WARNING: Fire and/or chemical burn hazard
• Do not cover or obstruct any air vent openings and/or install in a zero-clearance compartment.
WARNING: Failure to follow these instructions can result in death or injury.
The Nature Power Inverter package includes the items list below.
• Power Inverter base unit
• Owner’s manual
• DC Input cable accessories
WARNING:
Nature Power recommends that all wiring be done by a certified technician or electrician
to ensure adherence to the applicable electrical safety wiring regulations and installation codes.
Failure to follow these instructions can damage the unit and could also result in personal injury or
loss of life.
CAUTION: Before beginning your power inverter Installation, please consider the following:
• The Nature Power Inverter base unit should be used or stored in an indoor area away from direct
sunlight, heat, moisture or conductive contaminants.
• When placing the unit, allow a minimum of three inches of space around the unit for optimal
ventilation.
12V Battery Bank:
• The use of deep cycle battery is highly recommended for power inverter application.
• For battery size, you need to identify how much you will be using them between charges. Nature
Power recommends you purchase as much battery capacity as possible. See more on Battery Run
time and Load in Section 4.
Fuse or Circuit Breaker:
• DC-rated fuse or DC-rated circuit breaker connected along the DC positive line is required.
•
Select a fuse or circuit breaker with a minimum of 60 ADC.
•
Based on the size of the battery bank chosen on the 12V Battery Bank above, determine the
overall short circuit current rating of the battery bank from the battery manufacturer. The fuse or
circuit breaker chosen has to be able to withstand the short circuit current that may be generated
by the battery bank.
Disconnect Switch:
•
Select a Disconnect Switch with the same or higher the rating of the selected fuse or circuit
breaker from the above.
• The Disconnect Switch is used to disconnect the DC power between the power inverter and the
battery bank during service, maintenance or trouble shooting.
DC Input Cable:
•
Use of low resistance wire is required for all the DC connections between the inverter and the
battery bank.
•
Uses minimum #10 AWG wire with maximum cable length of 5 feet.
Installing the Power Inverter System
WARNING:
Electrical Shock Hazard
The unit ‘On/Off’ switch does not disconnect the DC power from the battery. Use the DC Disconnect
Switch or disconnect the DC input cables connection to disconnect the DC power from the battery
before working on any circuits connected to the unit. Failure to follow these instructions can result in
death or serious injury.
CAUTION:
Reverse the DC Input terminal will damage the unit and cannot be repaired. Damage
caused by reverse polarity connection is not covered by the warranty.
Power Inverter Installation (38304 only):
• Choose an appropriate mounting location.
• For indoor use, the orientation of the unit can be mounted in any direction except with the DC
Input panel facing downwards.
• For RV installation, the unit has to be mounted flat on horizontal surface.
• Use mounting template below to mark the positions of the mounting screws.
• Drill the 4 mounting holes and place the inverter in position and fasten the inverter to the mounting
surface.

• When working with electrical equipment or lead acid batteries, have someone nearby in case of an
emergency.
• Study and follow all the battery manufacturer’s specific precautions when installing, using and servicing the
battery connected to the inverter.
• Wear eye protection and gloves.
• Avoid touching your eyes while using this unit.
• Keep fresh water and soap on hand in the event battery acid comes in contact with eyes. If this occurs,
cleanse right away with soap and water for a minimum of 15 minutes and seek medical attention.
• Batteries produce explosive gases. DO NOT smoke or have an open spark or fire near the system.
• Keep unit away from moist or damp areas.
• Avoid dropping any metal tool or object on the battery. Doing so could create a spark or short circuit which
goes through the battery or another electrical tool that may create an explosion.
WARNING: Shock Hazard. Keep away from children!
•Avoid moisture. Never expose unit to snow, water etc.
• Unit provides 120 VAC; treat AC output sockets the same as regular wall AC sockets at home.
WARNING: Explosion hazard!
• DO NOT use the Nature Power Inverter in the vicinity of flammable fumes or gases (such as
propane tanks or large engines).
• AVOID covering the ventilation openings. Always operate unit in an open area.
LIMITATIONS ON USE
•Do not use in connection with life support systems or other medical equipment or devices.
