GENERAL HAZARDS

• For safety reasons, the manufacturer recommends that this equipment be

installed, serviced and repaired by a Service Dealer or other competent,

qualified electrician or installation technician who is familiar with applicable

codes, standards and regulations. The operator also must comply with all

such codes, standards and regulations.

• 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 battery operated carbon monoxide alarm indoors, according to

manufacturer’s instructions/recommendations.

• Adequate, unobstructed flow of cooling and ventilating air is critical to

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 mentally fatigued.

• Inspect the generator regularly, and contact the nearest Dealer for

parts needing repair or replacement.

• Before performing any maintenance on the generator, disconnect its

battery cables to prevent accidental start up. Disconnect the cable

from the battery post indicated by a NEGATIVE, NEG or (–) first, then

remove the POSITIVE, POS or (+) cable. When reconnecting the

cables, connect the POSITIVE cable first, the NEGATIVE cable last.

• 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.

ELECTRICAL HAZARDS

• All generators covered by this manual produce dangerous electrical

voltages and 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 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 National Electrical Code (NEC) requires the frame and external

electrically conductive parts of the generator to be connected to an

approved earth ground. Local electrical codes also may require proper

grounding of the generator electrical system.

• After installing this home standby electrical system, the generator may

crank and start at any time without warning. When this occurs, load

circuits are transferred to the STANDBY (generator) power source. To

prevent possible injury if such a start and transfer occur, always set

the generator’s AUTO/OFF/MANUAL switch to its OFF position before

working on equipment and remove the 15A fuse from the generator

control panel.

• 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 components causing injury.

FIRE HAZARDS

• For fire safety, the generator must be installed and maintained

properly. Installation must always comply with applicable codes,

standards, laws and regulations. Adhere strictly to local, state

and national electrical and building codes. Comply with regulations

the Occupational Safety and Health Administration (OSHA) has

established. 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 electric system. Keep the extinguisher properly

charged and be familiar with its use. Consult the local fire department

with any questions pertaining to fire extinguishers.

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.

• Gaseous fluids such as natural gas and liquid propane (LP) gas are

extremely EXPLOSIVE. Install the fuel supply system according to

applicable fuel-gas codes. Before placing the home standby electric

system into service, fuel system lines must be properly purged and

leak tested according to applicable code. After installation, inspect the

fuel system periodically for leaks. No leakage is permitted.

UNPACKING/INSPECTION

After unpacking, carefully inspect the contents for damage.

• This standby generator set is ready for installation with a factory

supplied and pre-mounted base pad and has a weather protective

enclosure that is intended for outdoor installation only.

• This UL listed standby generator set may be packaged with an

automatic transfer switch with built in load center. The combination

transfer switch and load center is pre-wired with a two foot and 30

foot conduit. Circuit breakers for emergency circuit connections are

included (if equipped).

• This UL listed, 2-pole switch is rated at 100 or 200 AC amperes at

250 volts maximum. The 100 Amp transfer switch is for indoor use

only. The 200 Amp transfer switch is for indoor/outdoor use (if

equipped).



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 700,

701 & 702). Failure to isolate an electrical system

by such means will result in damage to the gen-

erator and also may result in injury or death to

utility power workers due to backfeed of electrical

energy.

If any loss or damage is noted at time of delivery, have the person(s)

making the delivery note all damage on the freight bill or affix their

signature under the consignor’s memo of loss or damage.

If a loss or damage is noted after delivery, separate the damaged

materials and contact the carrier for claim procedures.

“Concealed damage” is understood to mean damage to the contents of a

package that is not in evidence at the time of delivery, but is discovered

later.

To properly open the roof, press down on the center top lip and release

the latch. If pressure is not applied from the top, the roof may appear

stuck. Always verify that the side lock is unlocked before attempting to lift

the roof.

NEC REQUIREMENTS

Local code enforcement may require that AFCI’s be incorporated

into the transfer switch distribution panel. The Transfer Switch

provided with this generator has a distribution panel that will

accept AFCI’s.

