1. Important 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 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.

WARNING!

Before using the Inverter, read and

save the safety instructions.
