BATTERY INSTALLATION
Standby generators installed with automatic
transfer switches will crank and start automati-
cally when NORMAL (UTILITY) source voltage is
removed or is below an acceptable preset level.
To prevent such automatic start-up and pos-
sible injury to personnel, do not connect battery
cables until certain that normal source voltage
at the transfer switch is correct and the system
is ready to be placed into operation.
Storage batteries give off explosive hydrogen
gas. This gas can form an explosive mixture
around the battery for several hours after charg-
ing. The slightest spark can ignite the gas and
cause an explosion. Such an explosion can shat-
ter the battery and cause blindness or other
injury. Any area that houses a storage battery
must be properly ventilated. Do not allow smok-
ing, open flame, sparks or any spark producing
tools or equipment near the battery.
Battery electrolyte fluid is an extremely caus-
tic sulfuric acid solution that can cause severe
burns. Do not permit fluid to contact eyes, skin,
clothing, painted surfaces, etc. Wear protective
goggles, protective clothing and gloves when
handling a battery. If fluid is spilled, flush the
affected area immediately with clear water.
Spilled electrolyte is to be washed down with
an acid neutralizing agent. A common practice
is to use a solution of one pound (500 grams)
bicarbonate of soda to one gallon (4 liters) of
water. The bicarbonate 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.
Do not dispose of the battery in a fire. The
battery is capable of exploding.
Do not open or mutilate the battery. Released
electrolyte can be toxic and harmful to the skin
and eyes.
The battery represents a risk of high short circuit
current. When working on the battery, always
remove watches, rings or other metal objects,
and only use tools that have insulated handles.
When replacing batteries, use the same number and
type of battery (see "Specifications"). All batteries
must be at 100 percent state-of-charge before they
are installed on the generator.

DANGER
When using maintenance-free batteries, it is not
necessary to check the specific gravity or electrolyte
level. Have these procedures performed at the inter-
vals specified in Section 4, "Maintenance." A nega-
tive ground system is used. Battery connections are
shown on the wiring diagrams. Make sure all batter-
ies are correctly connected and terminals are tight.
Observe battery polarity when connecting batteries to
the generator set.
Damage will result if the battery connections are
made in reverse.

PREPARATION BEFORE START-UP
The instructions in this section assume that the
standby generator has been properly installed, ser-
viced, tested, adjusted and otherwise prepared for
use by a competent, qualified installation contractor.
Be sure to read the "Safety Rules" on Pages 2 and 3,
as well as all other safety information in this manual,
before attempting to operate this (and related) equip-
ment.
2.9.1 PRIOR TO INITIAL START-UP
Prior to initially starting the generator, it must
be properly prepared for use. Any attempt to
crank or start the engine before it has been
properly serviced with the recommended types
and quantities of engine fluids (oil, coolant, fuel,
etc.) may result in an engine failure.
Before starting the generator for the first time, the
installer must complete the following procedures. For
follow-up maintenance information and/or service
intervals, please refer to "Maintenance" section and
the "Service Schedule".
2.9.1.1 Transfer Switch
If this generator is used to supply power to any elec-
trical system normally powered by an electric utility,
the National Electrical Code requires that a transfer
switch be installed. The transfer switch prevents elec-
trical backfeed between two different electrical sys-
tems. (For additional information, see the applicable
transfer switch manual for this unit.) The transfer
switch, as well as the generator and other standby
components, must be properly located and mounted
in strict compliance with applicable codes, standards
and regulations.
