Generac Power Systems RTS User's & Technical Manual page 2

 SAVE THESE INSTRUCTIONS - This manual contains important instructions that should be followed
during installation and maintenance of the generator and batteries.

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.
Generac Power Systems, Inc., hereafter referred to as the "manu-
facturer", 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:
DANGER
After this heading, read instructions that, if not
strictly complied with, will result in personal inju-
ry, including without limitation, death, 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.
After this heading, read explanatory statements that require
special emphasis.
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.
IMPORTANT SAFETY INSTRUCTIONS
NOTE:
Four commonly used safety symbols accompany the DANGER,
WARNING and CAUTION blocks. The type of information each
indicates follows:

tion that, if not followed, could endanger per-
sonal safety and/or property.

This symbol points out potential explosion
hazard.
 This symbol points out potential fire 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 ter-
minals, 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.
• Only 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.
