See Figure 2-8. The 2-pole circuit breaker (generator
disconnect) (A) is rated according to relevant
specifications.
Figure 2-8. Generator Main Line Circuit Breaker
The breaker can be locked in the OFF (OPEN) position
for security during maintenance or transfer switch
service. Use an appropriately-sized padlock (not
included) with a shackle long enough to pass through
both lock tabs (B).
NOTE: DO NOT leave the breaker disconnect locked in
the open (OFF) position during normal generator
operation. Leaving the breaker in the open position will
prevent the transfer of power to the generator from the
transfer equipment during normal generator operation.

Auxiliary Shutdown Switch
All generators are equipped with an external means of
shutting down the generator which complies with the
latest NEC code requirement. The primary generator
shutdown sequence is described in Control Panel Start-
Up/Testing.
See Figure 2-10. An auxiliary shutdown switch is
provided on the exterior of the generator back panel. This
switch shuts down the generator and disables restarts.
Figure 2-10. Auxiliary Shutdown Switch (all models)
NOTE: Whenever possible, perform the primary
shutdown procedure before disabling the generator with
the auxiliary shutdown switch.
See Figure 2-11. 20 kW generators also have an
auxiliary shutdown switch located inside the generator.
Figure 2-11. Auxiliary Shutdown Switch (20 kW)
The generator will not start if either switch is OPEN (O). The
controller displays an “Auxiliary Shutdown” alarm, and the
red LED “Alarm” light illuminates until the switch or switches
are CLOSED (I) and the alarm is cleared by pressing OFF
mode button, and then ENTER. Once cleared, the
generator can be placed back in AUTO or MANUAL.
CAUTION
(000399)
Equipment Damage. The auxiliary shutdown switch is
not to be used to power down the unit under normal
operating circumstances. Doing so will result in
equipment damage.

Site Selection and Preparation
14 Installation Guidelines for 60 Hz Air-Cooled Generators
See Figure 3-1. Install the generator set, in its protective
enclosure, outdoors where adequate cooling and
ventilating air is always available. Consider these factors:
•The installation of the generator must comply
strictly with ICC IFGC, NFPA 37, NFPA 54, NFPA
58, and NFPA 70 standards.
•Install the unit where air inlet and outlet openings
will not become obstructed by leaves, grass, snow,
etc. If prevailing winds will cause blowing or
drifting, consider using a windbreak to protect the
unit.
•Install the generator on high ground where water
levels will not rise and endanger it. This unit should
not operate in, or be subjected to, standing water.
•Allow sufficient room on all sides of the generator
for maintenance and servicing. This unit must be
installed in accordance with any local, state, or
national codes for minimum distances from other
structures.
•Clearance from the ends and front of the generator
must be 3 ft (0.91 m). This includes shrubs,
bushes, and trees. Clearance from the back of the
generator must be a minimum of 18 in (457 mm).
Clearance at the top should be a minimum of 5 ft
(1.52 m) from any structure, overhang, or
projections from the wall.
IMPORTANT NOTE: Mechanical and gravity outdoor
air intake openings for HVAC supply air systems
shall be located not less than 10 feet (3048mm)
horizontally from the generator enclosure. See
Section 401 in the ICC Mechanical Code for any
additional requirements.
•DO NOT install under wooden decks or structures
unless there is at least 5 ft (1.52 m) of clearance
above the generator.
•Install the unit where rain gutter down spouts, roof
run-off, landscape irrigation, water sprinklers, or
sump pump discharge does not flood the unit or
spray the enclosure, including any air inlet or outlet
openings.
•Install the unit where services will not be affected
or obstructed, including concealed, underground,
or covered services such as electrical, fuel, phone,
air conditioning, or irrigation. This could affect
warranty coverage.
•Where strong prevailing winds blow from one
direction, face the generator air inlet openings to
the prevailing winds.
•Install the generator as close as possible to the fuel
supply to reduce the length of piping. REMEMBER
THAT LAWS OR CODES MAY REGULATE THE
DISTANCE AND LOCATION. In the absence of
local codes regarding placement or clearance, we
recommend following these guidelines:
– Install the generator as close as possible to the
transfer switch. REMEMBER THAT LAWS OR
CODES MAY REGULATE THE DISTANCE AND
LOCATION.
– The generator must be installed on a level
surface. The generator must be level within a 0.5
in (13 mm) all around.
– The generator is typically placed on pea gravel,
compacted soil, crushed stone, or a concrete
pad. Check local codes to see what type is
required. If a concrete pad is required, all
applicable codes should be followed.
Verify Wi-Fi Range
Refer to the Wi-Fi manual shipped with the unit if
planning to use the Wi-Fi feature.
Installation Guidelines for Stationary Air-Cooled
Generators
See Figure 3-1. NFPA 37 is the The National Fire
Protection Association’s standard for the installation and
use of stationary combustion engines. Its requirements
limit the spacing of an enclosed generator set from a
structure or wall.
NFPA 37, Section 4.1.4, Engines Located Outdoors:
Engines, and their weatherproof housings if provided,
installed outdoors shall be located at least 5 ft (1.52 m)
from openings in walls and at least 5 ft (1.52 m) from
structures having combustible walls. A minimum
separation shall not be required where the following
conditions exist:
1. The adjacent wall of the structure has a fire
resistance rating of at least one hour.
2. The weatherproof enclosure is constructed of
noncombustible materials and it has been
demonstrated that a fire within the enclosure will
not ignite combustible materials outside the
enclosure.

