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 i
