 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 inve
rter.
When the inverter is switched on, the LED indicator (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 output receptacles.
Switch on the AC load(s). The green LED should remain lighted for normal operation
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.
Indications for normal operation.
When the inverter is operating normally and supplying AC load(s), the LED (3) will be
green. In case of abnormal operation, other displays and alarms will be activated. Please
see under
“Protections Against Abnormal Conditions” on page 24.