Site Selection and Preparation
Installation Guidelines for 60 Hz Air-Cooled Generators 15
Annex A — Explanatory Material
A4.1.4 (2) Means of demonstrating compliance are by
means of full scale fire test or by calculation procedures.
Because of the limited spaces frequently available for
installation, it has become apparent that exception (2)
would be beneficial for many residential and commercial
installations. With that in mind, the manufacturer
contracted with an independent testing laboratory to run
full scale fire tests to assure the enclosure will not ignite
combustible materials outside the enclosure.
NOTE: Southwest Research Institute testing approves
18 in (457 mm) installation minimum from structure
(Figure 3-1, C). Southwest Research Institute is a
nationally recognized third party testing and listing
agency.
The criteria was to determine the worst case fire scenario
within the generator and to determine the ignitability of
items outside the engine enclosure at various distances.
The enclosure is constructed of non-combustible
materials, and the results and conclusions from the
independent testing lab indicated that any fire within the
generator enclosure would not pose any ignition risk to
nearby combustibles or structures, with or without fire
service personnel response.
Figure 3-2. Southwest Research Institute Marking
http://www2.swri.org/www2/listprod/
DocumentSelection.asp?ProductID=973&IndustryID=2
Based on this testing and the requirements of NFPA 37,
Sec 4.1.4, the guidelines for installation of the generators
listed above are changed to 18 in (457 mm) from the
back side of the generator to a stationary wall or building
(C). For adequate maintenance and airflow clearance,
the area above the generator should be at least 5 ft (1.52
m) with a minimum of 3 ft (0.91 m) at the front and ends
of the enclosure. This includes trees, shrubs, and
bushes. Vegetation not in compliance with these
clearance parameters could obstruct air flow. In addition,
exhaust fumes from the generator could inhibit plant
growth. See Figure 3-1 and the installation drawing
within the owner’s manual for details.
NOTE: If the generator is not set to OFF, it can crank and
start as soon as the battery cables are connected. If the
utility power supply is not turned off, sparking can occur
at the battery posts and cause an explosion.
Site Preparation
•Locate the mounting area as close as possible to
the transfer switch and fuel supply.
•Leave adequate room around the area for service
access (check local code), and place high enough
to keep rising water from reaching the generator.
•Choose an open space which will provide
adequate and unobstructed airflow.
•Place the unit so air vents will not become clogged
with leaves, grass, snow, or debris. Verify exhaust
fumes will not enter any building through eaves,
windows, ventilation fans, or other air intakes (see
Site Selection).
•Select the type of base, such as—but not limited
to—compacted soil, gravel, or concrete, as desired
or as required by local laws or codes. Verify your
local requirements before selecting.

Material Sufficient for Level Installation
See Figure 3-3. Prepare a rectangular area
approximately 5 in (127 mm) deep (A) and approximately
6 in (152 mm) longer and wider (B) than the footprint of
the generator. Verify the surface where the generator will
be mounted is compacted, leveled, and will not erode
over time. A concrete pad can be poured if desired or
required.
Figure 3-3. Compacted Soil or Gravel Pad
NOTE: If a concrete pad is required, follow all applicable
federal, state, or local codes.
Transportation Recommendations
Use a suitable cart or equipment to carry the generator,
including the wooden pallet, to the installation site. Place
cardboard between the cart and generator to prevent any
damage or scratches to the generator.
IMPORTANT NOTE: Do not lift, carry, or move the
generator by grasping the louvers. Doing so may
bend or damage the sheet metal.
Placement on Roofs, Platforms,
and Other Supporting Structures
Where required to place the generator on a roof,
platform, or other supporting structure, like a deck, the
generator shall be placed in accordance with the
requirements in NFPA 37, Section 4.1.3. The generator
can be located 18 in (457 mm) from structures having
combustible walls and 5 ft (1.52 m) from any operable
opening in the structure. The surface beneath the
generator and beyond shall be noncombustible to a
minimum distance of 12 in (30.5 cm). Consult with the
local Building Inspection Department or Fire Department
to determine which noncombustible materials are
approved for installation.