Siemens Part No. Q115AF - 15A or Q120AF - 20A can be

obtained from a local electrical wholesaler and will simply replace

any of the single pole circuit breakers supplied in the Transfer

Switch distribution panel.

BEFORE YOU BEGIN

Contact the local inspector or City Hall to be aware of all federal,

state and local codes that could impact the installation. Secure all

required permits before starting the job.

Carefully read and follow all of the procedures and safety

precautions detailed in the installation guide. If any portion of the

installation manual, technical manual or other factory-supplied

documents is not completely understood, contact a dealer for

assistance.

Fully comply with all relevant NEC, NFPA and OSHA standards

as well as all federal, state and local building and electric codes.

As with any generator, this unit must be installed in accordance

with current NFPA 37 and NFPA 70 standards as well as any other

federal, state, and local codes for minimum distances from other

structures.

SITE PREPARATION AND GENERATOR

PLACEMENT

1. 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 that will provide adequate and

unobstructed airflow (see the “Location” section in the

Owner’s Manual).

2. Place the unit so air vents won’t become clogged with leaves,

grass, snow or debris. Make sure exhaust fumes will not enter

the building through eaves, windows, ventilation fans or other

air intakes.

Dig a rectangular area approximately five inches deep and

about six inches longer and wider than the footprint of the

generator. Cover with polyurethane film and fill with pea gravel

or crushed stone. Compact and level the stone. A concrete

pad can be poured if desired.

3. Inspect the generator for shipping damage and if necessary,

file a claim with the shipper.

Remove the bands holding the generator to the wooden pallet.

4. Make sure the lifting equipment to be used has sufficient

capacity to safely handle the weight of the generator.

Use nylon lifting straps and connect them to the lifting eyes

on each corner of the base frame to avoid damaging the

enclosure.

5. Set the generator onto the pad so that the gravel bed extends

several inches beyond the generator on all sides.

Make sure the generator is level within ½ inch.

6. Connect an approved ground strap to the grounding lug on the

base frame and to an approved earth ground or grounding rod

as specified by local regulations.

General Information

5

7. Check the engine oil and, if necessary, add enough of the

recommended oil to bring the level up to the FULL mark on

the dipstick. Be careful not to overfill the crankcase.

CONVERTING TO LP VAPOR

1. The generator was configured for natural gas operation at the

factory. Switching over to LP Vapor is a simple procedure.

On models with a single cylinder engine, begin by

disconnecting and removing the battery if installed.

2. Take the plastic T-handle fuel selector in the poly bag supplied

with the generator and locate the selector tab on the air box

cover. Insert the pin end into the hole in the selector tab

and pull outward to overcome spring pressure. Then twist

clockwise 90 degrees and allow the selector to return in once

aligned with the LP position.

3. On 10 kW units, open the roof, loosen the forward clamp

on the air inlet hose, and slide the hose away from the hose

fitting.

4. Slide the fuel selector pin on the carburetor out towards the

back of the enclosure.

5. Replace the inlet hose and tighten the clamp securely.

6. On all other models, simply remove the air cleaner cover and

slide the fuel selector pin outward from the natural gas to the

LP position.

General Information

6

INSTALLING & CONNECTING GAS LINES

1. Both natural gas and LP Vapor are highly volatile substances,

so strict adherence to all safety procedures, codes, standards

and regulations is essential.

Gas line connections should be made by a certified plumber

familiar with local codes. Always use AGA-approved gas pipe

and a quality pipe sealant or joint compound.

Verify the capacity of the natural gas meter or the LP tank in

regards to providing sufficient fuel for both the generator and

other operating appliances.

2. Most applications will require an external manual shutoff valve

on the fuel line.

3. Where the gas line is to enter the generator, install a T-fitting

to allow for gas pressure monitoring. On one opening of the

fitting install a ¼” NPT nipple and threaded plug. In some

cases a sediment trap may also be installed.

