Safety Rules - Generac Power Systems Automatic Transfer Switch Owner's Manual

SAFETY RULES

SAVE THESE INSTRUCTIONS! Read the fol-

lowing 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 elec-
tric 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.
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, therefore, not all-inclusive. If
using a procedure, work method or operating technique the manu-
facturer does not specifically recommend, ensure that it is safe for
others. Also make sure the procedure, work method or operating
technique chosen 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 care-
lessly. Observe them carefully. Their definitions are as follows:
After this heading, read instructions that, if not
strictly complied with, will result in serious
personal injury, including death.
After this heading, read instructions that, if not
strictly complied with, could result in serious
personal injury, including death.
After this heading, read instructions that, if not
strictly complied with, might result in minor or
moderate injury.
After this heading, read instructions that, if not strictly complied
with, may result in damage to equipment and/or property.
These safety warnings cannot eliminate the hazards that they
indicate. Common sense and strict compliance with the special
instructions while performing the service are essential to prevent-
ing accidents.
NOTE:
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.
    T his symbol points out potential explosion
hazard.

This symbol points out potential fire hazard.
    T his 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 personal injury, or damage to equipment and/
or personal 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 possibly 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 ser-
vice 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 stand-
ing in water, while barefoot, or while hands or feet are wet.
DANGEROUS ELECTRICAL SHOCK MAY RESULT.
• Remove all jewelry (such as rings, watches, bracelets, etc.)
before working on this equipment.
• If work must be done on this equipment while standing on metal
or concrete, place insulative mats over a dry wood platform.
Work on this equipment only while standing on such insulative
mats.
For authorized service,
reference the dealer locator
number found inside the
generator owner's manual.
