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 uti-
lized 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 person-
nel to special instruction about a particular operation
that may be hazardous if performed incorrectly or
carelessly. Observe them carefully. The definitions
are as follows:
DANGER
After this heading, read instructions that, if not
strictly complied with, will result in personal injury
or property damage.
After this heading, read instructions that, if not
strictly complied with, may result in personal inju-
ry 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 infor-
mation that, if not followed, could endanger
personal safety and/or property of 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 strictly
to local, state and national electrical and building
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 sys-
tem 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.
