voltage will continue to be available. This warning alarm indicates that the battery is
running low and that the inverter will be shut down after sometime if the voltage at
the inverter terminals further drops to 10V. The alarm will reset automatically when
voltage rises above 10.5V.
Shut-Down Due to low Dc input Voltage: If the inverter continues to power the load
after the low dc input voltage buzzer alarm is sounded, it will shut down completely
when the dc input voltage further drops below 10V. There will be no Ac output voltage
and the alarm will continue to sound. The unit will be reset automatically when the
input voltage rises to 11.3V.
Shut-down Due to High Dc input Voltage: If the voltage at the dc input terminals ex-
ceeds 16.5V, the inverter will be shut down completely. The unit will reset automatically
when input voltage drops below 16.5V.
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 and the
negative of the battery should be connected to the negative dc input terminal of the
inverter. 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 external dc
side fuse and the dc input fuses inside the inverter. If the dc side fuses are blown, the
inverter will be dead. There will be no indication of any voltage on the colored lEd
bar graph voltage indicator and also, there will be no Ac output. The fuses should be
replaced with the correct size of fuses shown under specifications. If the unit does not
work after replacing the external and internal fuses, it has been permanently damaged.
Please call Technical Support for assistance.
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 a particular upper limit, the Ac output
of the inverter is shut down temporarily. The rEd over Temp lEd (b, fig. 7.1 or 7.2) is
lighted and a buzzer is sounded. The unit will automatically reset after the unit has
cooled down.
Shut Down Due to overload or Short circuit on Ac output Side: Shut down will be
activated under the following conditions:
• Continuous overload higher than the rated Maximum Continuous Active Power
output rating
• Short time overload higher than the Surge Output Power Rating
• Short circuit
when this protection is activated, the Ac output voltage will be shutdown and the
red overload lEd (c, fig 7.1 or 7.2) will be lighted. the unit will remain latched in shut
down condition till it is reset manually. before resetting, remove the possible cause
of overload or short circuit. To reset, switch off the unit with the help of the on /off
