Protections
The inverter has been provided with protections detailed below:
overload / Short circuit Shut Down
Theinvertercanprovideahigherthannormalinstantaneouspower(<1second)limited
tothesurgepowerratingoftheinverter.Also,theinvertercanprovidecontinuous
power limited to the continuous power rating of the inverter. If there is an overload
beyondthesespecifiedlimits,theACoutputoftheunitwillbeshutdownpermanently.
StatusLED(2)willturnoRANGE,theGREENindicationontheGfCIwillbeoffand
buzzer alarm will sound. The unit will be latched in this shutdown condition and will
requiremanualreset.Toreset,switchoff the power oN/offswitch,waitfor3min-
utes and then switch oN again. before switching oNagain,removethecauseofthe
shutdown.
