1. Important Safety Information

WARNING!

Before using the inverter, read and save the safety instructions.

1-1. General Safety Precautions

1-1-1. 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.

1-1-2. 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.

1-1-3. 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.

1-1-4. An over current protection at the time of installation shall be provided by

others for the AC output circuit.

1-1-5. Additional breakers suitable for 20 A branch circuit protection shall be

provided for the GFCI receptacles.

1-2. Precautions When Working with Batteries

1-2-1. 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.

1-2-2. Never smoke or allow a spark or flame in vicinity of battery or engine.

1-2-3. 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.

1-2-4. 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.

1-3. 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 and 50 , but he cooler

the better.

Safety Do not install batteries in the compartment or other areas here flammable

fumes existence 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.