4. When connecting the gas line to the generator, use the

provided section of UL Listed or AGA-approved flexible fuel

line in accordance with local regulations. The purpose of the

flexible fuel line is to ensure that vibration from the generator

does not cause a gas leak at one of the connection points, so

it’s important that the line be installed with as few bends as

possible.

5. Never bend the flexible fuel line to avoid using an elbow.

Bending the flexible line decreases its ability to absorb

vibrations and defeats its purpose as well as constricts the

actual fuel flow.

General Information

7

6. After checking for leaks, check the gas pressure at the

REGULATOR to make sure there’s enough gas pressure for

generator operation. See Owner’s Manual for fuel pressure

specifications. If not within these limits, contact your local gas

supplier.

7. When finished checking the gas pressure, close the manual

shutoff valve.

EXTERNAL ELECTRICAL CONNECTIONS

1. Drill a 1 ¾ inch hole and feed the conduit through the hole.

2. Remove the knockout in the back of the connection box, feed

the wires through the back of the box and secure the conduit

with the lock nut.

Seal the hole with silicone caulk. Don’t forget to caulk the hole

inside the house as well.

3. Mount the connection box so that it completely covers the hole in

the wall. Caulk around the sides and top of the box to ensure a good

seal.

Connect all wires to the lugs in the connection box (black to black,

red to red and white to white). Attach the green ground wire to

the ground screw and connect the two small plugs to their mating

receptacle ends.

General Information

8

4. Replace the protective cover plate and retaining screw, and

lock the connection box.

5. For 10-20 kW models, locate the metal hasp that is packaged

in the owner’s manual bag. Insert the hasp in the slot located

on the left side of the external circuit breaker box. Be sure that

the clip of the hasp is facing toward the front of the generator.

If desired, lock the external box.

GENERATOR ACTIVATION

When battery power is applied to the generator during the

installation process, the controller will light up. However, the

generator still needs to be activated before it will automatically run

in the event of a power outage.

Activating the generator is a simple one time process that is

guided by the controller screen prompts. Once the product is

activated, the controller screen will not prompt you again, even if

you disconnect the generator battery.

APPENDIX A – EZ SWITCH INSTALLATION &

OPERATIONAL TESTING

1. Before beginning any installation, make sure power is shut

OFF to the main distribution panel and carefully read the

Owner’s Manual that came with the transfer switch.

The distributed load center switch must be mounted close

enough to the main distribution panel to accommodate the

two-foot, pre-wired conduit. Make sure no water or corrosive

substances can drip onto the transfer switch enclosure.

2. Always inspect the switch for shipping damage. Never mount

a transfer switch that shows any evidence of damage.

3. Protect against impact and mount the switch vertically to

a rigid support structure. Make sure the switch is level and

plumb.

The transfer switch is an open transition switch. Open

transition switches prevent electrical feedback between the

generator and the utility by only allowing load circuits to be

connected to one power supply at a time.

4. Each wire in the pre-wired transfer switch is color-coded to

easily match circuits in the main panel to their new breakers

in the transfer switch.

5. When three-conductor wiring is used, two 120 volt circuits

will often share the same neutral wire. To avoid overloading

the neutral, either move BOTH of the circuits that share the

neutral or don’t move either of them.

6. When moving two circuits with a shared neutral, they should

be connected to adjacent positions (one above the other) in

the transfer switch. That will assure that the two hot wires

are on separate phases and will maintain their relationship to

neutral.

Appendix A

12

7. Choose a circuit to be backed up and remove the power lead

from the breaker.

8. Using UL Listed wire nuts, reconnect the power lead to a

matching breaker in the transfer switch.

9. Make sure each circuit moved is protected by the same

size breaker in the transfer switch. 15 Amp circuits must be

connected to 15 Amp breakers and 20 Amp circuits to 20

Amp breakers.

10. Connect the provided large neutral to the neutral bar in the

distribution panel.

11. Install a 2-pole breaker in the distribution panel to protect

the transfer switch. The required amp rating of the breaker

depends on which transfer switch is used. Pre-wired load

center switches the breaker cannot exceed 70 Amps. This

breaker must be compatible with the existing electrical

distribution panel.

