Safety

1.2 — Safety Information

Study these safety rules carefully before operating or servicing this equipment. Become familiar with this Owner’s Man-

ual and with the unit. The generator can operate safely, efficiently and reliably only if it is properly installed, operated

and maintained. Many accidents are caused by failing to follow simple rules or precautions.

The manufacturer cannot anticipate every possible circumstance that might involve a hazard. The warnings in this

manual, and on tags and decals affixed to the unit are not all-inclusive. If using a procedure, work method or operating

technique the manufacturer does not specifically recommend, ensure that it is safe for personnel. Also make sure the

procedure, work method or operating technique used does not render the generator unsafe.

Despite the safe design of this generator, operating this equipment imprudently, neglecting its mainte-

nance or being careless can cause possible injury or death. Permit only responsible and capable per-

sons to install, operate and maintain this equipment.

Potentially lethal voltages are generated by these machines. Ensure steps are taken to make the

machine safe before attempting to work on the generator.

Parts of the generator are rotating and/or hot during operation. Exercise care near a running generator.

The installation of this generator must always comply with applicable codes, standards, laws and regu-

lations.

A running generator gives off DEADLY carbon monoxide, an odorless, colorless, poisonous gas.

Breathing carbon monoxide can cause dizziness, throbbing temples, nausea, muscular twitching, head-

ache, vomiting, weakness, sleepiness, inability to think clearly, fainting, unconsciousness or even

death.

The control panel for this unit is intended to be operated by qualified service personnel only.

1.3 — General Hazards

• For safety reasons, this equipment should only be installed, serviced and repaired by a Service Dealer or other

competent, qualified electrician or installation technician who is familiar with applicable codes, standards, regula-

tions and product Installation Manual guidelines. The operator also must comply with all such codes, standards,

regulations and product Installation Manual guidelines.

• The engine exhaust fumes contain carbon monoxide, which can be DEADLY. This dangerous gas, if breathed in

sufficient concentrations, can cause unconsciousness or even death. DO NOT alter or add to the exhaust system

or do anything that might render the system unsafe or in noncompliance with applicable codes and standards.

• Install a carbon monoxide alarm indoors, according to manufacturer’s instructions/recommendations.

• Adequate, unobstructed flow of cooling and ventilating air is critical for correct generator operation. Do not alter

the installation or permit even partial blockage of ventilation provisions, as this can seriously affect safe operation

of the generator. The generator MUST be installed and operated outdoors only.

• Keep hands, feet, clothing, etc. away from drive belts, fans, and other moving or hot parts. Never remove any

drive belt or fan guard while the unit is operating.

• When working on this equipment, remain alert at all times. Never work on the equipment when physically or men-

tally fatigued.

• Inspect the generator regularly, and contact the nearest Dealer for parts needing repair or replacement.

• Before performing any maintenance on the generator, remove the control panel fuse and disconnect the Nega-

tive (-) battery cable to prevent accidental startup. When disconnecting battery cables always remove the NEGA-

TIVE (-) cable first. When reconnecting the cables, connect the POSITIVE (+) cable first.

• Never use the generator or any of its parts as a step. Stepping on the unit can stress and break parts, and may

result in dangerous operating conditions from leaking exhaust gases, fuel leakage, oil leakage, etc.

Safety

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 run-

ning. 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 neg-

ative (-) 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 mate-

rials 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 elec-

trical 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.

Freezing Point °F (°C)

Coolant (% Volume)

Water (% Volume)

-13 (-25)

-31 (-35)

-58 (-50)

NOTE: Use only Peak Fleet-Charge® 50/50 ethylene glycol type coolant (available from any authorized

dealer).

Do not use propylene glycol type coolant. Using the wrong coolant, mixing different types of coolant,

or even mixing different brands of the correct type of coolant, can produce unsatisfactory results, pos-

sibly leading to engine damage.

2.5 — Fuel Requirements

IMPORTANT! DO NOT use Home Heating Oil or Bio-Diesel Fuel.

Use No. 2D diesel fuel when temperatures are above freezing. When temperatures are below freezing, blend No.1D

diesel fuel and No. 2D diesel fuel together for a climate adjusted fuel ratio.

Starting October 1, 2010, diesel fuel must also meet the following requirements:

• Sulfur content of 15 parts per million (ppm) maximum.

• Minimum Cetane index of 40.

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

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 hazard-

ous 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 neu-

tral 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 con-

trol 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 neu-

tral; 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 cir-

cuit breaker).

