PROTECTIVE FEATURES OF THE INVERTER

OVER TEMPERATURE PROTECTION
The unit is cooled by 2-speed fan(s). The fan(s) will run at slower speed up to certain threshold of power
output and at full speed thereafter. In case the fan fails or if the cooling is inadequate due to higher ambient
temperature or restricted air flow, the temperature inside the inverter will be too high and the unit will
automatically shut down. Allow the unit to cool for at least 15 minutes before restarting after a heat-related
shutdown. Unplug unit while cooling.
LOW BATTERY VOLTAGE PROTECTION
This condition is not harmful to the inverter but could damage the power source. The inverter automatically
shuts down when input voltage drops to 10.5 Volts.
OVER VOLTAGE PROTECTION
The inverter will automatically shut down when the input voltage exceeds 15.3 Volts DC. Input voltage
exceeding 16 Volts could damage the inverter.
OVERLOAD PROTECTION
The inverter will automatically shut down when the continuous draw exceeds rated Watts.
SHORT CIRCUIT PROTECTION
The inverter will shut down. remove the short circuit and restart inverter.
EARTH FAULT PROTECTION
This inverter complies with the standard current leakage allowance. When large current leakage to earth
terminal occurs, the protection circuit activates and shuts down the inverter, which prevents electric shock to
humans. Turn off the inverter, unplug the fault AC appliance and then turn oN is the only way to restart it.
The 1000, 1500 and 2000 W models are provided with a GfCI that will trip in case of any leakage on the load
side. The GfCI will be required to be reset
LOW INPUT VOLTAGE ALARM
An alarm will sound when the voltage at the input terminals of the inverter drops to 11.0 Volts. This is an
indication that either the battery terminal voltage has dropped due to its discharged condition and needs to
be re-charged 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 10.5 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 page 14.
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.