Install the breaker in two adjacent empty slots (one above the

other) in the main panel.

12. When all priority circuits have been moved to the transfer

switch, close the main breaker to restore utility power and

make sure utility voltage at the transfer switch is correct.

Refer to NFPA 70-E for the safety equipment required when

working inside a live transfer switch.

Appendix A

1. Switch the generator’s main circuit breaker OFF and put the

mode switch in the OFF position.

2. Make sure utility power is OFF and place all of the priority

circuit breakers in the transfer switch in the OFF position.

3. Locate the transfer handle, insert the metal end into the slot

in the main contactor assembly and pull the handle DOWN to

move the main contacts to the standby power, or generator

position.

NEVER OPERATE THE TRANSFER SWITCH

MANUALLY WHEN LOADS ARE CONNECTED.

4. Put the generator’s mode switch in MANUAL to start the engine.

Allow the engine to warm up, then switch the generator’s

main breaker to the ON position. The generator is now

supplying electricity to the transfer switch but is not carrying

any load.

5. Be sure that voltage and frequency from the generator is

correct. If line-to-line voltage is not approximately 240

volts, refer to the Owner’s Manual for the proper adjustment

procedures. On all models, if line-to-neutral voltage is not 120

volts, check the neutral connection between the generator and

transfer switch.

Appendix A

14

6. When finished checking the voltage, switch the generator’s

main circuit breaker OFF and put the mode switch in the OFF

position to shut down the generator.

7. Make sure the 2-pole circuit breaker installed in the main

distribution panel is in the OFF position.

8. Use the transfer handle to move the main contacts in the

transfer switch to the UP (utility position). Switch the 2-pole

breaker ON in the distribution panel.

9. Now switch the generator’s main breaker ON, and put the

mode switch in AUTO.

10. Shut OFF utility power and make sure the generator starts

automatically.

11. If everything worked properly, switch the main breaker to ON

and make sure that power is automatically transferred back to

the utility.

12. After the engine has completed its cool down cycle and shut

down, shut OFF utility power again.

When the generator is supplying power to the transfer switch,

move the breakers in the switch to the ON position, one at a

time, until the generator has accepted the entire priority load.

13. With the generator carrying the entire priority load, recheck

gas pressure to verify that it is at the same level it was before

the generator was started.

NOTE:

Even if the generator is running smoothly at

this point, a drop in gas pressure indicates that

the supply is barely adequate to supply the

generator’s needs. Changes in the generator load,

or additional gas demand by other appliances

may affect the generator’s performance. Verify

gas pressure and pipe sizing.

Unhook the

manometer and reinstall the port plug.

Appendix A

15

14. Switch the main breaker ON to restore utility power.

The generator will continue to run to allow the engine to cool

down before shutting itself off.

Shut off utility power again. The generator should start and the

entire priority load should transfer to the generator.

Close the main breaker to restore utility power and allow the

engine to cool down and shut itself off.

15. Operational tests are now complete. Refer to – Setting the

Automatic Exercise Function to complete the installation.

APPENDIX B – RTSX AND RTSD TRANSFER

SWITCH INSTALLATION & OPERATIONAL

TESTING

1. Before beginning any installation, make sure power is shut

OFF to the main distribution panel and carefully read the

Owner’s Manual that came with the transfer switch.

To simplify the installation process, the transfer switch

should be mounted as close to the main distribution panel as

possible. Make sure no water or corrosive substances can

drip onto the transfer switch enclosure.

2. Always inspect the switch for shipping damage. Never mount

a transfer switch that shows any evidence of damage.

3. Protect against impact and mount the switch vertically to a rigid

support structure. Make sure the switch is level and plumb.

Check local codes before wiring the transfer switch. Some

jurisdictions require that wiring inside the switch be done by a

licensed electrician.

4. All wiring must be the correct size and type, and must

conform to all codes, standards and regulations. Refer to the

transfer switch Owner’s Manual and the National Electrical

Code for additional information.