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.

4. 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.

Activation and Startup

5. Press MANUAL on the control pad. The engine will crank and start.

6. Allow the engine to warm up for a few minutes.

7. Move the Main Circuit Breaker switch on the generator control panel up to the ON (or closed) position. The

switch is now powered by the standby generator.

8. Turn ON the circuit breaker/electrical loads powered by the generator.

9. Connect a calibrated AC voltmeter and a frequency meter across terminal lugs E1, E2, and E3 (if three phase).

Voltage should be approximately unit rated voltage. Check with clamp on amp meter to ensure unit is not over-

loaded.

10. Let the generator run at full rated load for 20-30 minutes. Listen for unusual noises, vibration or other indications

of abnormal operation. Check for oil leaks, evidence of overheating, etc.

11. When testing under load is complete, turn OFF electrical loads.

12. Move the Main Circuit Breaker switch on the generator control panel up to the OFF (or open) position.

13. Allow the engine to run at no-load for 2-5 minutes.

14. Press OFF on the control pad to shut the engine down. A red LED illuminates to confirm that the system is in the

OFF mode.

3.8.5— Check Automatic Operation

To check the system for proper automatic operation, 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. Install front cover of the transfer switch.

3. Turn ON the utility power supply to the transfer switch, using the means provided (such as a utility main line cir-

cuit breaker).

NOTE: Transfer Switch will transfer back to utility position.

4. Move the Main Circuit Breaker switch on the generator control panel up to the ON (or closed) position.

5. Press AUTO on the control pad. The system is now ready for automatic operation.

6. Turn OFF the utility power supply to the transfer switch.

With the generator ready for automatic operation, the engine will crank and start when the utility source power is turned

OFF after a 10 second delay (factory default setting). After starting, the transfer switch connects load circuits to the

standby side. Let the system operate through its entire automatic sequence of operation.

With the generator running and loads powered by generator AC output, turn ON the utility power supply to the transfer

switch. The system transfers back to the utility position and then runs through the cool down cycle and shuts down.

Operation

4.6.2— User Programmable

4.6.2.1—Start-Up Delay Timer

A programmable line interrupt delay (or Start-Up Delay) timer is provided. When utility voltage fails (falls below 60% of

nominal), the start-up delay timer is started. If the voltage rises above the Utility Volts Low threshold, the timer is reset.

If the utility voltage remains below the threshold during the duration of the timer, the unit cranks and starts.

NOTE: The factory default setting is five seconds, but is adjustable from 2 to 1500 seconds.

4.6.2.2—Warm-Up Delay Timer

A programmable Warm-Up Delay timer is provided. As soon as the generator starts, the warm-up timer is started.

When the warm-up timer expires, the control transfers load to the generator (through the transfer switch) if the utility

voltage is less than 80% of nominal. If utility voltage is greater than the threshold at expiration of the warm-up time, the

load is not transferred to the generator and a cool-down period begins. At the end of the cool-down period, the gener-

ator stops.

NOTE: The factory default setting is five seconds, but is adjustable from 5 to 1500 seconds.

4.7 — USB Port for Firmware Updates

A USB port is located beneath the rubber flap on the control panel, and is provided for firmware updates. Firmware

updates must be performed by an Authorized Service Dealer.

NOTE: The USB port is intended for use with a USB thumb drive only. The USB port is not intended for charging

devices such as phones or laptops. Do not connect any consumer electronics to the USB port.

4.8 — Battery Charger

NOTE: The battery charger is integrated into the control panel module.

The battery charger ensures:

• Output is continually optimized to promote maximum battery life.

• Charging levels are safe.

NOTE: A warning message is displayed on the LCD screen when the battery requires service.

4.9 — Transfer Switch Automatic Operation

In AUTO, the generator starts automatically when utility source voltage drops below the preset level. Once the unit

starts, loads are transferred to the standby power source.

To select automatic operation:

1. Verify that the transfer switch main contacts are set to the UTILITY position (loads connected to the utility power

source).

2. Verify that normal UTILITY power source voltage is available to transfer switch terminal lugs N1, N2 and N3 (if

three phase).

3. Move the Main Circuit Breaker switch on the control panel up to the ON (Closed) position.

4. Press AUTO on the control pad. A green LED illuminates to confirm that the system is in the AUTO mode.

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 sec-

onds (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.

• Only shuts down if OFF is pressed or an alarm shutdown occurs.

AUTO

• 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 sec-

MANUAL

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
