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(s) when it is in
operation. Avoid contact with bare wires, termi-
nals, connections, etc., while the unit is running.
Ensure all appropriate covers, guards and barriers
are in place before operating the generator(s). If
working 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(s) to be connected to an approved
earth ground and/or grounding rods. Local electri-
cal codes also may require proper grounding of the
generator(s) electrical system.
• After installing this standby electrical system, the
generator(s) may crank and start at any time with-
out 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 15A
fuse in front 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 imple-
ment, such as a rope or board, to free the victim
from the live conductor. If the victim is uncon-
scious, 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(s) 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(s) 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(s) 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. If there are any questions pertaining to fire
extinguishers, consult the local fire department.
EXPLOSION HAZARDS
• Do not smoke around the generator(s). Wipe up
any fuel or oil spills immediately. Ensure that no
combustible materials are left in the generator(s)
compartment, or on or near the generator(s), as
FIRE or EXPLOSION may result. Keep the area
surrounding the generator(s) clean and free from
debris.
