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 opera-
tion. Avoid contact with bare wires, terminals, con-
nections, etc., while the unit is running. Ensure all
appropriate covers, guards and barriers 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.
• 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 sys-
tem, the generator may crank and start at any time
without warning. When this occurs, load circuits
are transferred to the STANDBY (GENERATOR)
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 5A
and 15A fuses from the generator control panel.
• In case of accident caused by electric shock, imme-
diately 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 equip-
ment. Jewelry can conduct electricity resulting in
electric shock, or may get caught in moving com-
ponents causing injury.
FIRE HAZARDS
• 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 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 regu-
lations.
• 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 extin-
guisher properly charged and be familiar with its
use. Consult the local fire department with any
questions pertaining to fire extinguishers.
EXPL
OSION HAZARDS
• 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.
• Gaseous fluids such as natural gas and liquid
propane (LP) gas are extremely EXPLOSIVE.
Install the fuel supply system according to applica-
ble fuel-gas codes. Before placing the home stand-
by electric system into service, fuel system lines
must be properly purged and leak tested according
to applicable code. After installation, inspect the
fuel system periodically for leaks. No leakage is
permitted.
