Safety Information
General
zWear proper protective equipment and use insulated tools during installation and operation. Do not
wear jewelry or other metal objects when working on or around the devices.
zKeep the devices out of the reach of children.
zDo not dispose of the devices as household waste. Comply with local, state, and federal laws and
regulations and use recycling channels as required.
zIn case of fire, put out the fire with a FM-200 or CO2fire extinguisher.
zInstalling the devices improperly on a boat may cause damage to components of the boat. Have the
devices installed by a qualified electrician.
zDo not expose the devices to flammable or harsh chemicals or vapors.
zClean the devices regularly.
zDo not puncture, drop, crush, penetrate, shake, strike, or step on the devices.
zDo not open, disassemble, repair, tamper with, or modify the devices.
zConnect the negative prior to the positive terminal when connecting any device.
Battery Safety
zDo not use batteries if there is any damage.
zDo not touch the exposed electrolyte or powder if the battery is damaged.
zRisk of explosion! Never install the battery charger and inverter charger in a sealed enclosure with
flooded batteries! Do not install the battery charger, and inverter charger in a confined area where
battery gases can accumulate.
zPrior to installing the devices, ensure all battery groups are installed properly.
Battery Charger, and Inverter Charger Safety
zInstall the devices indoors on a vertical surface - protected from direct sunlight, high temperatures,
and water. Make sure there is good ventilation.
zKeep the devices away from heating equipment.
zDo not insert foreign objects into the devices.
zConfirm the polarities of the devices before connection. A reverse polarity contact can result in
damage to the devices, thus voiding the warranty.
zDo not touch the connector contacts while the devices are in operation.
zDisconnect all connectors from the devices before maintenance or cleaning.
zEnsure the inverter charger is firmly grounded to a building, vehicle, or earth grounded. Keep the
inverter charger away from EMI receptors such as TVs, radios, and other audio/visual electronics to
prevent damage / interference to the equipment.
Solar Panel Safety
zDo not install the solar panel on a surface constructed from combustible material.
zDo not expose the solar panel to direct flame or heat sources.
zKeep the solar panel away from explosives and corrosive substances.
zDo not step, walk, stand, or jump on the solar panel. Localized heavy loads may cause damage to the
solar cells, which will ultimately compromise the performance of the solar panel.
zDo not band the solar panel. Bending the solar panel will cause damage to the cells and affect panel
performance.
zDo not immerse the solar panel in water.
