Generac Power Systems, Inc., hereafter referred to as
the “manufacturer”, cannot anticipate every possible
circumstance 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 using a
procedure, work method or operating technique the
manufacturer does not specifically recommend,
ensure that it is safe for others. Also make sure the
procedure, work method or operating technique cho-
sen 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 per-
sonnel to special instructions about a particular
operation that may be hazardous if performed incor-
rectly or carelessly. Observe them carefully. Their def-
initions are as follows:
After this heading, read instructions that, if not
strictly complied with, will result in personal
injury, including death, or property damage.
After this heading, read instructions that, if not
strictly complied with, may result in personal injury
or property damage.
After this heading, read instructions that, if not
strictly complied with, could result in damage to
equipment and/or property.
NOTE:
After this heading, 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.
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), CSA Standard; C22.1 Canadian Electric
Code 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
SAVE THESE 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 electric
utility shall be by means of suitable transfer equipment so as to isolate the electric system
from utility distribution system when the generator is operating (Article 701 Legally Required
Standby Systems or Article 702 Optional Standby Systems, as applicable). Failure to isolate
electric system by these means may result in damage to generator and may result in injury
or death to utility workers due to backfeed of electrical energy.
