Shut-down due to reversal of polarity at the DC input terminals. 

The positive of the battery should be connected to the positive DC input terminal of the 
inverter, (the tip of the cigarette lighter plug), and the negative of the battery should be 
connected to the negative DC input terminal of the inverter (The spring loaded bow type 
contacts of the cigarette lighter plug). A reversal of polarity (the positive of the battery 

wrongly connected

 to the negative DC input terminal of the inverter and the negative 

of the battery 

wrongly connected

 to the positive DC input terminal of the inverter) will 

blow the DC side fuses inside the inverter. If the DC side fuse is blown, the inverter will 
be dead. The LED (2) will be switched off and there will be no AC output. The internal 
fuse should be replaced with the correct size of fuse shown under specifications. If the 
unit does not work after replacing the fuse, it has been permanently damaged. 

Shut-down due to over-temperature.

 In case of failure of the cooling fan or in the case 

of inadequate heat removal due to higher ambient temperatures / insufficient air exchange, 
the temperature inside the unit will increase. The temperature of a critical hot spot inside 
the inverter is monitored and at 95° C, the AC output of the inverter is shut down 
temporarily. The LED (2) turns orange and a buzzer is sounded. The unit will automatically 
reset after the hot spot has cooled down to 70° C. 

Shut down due to overload.

 The inverter can provide a higher than normal instantaneous

(< 1 second) power limited to the surge power rating of the inverter. Also, the inverter 
can provide continuous power limited to the continuous power rating of the inverter.
If there is an overload beyond the 

specified limits, the AC output of the unit will be shut down permanently. LED (2) will turn 
orange and buzzer alarm will be sounded. The unit will be required to be reset manually 
by switching the unit off and on again. Before switching on the unit, please remove the 
cause of the overload.
