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.
NOTE:
After this heading, read instructions that, if not strictly complied
with, may result in damage to equipment and/or property.
