Please note that some chargers for small nickel-cadmium batteries can be damaged if connected to the
EW-800USB inverter.
DO NOT USE THE INVERTER WITH THE FOLLOWING APPLIANCES:
Small battery-operated appliances like rechargeable flashlights, some rechargeable shavers, and night lights that
are plugged directly into an AC receptacle to recharge.
Battery chargers used in hand power tools. These chargers display a warning label stating that dangerous
voltages are present at the charger battery terminals.
Interference may occur when supplying power to audio system, radio or TV.
IMPORTANT SAFETY INFORMATION
Misusing or incorrectly connecting the EW-800USB inverter may damage the equipment or create hazardous conditions for users.
Read the following safety instructions and pay special attention to all Caution and Warning statements in the guide.
Danger and Warnings identify conditions that may result in personal injury or loss of life.
Cautions identify conditions or practices that may damage the unit or other equipment.
ELECTRICAL SHOCK HAZARD
Keep children away from the EW-800USB inverter. The inverter generates the same potentially lethal AC power as
a normal household wall outlet.
Do not use the EW-800USB inverter in the presence of flammable fumes or gases, such as in the bilge of a
gasoline powered boat, or near propane tanks. Do not use the EW-800USB inverter in an enclosure containing
automotive-type, lead-acid batteries. These batteries, unlike sealed batteries, vent explosive hydrogen gas, which
can be ignited by sparks from electrical connections.
Failure to follow these instructions will result in death or serious injury.
HEATED SURFACE HAZARD
Batteries generate explosive gases during normal operation. Read this guide and follow the instructions exactly
before installing or using your inverter.
This equipment contains components that tend to produce arcs or sparks. To prevent fire or explosion, do not
install the inverter in compartments containing batteries or flammable materials, or in locations that require
ignition-protected equipment. These locations include any space containing gasoline-powered machinery, fuel
tanks, as well as joints, fittings, or other connections between components of the fuel system.
Failure to follow these instructions can result in death or serious injury.
EXPLOSION AND FIRE HAZARD
Follow all instructions published by the battery manufacturer and the manufacturer of the equipment in which
the battery is installed.
Make sure the area around the battery is well ventilated.
Never smoke or allow a spark or flame near the engine or batteries.
Use caution to reduce the risk of dropping a metal tool on the battery, which could spark or short circuit the
battery or other electrical parts and could cause an explosion.
Remove metal items like rings, bracelets, and watches when working with lead-acid batteries. Lead-acid batteries
produce a short circuit current high enough to weld a ring or the like to metal, and thus cause a severe burn.
If you need to remove a battery, always remove the ground terminal from the battery first. Make sure all accesso-
ries are off so you don’t cause a spark.
Failure to follow these instructions can result in death or serious injury.
