1.4 — Exhaust Hazards
• Generator engine exhaust contains DEADLY carbon monoxide, an odorless, colorless, poisonous gas. Breathing
carbon monoxide can cause dizziness, throbbing temples, nausea, muscular twitching, headache, vomiting,
weakness, sleepiness, inability to think clearly, fainting, unconsciousness or even death. If any carbon monoxide
poisoning symptom is experienced, move into fresh air and immediately seek medical attention.
• This generator is designed for OUTDOOR installation ONLY. Never operate the generator inside any garage or
other enclosed space.
1.5 — Electrical Hazards
• All generators covered by this manual produce dangerous electrical voltages that can cause fatal electrical
shock. Utility power delivers extremely high and dangerous voltages to the transfer switch, as does the standby
generator when it is in operation. Avoid contact with bare wires, terminals, connections, etc. while the unit is running. Ensure all appropriate covers, guards and barriers are in place, secured and/or locked before operating the
generator. If work must be done around an operating unit, stand on an insulated, dry surface to reduce potential
shock hazard.
• Do not handle any kind of electrical device while standing in water, while barefoot, or while hands or feet are wet.
DANGEROUS ELECTRICAL SHOCK MAY RESULT.
• The generator may crank and start at any time when utility power is lost. When this occurs, load circuits are
transferred to the STANDBY (generator) power source. Before working on the generator, always move the Main
Circuit Breaker switch on the control panel down to the OFF (Open) position, press the OFF key on the control
panel keypad, remove the 7.5 amp fuse, and disconnect the battery negative cable (black) from the battery negative (-) terminal.
• In case of accident caused by electric shock, immediately shut down the source of electrical power. If this is not
possible, attempt to free the victim from the live conductor. AVOID DIRECT CONTACT WITH THE VICTIM. Use
a nonconducting implement, such as a dry rope or board, to free the victim from the live conductor. If the victim is
unconscious, apply first aid and get immediate medical help.
• Never wear jewelry when working on this equipment. Jewelry can conduct electricity resulting in electric shock,
or may get caught in moving parts resulting in injury.
1.6 — Fire Hazards
• For fire safety, the generator must be installed and maintained properly. Installation MUST always comply with
applicable codes, standards, laws, regulations and product Installation Manual guidelines. Adhere strictly to
local, state, and national electrical and building codes. Comply with regulations of the Occupational Safety and
Health Administration (OSHA). Also, ensure that the generator is installed in accordance with the manufacturer’s
instructions and recommendations. Following proper installation, do nothing that might alter a safe installation
and render the unit in noncompliance with the aforementioned codes, standards, laws and regulations.
• Keep a fire extinguisher near the generator at all times. Extinguishers rated “ABC” by the National Fire Protection
Association are appropriate for use on the standby generator. Keep the extinguisher properly charged and be
familiar with its use. Consult the local fire department with any questions pertaining to fire extinguishers.
1.7 — Explosion Hazards
• Do not smoke around the generator. Wipe up any fuel or oil spills immediately. Ensure that no combustible materials are left in the generator compartment, or on or near the generator as FIRE or EXPLOSION may result. Keep
the area surrounding the generator clean and free from debris.
+
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 electrical system from the utility distribution system when the generator is operating (NEC 702). Failure to
isolate an electrical system by such means will result in damage to the generator and also may result
in injury or death to utility power workers due to backfeed of electrical energy.

2.4 — Coolant Water Treatment
Use of improper coolants can damage the engine cooling system. Use demineralized water or distilled water for best
results. Hard water causes scale deposits, which reduces cooling efficiency and raises internal temperatures, possibly
leading to engine damage. Use an anti-corrosive to prevent rot in summer and anti-freeze to prevent freezing in winter.
Dilute the anti-freeze based on a theoretical temperature that is 9-18°F (5-10°C) below the lowest temperature
expected in the area. A ratio of 40-60% is most common range.

