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 elec-
trical 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 gen-
erator is operating (Article 701 Legally Required
Standby Systems or Article 702 Optional
Standby Systems, as applicable). Failure to iso-
late 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.
