and with the unit. The generator can operat e safely, effi-

ciently and reliably only if it is properly installed, ope rated and

m

aintained. Many accidents are caused by failing to foll ow si

m

ple

and funda

m

ent al rules or precautions.

The

m

anufacturer cannot anticipate every possible circu

m

stance

that

m

ight involve a hazard. The wa rning s in this

m

anual, and on

tags and decals affixed to the unit are, therefore, not all-inclusive. If

using a procedure, work

m

ethod or operating technique the

m

anu-

facturer do es not specifically reco

mm

end, ensure that it is safe for

ot hers. Also

m

ake sure the procedure, work

m

ethod or operating

technique utilized does not render the generator unsafe.

DANGER



Despite the safe design of this generator,

operating this equipment imprudently, neglecting

its maintenance or being careless can cause

possible injury or death. Permit only responsible

and capable persons to install, operate and main-

tain this equipment.

during operation. Exercise care near running

generators.



Installation must always comply with applicable

codes, standards, laws and regulations.



A running generator gives off carbon monoxide,

and odorless, colorless poison gas. Breathing in

carbon monox ide can cause headaches, fatigue,

di ziness, nausea, vomitting, confusion, fainting,

siezures or death.



If this generat or is used to power electrical load

circuits normally powered by a utility power

source, it i s 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 i n damage to the gen-

erator and also may result in injury or death to

utility power workers due to backfeed of electrical

energy.

1.3 NEC REQUIREMENT FOR ARC FAULT

CIRCUIT INTERRUPTION BREAKER FOR

BEDROOMS

In 2001, the

N

ational Electric Code

(

N

EC

)

introduced a require

m

ent

for new construct ion. This new require

m

ent indicates the nee d for

Arc Fault Circuit Interrupters to be used to protect the co

m

plete

branch circuit that feeds a dwelling bedroo

m

. The actual

N

EC

require

m

ent is ind icate d b elow.

1.3.1 SECTION 210.12 ARC FAULT CIRCUIT INTER- 

RUPTER PROTECTION

1.

D

efinition: An arc fault circ uit i nterrupt er is a device intended

to provide protection fro

m

the effects of arc fault s by recog-

nizing characteristics unique to arcing and by functioning to

de-energize the circuit when an arc fault is detected.

2.

D

welling

U

nit Bedroo

m

s: All branch circuits that supply 125

volt , single-phase, 15 and 20 a

m

pere outlets installed in

dwelling unit bedroo

m

s shall be protected by an arc fault cir-

c uit interrupter listed to provi de protection of the entire branch

cir cuit.

S

ection 210.12 requires that AFCI protect ion be provided on branch

cir cuits that supply outlets

(

receptacle, lighting, etc.

)

in dwell-

ing bedroo

m

s. The require

m

ent is li

m

ited to 15 and 20 a

m

pere,

125 volt circuit s. There is no prohibition against providing AFCI

protection on other circuits or in locations oth er than b edroo

m

s.

Because circuits are often shared between a bedroo

m

and other

areas such as closets and hallways, providing AFCI protection on

the co

m

plete circuit would co

m

ply with 210.12.

If during the installation of the ho

m

e standby syste

m

the decision

is

m

ade to provi de back up power to a bedroo

m

branch circuit,

then the circuit breaker in the transfer switch should be replaced

with an Arc Fault Circui t Int errupter.

It is

m

ost i

m

por tant that breakers only be switched like for like.

For instance, if replacing a 15A breaker, it M

U

S

T be replaced wi th

a 15A AFCI breaker.

L

ikewise, a 20A breaker M

U

S

T be replaced

with a 20A AF CI.

These AFCI breakers are available at the nearest hardware store.

P ga s. Ask the fuel supplier for the Btu content of

the fuel.

R

eq uired fuel pressure for natural gas is five (5) inches to seven

(7) inches water column (0.18 to 0.25 psi); and for liquid pro-

pane, 10 inches to 12 inches of water column (0.36 to 0.43 psi).

The primary regulator for the propane supply is NOT INCLUDED

with the generator.

NOTE:

All pipe sizing, construction and layout must comply

with NFPA 54 for natural gas applications and NFPA

58 for liquid propane applications. Once the genera-

t or is installed, verify that the fuel pressure NEVER

drops below four (4) inches w ater column for natural

gas or 10 inches water column for liquid propane.

Prior to install ation of the generator, the installer should consult

loca l fuel suppliers or the fire

m

arshal to check codes and regula-

tions for proper installation.

L

ocal codes will

m

andate correct rout-

ing of gaseous fuel line piping around gardens, shrubs and other

landscaping to prevent any d a

S

pecial considerations should be given when installing the unit

where local conditions include flooding, torn ados, hurricanes,

ear thquakes a nd unstable ground for the flexibility and strength of

piping and their connecti ons.

DANGER



Gaseous fuels such as natural gas and liquid

propane (LP) gas are highly explosive. Even the

slightest spark can ignite such fuels and cause

an explosion. No leakage of fuel is permitted.

Natural gas, which is lighter than air, tends to

collect in high areas. LP gas is heavier than air

and tends to settl e in low areas.

NOTE:

A minimum of one approved manual shut-off valve

must be installed in the gaseous fuel supply line. The

valve must be easily accessible. Local codes deter-

mine the proper location.

