LOW INPUT VOLTAGE ALARM
An alarm will sound when the voltage at the input terminals of the inverter drops to
10.5 Volts.(For 12V DC Input )This is an indication that either the battery terminal
voltage has dropped due to its discharged condition and needs to be recharged or
there is an excessive voltage drop across the wires connecting the inverter to the
battery (due to use of thinner and longer length of wires that will produce higher
voltage drop at higher loads or due to loose connections). The user should stop
operation of the electronic device at this time since the inverter will shut down
automatically shortly thereafter, when the input voltage at the inverter further drops
to 10 Volts. In case the alarm is due to the discharged condition of the battery, start
your engine to recharge the battery /use an appropriate battery charger.
If the low voltage alarm sounds when the battery is fully charged, follow the steps for
solving lack of output power in the Troubleshooting Guide at the end of this manual.
NOTE: It is normal for the alarm to sound while the unit is being connected
to or disconnected from the power source. This is not indicative of a problem.

TROUBLESHOOTING GUIDE

POSSIBLE CAUSE(S)
Over Temperature Shutdown
In case the fan fails or if the cooling
is inadequate due to higher ambient
temperature or restricted airflow,
the temperature inside the inverter
will start rising. Temperature rise
is sensed at one of the DC side
Mosfets. If this temperature
exceeds 80℃ , the AC output will
be switched off.
No activity due to loss of DC
input power to the inverter
1. If there is no voltage at the DC
input terminals:
• Battery is dead
• External DC input fuse is blown
• Loose connection along the
circuit from the battery to the
DCinput terminals
2. If there is voltage at the DC
input terminals:
• Internal DC input fuses
have blown

SUGGESTED REMEDIES
1. The inverter will remain
latched inthis shut down
condition and will be required
to be reset manually by
switching OFF, waiting for
15 minutes and switching
ON again.
2. Before using the inverter again,
please ensure that the cause
of over temperature has
been removed

connections and fuses or
