ELECTRICAL HAZARDS

• All generators covered by this manual produce dangerous
electrical voltages and can cause fatal electrical shock. Utility
power delivers extremely high and dangerous voltages to the
transfer switch as does the standby generator when it is in
operation. Avoid contact with bare wires, terminals, connec-
tions, etc., while the unit is running. Ensure all appropriate
covers, guards and barriers are in place, secured and/or locked
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 stand-
ing in water, while barefoot, or while hands or feet are wet.
DANGEROUS ELECTRICAL SHOCK MAY RESULT.
• The National Electrical Code (NEC) requires the frame and external
electrically conductive parts of the generator to be connected to
an approved earth ground. Local electrical codes also may require
proper grounding of the generator electrical system.
• After installing this home standby electrical system, the genera-
tor may crank and start at any time without warning. When this
occurs, load circuits are transferred to the STANDBY (genera-
tor) power source. To prevent possible injury if such a start and
transfer occur, always set the generator's AUTO/OFF/MANUAL
switch to its OFF position before working on equipment and
remove the 7.5A fuse from the generator control panel.
• In case of 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 nonconducting implement,
such as a dry rope or board, to free the victim from the live
conductor. If the victim is unconscious, apply first aid and get
immediate medical help.
• Never wear jewelry when working on this equipment. Jewelry
can conduct electricity resulting in electric shock, or may get
caught in moving components causing injury.
FIRE HAZARDS
• For fire safety, the generator must be installed and maintained
properly. Installation must always 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 established. Also, ensure that the
generator is installed in accordance with the manufacturer's
instructions and recommendations. Following proper installa-
tion, do nothing that might alter a safe installation and render
the unit in noncompliance with the aforementioned codes,
standards, laws and regulations.
• Keep a fire extinguisher near the generator at all times.
Extinguishers rated "ABC" by the National Fire Protection
Association are appropriate for use on the standby electric
system. Keep the extinguisher properly charged and be familiar
with its use. Consult the local fire department with any ques-
tions pertaining to fire extinguishers.

EXPLOSION HAZARDS

• Do not smoke around the generator. Wipe up any fuel or oil
spills immediately. Ensure that no combustible materials are left
in the generator compartment, or on or near the generator, as
FIRE or EXPLOSION may result. Keep the area surrounding the
generator clean and free from debris.
• Gaseous fluids such as natural gas and liquid propane (LP)
gas are extremely EXPLOSIVE. Install the fuel supply system
according to applicable fuel-gas codes. Before placing the
home standby electric system into service, fuel system lines
must be properly purged and leak tested according to applica-
ble code. After installation, inspect the fuel system periodically
for leaks. No leakage is permitted.