DANGER



The engine exhaust fumes contain carbon mon-

ox ide, whi ch can be DEADLY. This dangerous

gas, if breathed in sufficient concentrations,

can cause unconsciousness or even death. This

generator must be instal led properly, in strict

compliance with applicable codes and stan-

dards. Following installation, do nothing that

might render the system unsafe or in noncom-

pliance with such codes and standards.

• Operate the generator outdoors ONLY.

• Keep exhaust gases from ent ering a confined

area through windows, doors, ventilation, crawl

spaces or other openings (Figure 1.9).

• Generac Power Systems as a responsible manu-

facturer highly recommends that carbon monox-

ide detector(s) be installed indoors according to

the manufacturer

'

s instructions/recommendations.

• The generator must me mounted safely per appli-

cable codes and the manufacturer

'

s specifica-

tions. Do NOT alter or add to the exhaust syst em,

or do anything that might render the exhaust sys-

tem unsafe or in noncompliance with applicable

codes and standards.

ind, the

m

anufacturer contracted with an inde pendent

testing laboratory to run full sca le fire tests to assure that the

Eaton enclosure woul d not ignite co

m

bustible

m

aterials outside

the enclosure.

The criteria was to d eter

m

ine the worst ca se fire scenario within

the generator and to deter

m

ine the ignitability of ite

m

s outside

the engine enclosure at various distances. The Eaton enclosure

is constructed of non-co

m

m

aterials and the results and

c onclusi ons fro

m

the independent testing lab indicated that any

fire within the generator enclosure would not pose any ignition risk

to nearby co

m

bustibles or structures, with or without fire service

personnel response.

Based on this testing and the require

Figure 1.11 – Battery Cable Connections

NOTE:

Dielectric grease should be used on battery posts to

aid in the prevention of corrosi on.

NOTE:

Damage will result if battery connec ti ons are made

in reverse.

NOTE:

In areas where temperatures regularly fall below 10

°

F (-12

°

C) it is recommended that a pad type battery

heater be installed to aid in cold climate starting.

1.14 THE BATTERY

DANGER



Do not dispose of the battery in a fire. The

battery is capable of exploding.



A battery presents a risk of electrical shock

and hi gh short circuit current. The following pre-

cautions are to be observed when working on

batteries:

• Remove the 7.5A fuse from the generator control

panel.

• Remove watches, rings or other metal objects;

• Use tools with insulated handles;

• Wear rubber gloves and boots;

• Do not lay tools or metal parts on top of the

battery; and

• Disconnect charging source prior to connecting or

disconnecting battery terminals.



Do not open or mutilate the battery. Released

electrolyte has been known to be harmful to the

skin and eyes, and to be toxic.



The electrolyte is a dilute sul furic acid that is

harmful to the skin and eyes. It is electrically

conductive and corrosive.

The following procedures are to be observed:

• Wear full eye protection and prot ective clothing;

• Where electrolyte contacts the skin, wash it off

immediately with water;

• Where electrolyte contacts the eyes, flush thor-

oughly and immediately with water and seek medi-

cal attention; and

• Spilled electrolyte is to be washed down wi th an

acid neutralizing agent. A common practice is to

use a solution of 1 pound (500 grams) bicarbonate

of soda to 1 gallon (4 liters) of water. The bicar-

bonate of soda solution is to be added until the

evidence of reaction (foaming) has ceased. The

resulting liquid is to be flushed with water and the

area dried.



Lead-acid batteries present a risk of fire

because they generate hydrogen gas. The fol-

lowing

procedures are to be followed:

• DO NOT SMOKE when near the battery;

• DO NOT cause flame or spark i n battery area; and

• Discharge static electricity from body before

t ouching the battery by first touching a grounded

metal surface.

Section 1 — General Information

Air-cooled Generators



Be sure the AUTO/OFF/MANUAL switch is set to

the OFF position before connecting the battery

cables. If the switch is set to AUTO or MANUAL,

the generator can crank and start as soon as

the battery cables are connected.



Be sure the utility power supply is turned off

and the 7.5A fuse is removed from the generator

control panel, or sparking may occur at the bat-

tery posts as the cables are attached and cause

an explosion.

S

ervicing of the battery is to be per for

1.15 BATTERY CHARGER

NOTE:

These generators DO NOT contain an internal battery

charger.

NOTE:

The manufacturer provides a battery trickle charger

that is active when the unit is set up for automatic

operation. With the battery installed and ut ility power

source voltage available to the transfer switch, the

battery recei ves a trickle charge to prevent self-

discharge. The trickle charger is designed to help

extend the life of the battery by maint aining the bat-

tery. The trickle charge feature cannot be used to

recharge a discharged battery.

A separate bat tery charger

m

odule is included with the generator.

removed to adjust the voltage regulator.

NOTE:

The voltage regulator is housed behind the genera-

t or

'

s control panel. The regulator maintains a voltage

in direct proportion to frequency at a 2-to-1 ratio. For

example, at 60 Hertz, line-to-neutral vol tage will be

124 volts.

With the switch set to AUTO, the engine may

crank and start at any time without warning.

Such automati c starting occurs when utility

power source voltage droops below a preset

level or during the normal exercise cycle. To

prevent possible injury that might be c aused

by such sudden starts, always set t he switch to

OFF and remove the fuses before working on or

around the generator or transfer switch. Then,

place a “DO NOT OPERATE” tag on the genera-

t or panel and on the transfer switch.