3.8 — Operational Checks
+
The following procedures require special tools and skills. Contact a Generac Dealer or an authorized
service provider to perform these tasks.
3.8.1— Self Test
Upon power up, the controller goes through a system self test which checks for the presence of utility voltage on the
DC circuits. This is done to prevent damage if the installer mistakenly connects AC utility power sense wires into the
DC terminal block. If utility voltage is detected, the controller displays a warning message and locks out the generator,
thereby preventing damage to the controller. Remove power to the controller to clear this warning.
Utility voltage must be turned on and present at the N1 and N2 terminals inside the generator control panel for this test
to be performed and pass.
Before starting, complete the following:
1.
Verify that the generator is OFF. A red LED on the control pad illuminates to confirm that the system is in the OFF
mode.
2.
Verify that the Main Circuit Breaker switch on the generator control panel is in the OFF (Open) position.
3.
Turn off all circuit breakers/electrical loads that will be powered by the generator.
4.
Check the fuel level, coolant level, and engine lubricating oil level. See Subsections 5.7.2, 5.7.4, and 5.7.6,
respectively.
During initial start up only, the generator may exceed the normal number of start attempts and experience an “over
crank” fault. This is due to accumulated air in the fuel system during installation. Reset the control board and restart up
to two more times, if necessary. If unit fails to start, contact the local dealer for assistance.
3.8.2— Check Manual Transfer Switch Operation
Refer to the manufacturer’s instructions.
+
Do not attempt manual transfer switch operation until all power voltage supplies to the transfer switch
have been positively turned off. Failure to turn off all power voltage supplies will result in extremely
hazardous and possibly fatal electrical shock.
Owner’s Manual for Stationary Diesel Generators
15
Activation and Startup
3.8.3— Electrical Checks
Complete electrical checks as follows:
1.
Verify that the generator is OFF. A red LED on the control pad illuminates to confirm that the system is in the OFF
mode.
2.
Verify that the Main Circuit Breaker switch on the generator control panel is in the OFF (Open) position.
3.
Turn OFF all circuit breakers/electrical loads that will be powered by the generator.
4.
Turn on the utility power supply to the transfer switch using the means provided (such as a utility main line circuit
breaker).
+
The transfer switch is now electrically “hot.” Contact with “hot” parts will result in extremely hazardous and possibly fatal electrical shock.
5.
Use an accurate AC voltmeter to check utility power source voltage across transfer switch terminals N1, N2, and
N3 (if three phase). Normal line-to-line voltage should be equivalent to rated unit voltage.
6.
Check utility power source voltage across terminals N1, N2, and N3 (if three phase) and the transfer switch neutral lug.
7.
When certain that utility supply voltage is compatible with transfer switch and load circuit ratings, turn OFF the
utility power supply to the transfer switch.
8.
Press MANUAL on the control pad to crank and start the engine.
9.
Allow the engine to warm up for about five minutes. Move the Main Circuit Breaker switch on the generator control panel up to the ON (or closed) position.
+
Generator power voltage is now supplied to the transfer switch. Contact with live transfer switch parts
will result in dangerous and possibly fatal electrical shock.
10.
Connect an accurate AC voltmeter and a frequency meter across transfer switch terminal lugs E1, E2, and E3 (if
three phase).
11.
Successively connect the AC voltmeter test leads across terminal lugs E1, E2, and E3 (if three phase) and neutral; then across E2 and neutral. Voltage reading in each case should match utility voltage reading. If system is
three phase, verify that generator phase rotation matches utility phase rotation.
12.
Move the Main Circuit Breaker switch on the generator control panel down to the OFF (Open) position.
13.
Press OFF on the control pad to shut the engine down.
+
Do not proceed unless certain that generator AC voltage and frequency are correct and within the
stated limits.
3.8.4— Test Generator Under Load
To test the generator set with electrical loads applied, proceed as follows:
1.
Verify that the generator is OFF. A red LED on the control pad illuminates to confirm that the system is in the OFF
mode.
2.
Turn OFF all breakers/electrical loads that will be powered by the generator.
3.
Turn OFF the utility power supply to the transfer switch, using the means provided (such as a utility main line circuit breaker).
+
4.
16
Do not attempt manual transfer switch operation until all power voltage supplies to the transfer switch
have been positively turned off. Failure to turn off all power voltage supplies will result in extremely
hazardous and possibly fatal electrical shock.
Manually set the transfer switch to the STANDBY position, i.e., load terminals connected to the generator’s E1,
E2, and E3 (if three phase) terminals.

Operation
4.9.1— Automatic Sequence of Operation
4.9.1.1—Utility Failure
If the control pad is set to AUTO when the utility power fails (falls below 60% of nominal, dealer programmable), a ten
second Start-Up Delay timer is started (user programmable). If utility power is still absent when the time expires, the
engine cranks and starts.
Once started, a five second engine Warm-Up Delay timer starts (user programmable). When the time has elapsed, the
load is transferred to the generator. If utility power is restored (above 80% of nominal, dealer programmable) between
the time the engine is first started and expiration of the warm-up time, the controller completes the start cycle and then
runs through its normal cool-down cycle (while the load remains on the utility source throughout the episode).
4.9.1.2—Cranking
The cyclic cranking is controlled as follows:
Fifteen (15) seconds crank, seven (7) seconds rest, seven (7) seconds crank, seven (7) seconds rest; this sequence is
repeated for a total of six (6) crank cycles.
4.9.1.3—Load Transfer
With the generator running, the transfer of load is dependent upon the operating mode as follows:
• Starts and runs if utility power fails (falls below 60% of nominal) for five consecutive seconds (adjustable).
• Starts a five second (adjustable) engine warm-up timer.
• Does not execute transfer if utility power returns before expiration of warm-up timer (but
finishes the warm-up and cool-down cycles).
• Transfers back to utility once utility power returns (above 80% of nominal) for fifteen
consecutive seconds.
AUTO
• Only shuts down if OFF is pressed or an alarm shutdown occurs.
• Once utility power returns, starts a cool-down cycle before it shuts down.
NOTE: Cool-down cycle is five minutes if turbocharger equipped, one minute if naturally
aspirated.
EXERCISE
• Only works in the AUTO mode.
• Does not exercise if generator is already running in AUTO.
• During exercise cycle, transfers only if utility power fails for ten consecutive seconds.
• Engine cranks and runs even if utility power is present, but does not transfer to generator.
• Transfers to generator if utility fails (falls below 60% of nominal) for ten consecutive secMANUAL
onds.
• Transfers back to utility when utility returns for fifteen consecutive seconds. The engine
continues to run until the AUTO or OFF key is pressed.
4.10 — Transfer Switch Manual Operation
DO NOT attempt to activate the transfer switch manually until all power voltage supplies to the switch
have been completely turned off. Failure to turn off all power voltage supplies may result in extremely
hazardous and possibly fatal electrical shock.
Prior to automatic operation, manually exercise the transfer switch to verify that there is no binding or interference with
proper operation of the mechanism. Manual operation of the transfer switch is required if automatic operation fails.
