Understanding the LED indicators
‘Power’ indicator: Indicator turn on indicate unit is ON.
‘Fault’ indicator: Indicator turns on indicate fault was detected. Unit has shutdown. To reset unit,
remove the fault condition and reset unit by using the toggle switch and turn
unit off and on again.
Understanding the fan operation
The fan on the unit will automatically turns on when it sense the internal temperature of the unit reach
to its preset level.
AC Load on Power Inverter
Although the Power Inverter can provide high surge power up to two times the rated output power,
some appliances may still trigger on the inverter protection system. A higher power inverter is required
for those appliances.
For 38204 , with modified sine wave output, some appliances like speed controllers found in some
fans, power tools and some power tools’ AC charger may not like the modified sine wave generated
by the inverter, those appliances may not work or may be damaged if they are connected to the
inverter. If you are unsure about powering any device with the inverter, contact the manufacturer of the
device.
Estimate Run time on Load
Following run time is an estimate based on using a 12V-120AH battery bank for reference. Actual run
time may vary. those appliances may not work or may be damaged if they are.

maintenance, fire and flood.
Nature Power Inverters are Made in China.
Power Inverter DC Input Connection:
•
Connect one end of the negative DC input cable to the Power Inverter DC negative terminal
(black). Connect the other end of the negative DC input cable to the battery negative terminal.
• Make sure the Disconnect Switch is in the OFF position.
• Connect one end of the positive DC input cable to the Power Inverter DC positive terminal (red).
Connect the other end of the positive DC input cable to one of the terminal of the Disconnect
Switch.
• Connect a DC input cable between the other terminal of the Disconnect Switch and one side of
the terminal of thefuse holder.
• Connect a DC input cable between the other terminal of the fuse holder and the battery positive
terminal.
• Install the selected fuse to the fuse holder.
• Turn Disconnect Switch to ON position.
Connect unit using the Lighter plug cable:
CAUTION:
Due to the limitations of the 12V lighter plug socket in vehicles, the unit should be used
with the DC cable with lighter plug only to supply AC power to products that require 150W
(120VAC/1.3 A) or less. If the appliance requires more than 150W, use the optional DC cable
clips
for battery connection.
• Attach the red ring-type connector to the positive (+) DC terminal (red) on the power inverterand
connect the black ring type connector to the negative (-) DC terminal (black) on the Power inverter.
• Tighten the nut on each DC terminal.
• Insert the light plug of this cable to the fused 12V lighter plug socket.
• Unit is ready for use.
Connect unit using the Battery clips cable:
CAUTION:
Please be sure all the connections are tight before the use of the unit.
• Attach the red ring-type connector to the positive (+) DC terminal (red) on the power inverter and
connect the black ring type connector to the negative (-) DC terminal (black) on the Power inverter.
• Attach the negative (black) clip to the negative (-) battery terminal.
• Attach the positive (red) clip to the fuse or circuitry breaker of the 12V battery bank as indicated on
‘Typical Wiring block diagram of the Power Inverter’ on page 5.
• Unit is ready for use.
Testing the Power Inverter:
• Turn unit on by using the On/Off button on the unit. The ‘Power’ light turns on indicating the Nature
Power Inverter is ON. AC output is now available.
• Plug in a small AC load like a 25W table lamp or small appliance to the AC socket to verify AC is
available.
• The unit is successfully installed and functioning properly.
Test the GFCI monthly:
• Use the following instruction to perform a monthly test on the GFCI to ensure the GFCI is
functioning properly.
• Turn unit on and plug a small AC load (40W light bulbs) to the GFCI.
• Check the AC load is ON.
• Press ‘Test’ button and observe a click sound. Check AC load is turned off.
• Press ‘RESET’ button and check the AC load is back ON again.
WARNING:
RISK OF EQUIPMENT DAMAGE
• Do not plug surge-protected power bars into the unit’s 120 VAC outlets. The surge protected
components on the surge-protected power bar may not like the modified sine wave output
generate by the inverter.
• Do not connect an AC power source like utility power or generator to the unit 120 VAC outlets.
Turn ON and OFF the unit
• Toggle the On/Off switch to ‘ON’ position to turn unit ON.
• ‘Power’ indicator will turn green.
• 120 VAC Output is available at the AC output socket. (For 38304, 5V USB is also available.)
• Toggle the On/Off switch to ‘Off’ position to turn unit off. ‘Power’ indicator will turn off.
