3-6-3. The AC load watt bar graph indicates the power drawn from
the inverter. For long term operation, the watt indicator should
remain in the green and orange area of the bar graph.
Short term operation is possible with watt indicator in the red
area.If the watt indicator rises to high values the bar will flash
and the inverter will shut down to protect itself.
3-6-4. Over voltage indicator:
The over voltage indicator indicates that the inverter has shut
itself down because the maximum input voltage is exceeded.
3-6-5. Under voltage indicator:
The under voltage indicator indicates that the inverter has shut
it self down because the input voltage is below the minimum
level.
3-6-6. Over temp indicator:
The over temp indicator indicates that the inverter has shut
itself down because the maximal temperature has been
exceeded. The inverter may overheat because it has been
operated at power levels above its rating, or because it has
been installed in a location which does not allow it to dissipate
heat properly. The inverter will restart automatically, once it has
cooled off.
3-6-7. Overload indicator:
The overload indicator indicates that the inverter has shut itself
down because the output has been short circuited or
drastically overloaded.
Switch the ON/OFF switch to OFF, correct the fault condition,
and then switch the ON/OFF switch back to ON to reset the
unit.