Appendix B

16

5. As with any product, design changes can occur over time, so

always refer to the schematics in the transfer switch Owner’s

Manual for the required connections and safety precautions.

6. The transfer switch being used is an open transition switch.

Open transition switches prevent electrical feedback between

the generator and the utility by only allowing load circuits to

be connected to one power supply at a time.

SELECTED CIRCUIT COVERAGE

1. The generator powers only designated circuits that are grouped

together and wired into a separate priority distribution panel.

The transfer switch is installed between the main distribution

panel and the priority panel.

The amperage rating of the transfer switch must be equal to

or greater than the highest amperage rating of the utility and

generator breakers feeding the switch.

WHOLE-HOUSE CIRCUIT COVERAGE

1. The generator will be backing up all electrical loads within the

panel, so the amperage rating of the transfer switch must be

equal to or greater than the amperage rating of the normal

utility service.

Unless a service rated transfer switch is used, a main service

disconnect must be located before the transfer switch. The

transfer switch must be installed between the utility service

entrance and the building distribution panel.

2. A service rated transfer switch is installed between the

service and the main distribution panel. The service rated

switch becomes the main service so no service disconnect is

needed. The existing main distribution panel becomes a sub-

panel.

Appendix B

17

3. The grounding that is normally in the main panel must be

accomplished in the service rated switch and must be

disconnected in the existing distribution panel. Refer to the

National Electrical Code (NEC) for complete information on

grounding and bonding.

ELECTRICAL CONNECTIONS

1. Connect the power leads from both the generator and the

utility to the appropriate lugs in the transfer switch. The lugs

are clearly marked in the switch.

N = Normal Utility Supply

E = Generator Connection Panel

T = Load Distribution Panel

2. Neutral wires from both the utility and the generator are

connected to the same neutral lug in the switch.

3.

Connect the control wires from the generator to the designated

locations. Wires 0, 23 and 194 connect to the terminal strip; N1,

N2, and T1 connect directly to the fuse holders.

4. Complete the transfer switch wiring by connecting the

equipment ground wires from both the utility and the

generator to the ground lug.

5. Being careful to support the lugs, torque the lugs in the

transfer switch to the specifications shown on the transfer

switch. Decal located on the inside of the switch door.

OPERATIONAL TESTING

1. If installing the RTSD switch, the service was changed so make

sure the terminations are good before re-energizing the utility.

Appendix B

18

2 Switch the main utility breaker OFF. Refer to NFPA 70-E for the

safety equipment required when working inside a live transfer

switch.

3. Energize the utility and check line-to-line and line-to-neutral

voltage at terminals N1 and N2 on the transfer contactor. If

line-to-line voltage is not approximately 240 volts, de-energize

utility power and check the terminations between the utility

and N1 and N2.

If line-to-neutral voltage is not approximately 120 volts, de-

energize utility power and check the neutral terminations.

Repeat the same voltage checks on terminals T1 and T2 to

make sure current is flowing properly through the contactor.

4. Switch the generator’s main circuit breaker OFF and put the

mode switch in the OFF position.

5. Make sure utility power is OFF and place all of the individual

circuit

breakers in the main distribution panel in the OFF position.

6. Locate the transfer handle, insert the metal end into the slot in

the main contactor assembly. Pull the handle DOWN to move

the main contacts to the standby power (generator) position.

NEVER OPERATE THE TRANSFER SWITCH MANUALLY WHEN

LOADS ARE CONNECTED.

7. Put the generator’s mode switch in MANUAL to start the engine.

Allow the engine to warm up, then switch the generator’s main

breaker to the ON position. The generator is now supplying

electricity to the transfer switch but is not carrying any load.

8. Check to be sure that voltage and frequency from the

generator is correct. If line-to-

line voltage is not approximately

240 volts, refer to the generator

Owner’s Manual for the

proper adjustment procedures. If line-to-neutral voltage is

not approximately 120 volts, check the neutral connection

between the generator and transfer switch.
