INSTALLATION RULES

This equipment is a liquid-cooled, generator set. The generator is
designed to supply electrical power that operates critical electrical
loads during utility power failure.

If this generator is used to power electrical
load circuits normally powered by a util-
ity 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.

BEFORE INSTALLATION

Before installing this equipment, check the ratings of both the gen-
erator and the transfer switch. Read "Emergency Isolation Method"
and "Total Circuit Isolation Method" Paragraph.
The generator's rated wattage/amperage capacity must be ade-
quate 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 Stationary Emergency
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 distribu-
tion system when the Stationary Emergency
Generator is operating. Failure to isolate the
electric system by these means will result
in damage to the Stationary Emergency
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 Stationary
Emergency Generator is to be installed over
non-combustible materials and should be
located such that combustible materials
are not capable of accumulating under the
Stationary Emergency Generator set.
Only qualified, competent installation contractors or electricians
thoroughly familiar with applicable codes, standards and regula-
tions should install this stationary emergency electric power sys-
tem. The installation must comply strictly with all codes, standards
and regulations pertaining to the installation.
Installation
After the system has been installed, do noth-
ing that might render the installation in non-
compliance with such codes, standards and
regulations.
