ELECTRICAL HAZARDS

FIRE HAZARDS

The generator covered by this manual produces dangerous electrical voltages that can cause fatal electrical shock. Avoid contact with bare wires, ter- minals, connections, etc., while the unit is running. Ensure all appropriate covers, guards, and barri- ers are in place before operating the generator. If work must be done around an operating unit, stand on an insulated, dry surface to reduce shock hazard.

Do not handle any kind of electrical device while standing in water, while barefoot, or while hands or feet are wet. DANGEROUS ELECTRICAL SHOCK MAY RESULT.

During installation onto the vehicle, properly ground (bond) the generator either by solid mount- ing to the vehicle frame or chassis, or by means of an approved bonding conductor. DO NOT connect the bonding conductor to any generator part that might be removed or disassembled during routine maintenance. If the grounding conductor must be replaced, use only a flexible conductor that is of No. 8 American Wire Gauge (AWG) copper wire minimum.

If the vehicle electrical circuits can be powered by any other source of electricity (such as, a “dockside” power receptacle), there must be no possibility of connecting the different power sources to the vehi- cle’s circuits at the same time. The dockside (utility) power source must be positively isolated from the vehicle’s circuits whenever the generator is operat- ing. Failure to isolate the vehicle’s circuits from the dockside power supply when the generator is run- ning may result in damage to the generator or in serious injury or death to dockside (utility) power workers due to backfeed of electrical energy.

In case of an accident caused by electric shock, immediately shut down the source of electrical power. If this is not possible, attempt to free the victim from the live conductor. AVOID DIRECT CONTACT WITH THE VICTIM. Use a noncon- ducting implement, such as, a rope or board, to free the victim from the live conductor. If the vic- tim is unconscious, apply first aid, and get immediate medical help.

Never wear jewelry when working on this equip- ment. Jewelry can conduct electricity, resulting in electric shock, or may get caught in moving com- ponents, causing injury.

For fire safety, the generator must be installed and maintained properly. Installation always must comply with applicable codes, standards, laws, and regulations. Adhere strictly to local, state and national electrical and building codes. Comply with regulations the Occupational Safety and Health Administration (OSHA) has estab- lished. Also, ensure that the generator is installed in accordance with the manufacturer’s instructions and recommendations. Following proper installation, do nothing that might alter a safe installation and render the unit in noncom- pliance with the aforementioned codes, stan- dards, laws, and regulations.

Keep a fire extinguisher in the vehicle at all times. Extinguishers rated “ABC” by the National Fire Protection Association are appropriate for use on the recreational vehicle generator electrical system. Keep the extinguisher properly charged, and be familiar with its use. If there are any questions per- taining to fire extinguishers, consult the local fire department.

Manual background EXPLOSION HAZARDS Manual background

Do not smoke around the generator. Wipe up any fuel or oil spills immediately. Ensure that no com- bustible materials are left in the generator com- partment, or on or near the generator, as FIRE or EXPLOSION may result. Keep the area surround- ing the generator clean and free from debris.

All fuel types are potentially FLAMMABLE and/or EXPLOSIVE and should be handled with care. Comply with all laws regulating the storage and han- dling of fuels.

Fuel supply lines must be properly installed, purged and leak-tested according to applicable fuel-gas codes, before placing this equipment into service. There must be no possibility of fuel vapors enter- ing the vehicle interior.

It is required to install an approved, flexible, non- conductive fuel line between the generator fuel con- nection point and the rigid fuel lines.
