WARNING!
Before installing and using the Inverter, you need to read
the following safety information carefully.
1. Important Safety Information
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.
Over heating 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 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, or joints, fittings,
or other connection between components of the fuel system.
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 flood eye 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 of 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 the like to metal, causing a severe burn
