Any attempt to crank or start the engine before
it has been properly serviced with the recom-
mended oil may result in an engine failure.
n
Do not use any chromate base rust inhibitor
with ethylene glycol base anti-freeze or chro-
mium hydroxide (“green slime”) forms and will
cause overheating. Engines that have been
operated with a chromate base rust inhibitor
must be chemically cleaned before adding eth-
ylene glycol base anti-freeze. Using any high
silicate anti-freeze boosters or additives will
also cause overheating. The manufacturer also
recommends that any soluble oil inhibitor is
NOT used for this equipment.
n
Do not remove the radiator pressure cap while
the engine is hot or serious burns from boiling
liquid or steam could result.
n
Ethylene glycol base antifreeze is poisonous.
Do not use mouth to siphon coolant from the
radiator, recovery bottle or any container. Wash
hands thoroughly after handling. Never store
used antifreeze in an open container because
animals are attracted to the smell and taste of
antifreeze even though it is poisonous to them.

The Stationary Emergency Generator may be equipped with one of
the following fuel systems:
• Natural gas fuel system
• Propane vapor (LPV) fuel system
Recommended fuels should have a Btu content of at least 1,000
Btu's per cubic foot for natural gas; or at least 2,520 Btu's per
cubic foot for LP gas. Ask the fuel supplier for the Btu content of
the fuel.
NOTE:
The fuel consumption requirements are identified in the
Specifications section of the Owner's Manual. Refer to the
Installation Manual if assistance is required for the sizing of
the pipe diameter for the generator. Any piping used to connect
the generator to the fuel supply should be of adequate size to
achieve the 100% load fuel consumption requirements identi-
fied in the Specifications section regardless of actual load.
NOTE:
The recommended fuel pressure is identified in the Specifications
section this manual.
NOTE:
It is the responsibility of the installer to make sure that only
the correct recommended fuel is supplied to the generator fuel
system. Thereafter, the owner/operator must make certain that
only the proper fuel is supplied.
Natural gas is supplied in its vapor state. In most cases, the gas
distribution company provides piping from the main gas distribu-
tion line to the standby generator site. The following information
applies to natural gas fuel systems.
• Gas pressure in a building is usually regulated by national, state
and local codes.
• To reduce gas pressure to a safe level before the gas enters a
building, a primary regulator is needed. The natural gas supplier
may or may not supply such a regulator.
• It is the responsibility of the gas supplier to make sure sufficient
gas pressure is available to operate the primary regulator.
• Gas pressure at the inlet to the fuel shutoff solenoid must never
exceed approximately 14 inches water column (0.5 psi).
This type of system utilizes the vapors formed above the liquid
fuel in the supply tank. Approximately 10 to 20 percent of the tank
capacity is needed for fuel expansion from the liquid to the vapor
state. The vapor withdrawal system is generally best suited for
smaller engines that require less fuel. The installer should be aware
of the following:
• When ambient temperatures are low and engine fuel consump-
tion is high, the vapor withdrawal system may not function
efficiently.
• Ambient temperatures around the supply tank must be high
enough to sustain adequate vaporization, or the system will not
deliver the needed fuel volume.
• In addition to the cooling effects of ambient air, the vaporization
process itself provides an additional cooling effect.

ALTERNATOR AC LEAD
CONNECTIONS
The electrical wires in the unit’s AC connection (lower) panel
should be installed according to the number of leads and the
voltage/phase required for the application. The voltage and phase
are described on the generator data label. The number of lead
wires can be identified using the Specifications section and the
power output rating on the generator data label. For example, if
the generator produces 130kW, 277/480 Volt, 3-phase power, the
generator has 12 alternator output leads. Figure 7.3 describes the
stator power winding connection for the generator.
FOUR-LEAD, SINGLE-PHASE STATOR
Four-lead alternators (see Figure 7.1) are designed to supply elec-
trical loads with voltage code A(240V, 1-phase, 60 Hz). Electrical
power is produced in the stator power windings. These windings
were connected at the factory to the main circuit breaker as shown
in Figure 7.1.
The rated voltage between each circuit breaker terminal is 240V.
The rated voltage between each circuit breaker terminal and the
neutral point 00 is 120V.

