Carrier Circuits 50A 240V, Installation Manual

• Never use the generator or any of its parts as a step. Stepping on the unit
can stress and break parts, and may result in dangerous operating
conditions from leaking exhaust gases, fuel leakage, oil leakage, etc.
ELECTRICAL HAZARD
• 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, connections, etc., while the unit is running. Ensure all
appropriate covers, guards and barriers are in place before operating
the generator. If you must work 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 the home standby electrical system has been installed it will be
capable of cranking and starting at any time while in the “Auto” mode.
When the unit starts in “Auto” the load circuits are transferred to the
STANDBY (generator) power source. To prevent possible injury when working
on the system
always set the generator’s Auto/Off/Manual switch to its
“OFF”, remove control panel fuses and disconnect the starting battery.
• 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 non-conducting implement, such as a 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 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 installation, 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. If you have any question pertaining
to fire extinguishers, consult your local fire department.
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 applicable code. After installation, you must inspect
the fuel system periodically for leaks. No leakage is permitted.

All CARRIER air-cooled generators are listed to applicable U.S. and
Canadian safety standards by Underwriters Laboratories Inc. UL
2200 covers safety standards for engine generator assemblies and
UL 1008 covers standards for transfer switches. UL Listing is your
only assurance of local building inspection approval, safety and
certified kW power ratings.
