1. Important Safety Instructions

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 result.

1-1-2. To avoid a risk of fire and electronic shock, make sure that existing

wiring is in good electrical condition and not undersized.

Do not operate the Inverter with damaged or substandard Wiring.

1-1-3. There are some components in the inverter can cause arcs and sparks.

To prevent from fire or explosion, do not put batteries, flammable

materials, or anything should be ignition–protected around the inverter.

1-2. Precautions When Working with Batteries

1-2-1. If battery acid contacts skin or clothing, you shall wash it out with soap

and water immediately. If battery acid contacts your eyes, you shall

wash it out with cold running water for at least 20 minutes and get

medical attention immediately.

1-2-2. Never smoke or make a spark or flame in the vicinity of the battery or

the engine.

1-2-3. Do not drop a metal tool on the battery. The resulting spark or

short-circuit on the battery of other electrical part may cause an

explosion.

1-2-4. Remove personal metal items such as rings, bracelets, necklaces,

and watches when operating with a lead-acid batteries.

Doing so may cause short circuit and very high temperature, which can

melt metal items and even burn you.
