Generac 4678-1 - Manual (Page 2)

Generac ® Power Systems, Inc.
Generac cannot possibly anticipate every possible cir
cumstance that might involve a hazard. The warn-
ings in this manual, and on tags and decals
affixed to the unit are, therefore, not all-inclusive. If
you use a procedure, work method or operating tech-
nique Generac does not specifically recommend, you
must satisfy yourself that it is safe for you and others.
You also must make sure the procedure, work
method or operating technique that you choose does
not render the transfer switch unsafe.
Throughout this publication, and on tags and
decals affixed to the generator, DANGER, WARNING,
CAUTION and NOTE blocks are used to alert you to
special instruction about a particular operation that
may be hazardous if performed incorrectly or care-
lessly. Observe them carefully. Their definitions are
as follows:
After this heading, you can read instructions that,
if not strictly complied with, will result in personal
injury or property damage.
After this heading, you can read instructions that,
if not strictly complied with, may result in personal
injury or property damage.
After this heading, you can read instructions that, if
not strictly complied with, could result in damage to
equipment and/or property.
NOTE:
After this heading, you can read explanatory
statements that require special emphasis.
These safety warnings cannot eliminate the hazards
that they indicate. Common sense and strict compli-
ance with the special instructions while performing the
service are essential to preventing accidents.
Four commonly used safety symbols accompany the
DANGER, WARNING and CAUTION blocks. The type
of information each indicates follows:
This symbol points out important safety informa-
tion that, if not followed, could endanger personal
safety and/or property of you and others.
This symbol points out potential explosion hazard.
This symbol points out potential fire hazard.
This symbol points out potential electrical shock
hazard.
GENERAL HAZARDS
• Any AC generator that is used for backup power if
a NORMAL (utility) power source failure occurs,
must be isolated from the NORMAL (utility) power
source by means of an approved transfer switch.
Failure to properly isolate the NORMAL and
STANDBY power sources from each other may
result in injury or death to electric utility workers,
due to backfeed of electrical energy.
• Improper or unauthorized installation, operation,
service or repair of the equipment is extremely
dangerous and may result in death, serious per-
sonal injury, or damage to equipment and/or per-
sonal property.
• Extremely high and dangerous power voltages are
present inside an installed transfer switch. Any
contact with high voltage terminals, contacts or
wires will result in extremely hazardous, and pos-
sibly LETHAL, electric shock. DO NOT WORK ON
THE TRANSFER SWITCH UNTIL ALL POWER
VOLTAGE SUPPLIES TO THE SWITCH HAVE
BEEN POSITIVELY TURNED OFF.
• Competent, qualified personnel should install,
operate and service this equipment. Adhere strict-
ly to local, state and national electrical and build-
ing codes. When using this equipment, comply
with regulations the National Electrical Code
(NEC) and Occupational Safety and Health
Administration (OSHA) have established.
• Never handle any kind of electrical device while
standing in water, while barefoot, or while hands
or feet are wet. DANGEROUS ELECTRICAL
SHOCK MAY RESULT.

Important Safety Instructions
Read the following information carefully before attempting to install, operate or service this
equipment. Also read the instructions and information on tags, decals, and labels that may
be affixed to the transfer switch. Replace any decal or label that is no longer legible.
DANGER! Connection of a generator to an electrical system normally supplied by an elec-
tric utility shall be by means of a double throw switch so as to isolate the electric system
from utility distribution system when the generator is operating (NEC 701). Failure to iso-
late electric system by these means results in damage to generator and may result in injury
or death to utility workers due to backfeed of electrical energy.
