1.1 GENERATOR INSTALLATION
This equipment is a liquid-cooled, engine-driven generator set.
The generator is designed to supply electrical power that operates
critical electrical loads during utility power failure. The unit has
been factory-installed in a weather resistant, all metal enclosure
and is intended for outdoor installation only.

If this generator is used to power electrical
load circuits normally powered by a utility
power source, it is required by code to install
a transfer switch. The transfer switch must
effectively isolate the electric system from the
utility distribution system when the generator
is operating (NEC 701). Failure to isolate an
electrical system by such means results in
damage to the generator and may also result
in injury or even death to utility power workers
due to backfeed of electrical energy.
1.2 BEFORE INSTALLATION
NOTE:
Contact the local inspector or City Hall to make sure you are
aware of all federal, state and local codes that could impact the
installation. Secure all required permits before starting the job.
Before installing this equipment, check the ratings of both the
generator and the transfer switch. Read “Emergency Isolation
Method” and “Total Circuit Isolation Method”.
The generator’s rated wattage/amperage capacity must be
adequate to handle all electrical loads that the unit will power. The
critical (essential) loads may need to be grouped together and
wired into a separate “emergency” distribution panel.

Connecting this generator to an electrical
system normally supplied by an electric utility
shall be by means of a transfer switch, so as
to isolate the electric system from the utility
distribution system when the generator is
operating. Failure to isolate the electric system
by these means will result in damage to the
generator and may also result in injury or death
to utility workers due to backfeed of electrical
energy.

If an open bottom is used, the engine-generator
is to be installed over non-combustible
materials and should be located such that
combustible materials are not capable of
accumulating under the generator set.
Only authorized dealers or qualified, competent installation
contractors or electricians thoroughly familiar with applicable
codes, standards and regulations should install this standby
electric power system. The installation must comply strictly with
all codes, standards and regulations pertaining to the installation.

After the system has been installed, do
nothing that might render the installation in
noncompliance with such codes, standards and
regulations.
1.2.1 NFPA STANDARDS
Applicable national, state, or local laws, codes, and regulations
pertaining to the installation of engine-generator power systems
must be strictly complied with. Always use the current acceptable
