 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, 
connections, 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 cir-
cuits 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 7.5A 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 regula-
tions.

• 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.

 EXPLOSION 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 pro-

pane (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, inspect the fuel 
system periodically for leaks. No leakage is permit-
ted.
