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.
The manufacturer cannot anticipate every possible
circumstance that might involve a hazard. The
warnings in this manual, and on tags and decals
affixed to the unit are not all-inclusive. If using a
procedure, work method or operating technique the
manufacturer does not specifically recommend,
ensure that it is safe. Also make sure the procedure,
work method or operating technique used 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
personnel to special instructions about a particular
operation that may be hazardous if performed
incorrectly or carelessly. Observe them carefully.
Their definitions are as follows:
NOTE:
Notes contain additional information important to a
procedure and will be found within the regular text of

These safety warnings cannot eliminate the hazards
that they indicate. Common sense and strict
compliance with the special instructions while
performing the action or service are essential to
preventing accidents.
1.2 — 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
personal injury, or damage to equipment and/or
personal property.
• Extremely high power and dangerous voltages are
present inside an installed transfer switch. Any
contact with high voltage terminals, contacts or
wires can result in LETHAL electric shock, while
arc flash can cause blindness and severe burns.
DO NOT WORK ON THE TRANSFER SWITCH
UNTIL ALL POWER 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

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.