ALTERNATOR POWER WINDING
CONNECTIONS
3-PHASE ALTERNATORS ("Y" CONFIGURATION)
The Stationary Emergency Generator is designed to supply
3-phase electrical loads. Electric power is produced in the alterna-
tor power windings. These windings were connected at the factory
to the main circuit breaker with a “Y” configuration as shown in
Figures 7.2 through 7.6.
The rated voltage between circuit breaker terminals E1-E2, E1-E3
and E2-E3 is 480V, 208V or 600V depending on the model.
The rated voltage between each circuit breaker terminal and the
neutral point 00 is 277V, 120V, or 346V depending on the model.

Before working on the Stationary Emergency
Generator, ensure the following:
CHECK ENGINE OIL
Check engine crankcase oil level (Figure 10.1) according to the
Service Schedule and SIB10-10-L24G.
Remove oil dipstick and wipe dry with a clean, lint-free cloth.
Install oil dipstick, then remove again.
Oil should be between FULL and ADD marks.
If oil level is below the dipstick ADD mark, remove oil fill cap-.
Add the recommended oil to bring oil level up to the FULL
mark. DO NOT FILL ABOVE THE “FULL” MARK. See “Engine Oil
Recommendations” for recommended oils.

CHANGING ENGINE OIL
nHot oil may cause burns. Allow engine to cool
before draining oil. Avoid prolonged or repeat-
ed skin exposure with used oil. Thoroughly
wash exposed areas with soap.
Refer to the Service Schedule for engine oil and filter change fre-
quencies.
Drain the oil while the engine is still warm from running. This
means warm up the engine, shut it down and drain immediately
as follows:
1. Remove the drain hose from its retaining clip or cut the zip-tie
securing the oil drain hose.
2. Loosen and remove OIL DRAIN HOSE CAP. Drain oil com-
pletely into suitable container.
3. When all oil has drained, install and tighten OIL DRAIN HOSE
CAP and secure drain hose with a new zip-tie, or place the
hose in its retaining clip.
4. Turn OIL FILTER (Figure 10.1) counterclockwise and remove.
Properly dispose of old filter.
5. Apply light coating of new engine oil to seal of new oil fil-
ter. Install FILTER and tighten by hand only. DO NOT OVER
TIGHTEN.
6. Remove OIL FILL CAP and add recommended oil. Crankcase
oil capacity is listed in the "Specifications" section.
nAfter refilling the crankcase with oil, always
check oil level on dipstick. NEVER OPERATE
ENGINE WITH OIL BELOW THE DIPSTICK “ADD”
MARK.
7. Start engine and check for oil leaks.
8. Shut OFF engine and wait 10 minutes for the oil to settle down
into the oil pan. Recheck oil level on dipstick. DO NOT fill
above the dipstick "FULL" mark.
9. Dispose of used oil at a proper collection center.
COOLING INTAKE/OUTLET
Air intake and outlet openings in the generator compartment must
be open and unobstructed for continued proper operation. This
includes such obstructions as high grass, weeds, brush, leaves
and snow.
Without sufficient cooling and ventilating air flow, the engine/gen-
erator quickly overheats, which causes it to shut down. (See the
installation diagram.)
The exhaust system parts from this product get
extremely hot and remains hot after shutdown.
High grass, weeds, brush, leaves, etc. must
remain clear of the exhaust. Such materials may
ignite and burn from the heat of the exhaust
system.
INSPECT COOLING SYSTEM
Inspect engine cooling system. See the Service Schedule.
Check hoses for damage, deterioration, leaks, etc. Correct any
discrepancies found.
Check hose clamps for tightness.
