- Do not expose the Inverter to rain, snow, spray, bilge or dust. To reduce risk of hazard, do not cover or obstruct the ventilation openings. Do not install the inverter in a zero-clearance compartment. Overheating may take place.
- To avoid a risk of fire and electric shock, please make sure that existing wiring is in good electrical condition; and that wire size is not undersized. Do not operate the Inverter with damaged or substandard wiring.
- This equipment contains components which can produce arcs or sparks.
- To prevent fire or explosion do not install in compartments containing batteries or flammable materials or in locations which require ignition protected equipment. This includes any space containing gasoline-powered machinery, fuel tanks, joints, fittings, or other connection between components of the fuel system.
- An over current protection at the time of installation shall be provided by others for the AC output circuit.
- Additional breakers suitable for 20 A branch circuit protection shall be provided for the GFCI receptacles.
PRECAUTIONS WHEN WORKING WITH BATTERIES
- If battery acid contacts skin or clothing, wash immediately with soap and water. If acid enters eye, immediately wash eyes with running cold water for at least 20 minutes and get medical attention immediately.
- Never smoke or allow a spark or flame in vicinity of battery or engine.
- Do not drop a metal tool on the battery. The resulting spark or short-circuit on the battery or other electrical part may cause an explosion.
- Remove personal metal items such as rings, bracelets, necklaces and watches when working with a lead-acid battery. A lead-acid battery produces a short-circuit current high enough to weld a ring or similar item to metal causing a severe burn.
INSTALLATION
The power inverter should be installed in a location that meets the following
requirements:
- Dry – Do not allow water to drip or splash on the inverter.
- Cool – Ambient air temperature should be between -20°C and 50°C, but the cooler the better.
- Safety – Do not install batteries in the compartment or other areas near flammable fumes such as fuel storage areas or engine compartments.
- Ventilated – Allow at least one feet of clearance around the Inverter for air flow. Ensure the ventilation shafts on the rear and bottom of the unit are not obstructed.
- Dust-free – Do not install the Inverter in dusty environments here dust, wood particles or other filings/shavings are present. The dust can be pulled into the unit when the cooling fan is in operation.
- Close to batteries – Avoid excessive cable lengths but do not install the inverter in the same compartment as batteries.
- Use the recommended wire lengths and sizes (refer to section 4.DC wiring connections).
- Do not mount the inverter where it is exposed to the gases produced by the battery. These gases are very corrosive and prolonged exposure will damage the inverter.
WARNING
Shock Hazard. Before proceeding further, carefully check that the inverter is
NOT connected to any batteries, and that all wiring is disconnected from any
electrical sources. Do not connect the output terminals of the inverter to an
incoming AC source.

WARNING
-
Make sure all the DC connections are tight (torque to 11 ft-lbs, 15 Nm Max.). Loose connections could overheat and result in a potential hazard.
-
The installation of a fuse must be on the positive cable. Failure to place a fuse on “+” cables running between the inverter and battery may cause damage to the inverter and will
void warranty. -
Also, only use high quality copper wire and keep the cable length short – maximum of three – six feet.
Do not place anything between battery cable lug and terminal surface. Assemble exactly as shown.
WARNING
During the first installation, a small spark is a normal phenomenon because
the internal capacitors charging. Do not be concerned.
DC INPUT TERMINALS
Connect DC input terminals to 12V / 24V / 48V battery or other power sources.
[ + ] represents positive, [ – ] represents negative. Reverse polarity
connection can blow the internal fuse and may damage the inverter permanently.

CAUTION!
- It is advised that all the electrical installation should conform to the local electrical codes and should be carried out by a certified technician. When the unit is feeding the internally inverted voltage, the current carrying conductors connected to the “L” and “N” terminals of the AC output will be isolated from the metal chassis of the inverter. Hence, during this condition, when the metal chassis of the inverter is connected to the earth ground, the “N” terminal of the AC output will not be grounded (bonded) to the earth ground. Under this condition, the “N” terminal of the AC output will not be a Neutral in the true sense. Do not touch this terminal as it will be at an elevated voltage (almost half the value the AC output voltage) with respect to the metal chassis / earth ground and may produce an electrical shock when touched!
- When the unit is transferring power from the AC input source, the grounding condition of the “N” terminal of the AC output will be the same as the condition of the “N” terminal of the AC input source. If the AC input source is the power supplied from the utility, the “N” terminal would be a Neutral in the true sense. It will normally be bonded to the earth ground and will read almost 0 V with respect to the earth ground. In this case, touching this terminal will not be a shock hazard.
NOTE – In case the load current over the outlet rated current, please use the hard wire terminal next to the outlets.
WARNING: When using full power, it is recommended to use the wiring terminal.
