1.9 BATTERY INSTALLATION
DANGER

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.

Do not dispose of the battery in a fire. The bat-
tery 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.


The electrolyte is a dilute sulfuric acid that is
harmful to the skin and eyes. It is electrically
conductive and corrosive. The following proce-
dures are to be observed:
• Wear full eye protection and protective 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
medical attention, and
• 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) bicarbon-
ate 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.

Lead acid batteries present a risk of fire because
they generate hydrogen gas. The following pro-
cedure are to be followed:
• DO NOT SMOKE when near batteries,
• DO NOT cause flame or spark in battery area, and
• Discharge static electricity from body before touch-
ing batteries by first touching a grounded metal
surface.
Servicing of batteries is to be performed or super-
vised by personnel knowledgeable of batteries and
the required precautions. Keep unauthorized person-
nel away from batteries.
For recommended batteries, see the “Specifications”
section in the Owner’s Manual. All batteries must
be at 100 percent state-of-charge before they are
installed on the generator.
When using maintenance-free batteries, it is not nec-
essary to check the specific gravity or electrolyte level.
Have these procedures performed at the intervals
specified in the “Maintenance” section in the Owner’s
Manual. A negative ground system is used. Battery
connections are shown on the wiring diagrams. Make
sure all batteries are correctly connected and termi-
nals are tight. Observe battery polarity when connect-
ing batteries to the generator set.
NOTE:
Damage will result if the battery connections are
made in reverse.
2.2 UNPACKING
Carefully unpack the transfer switch. Inspect closely
for any damage that might have occurred during
shipment. The purchaser must file with the carrier
any claims for loss or damage incurred while in tran-
sit.
Check that all packing material is completely removed
from the switch prior to installation.
Attach any lifting device to the transfer switch
mounting holes or brackets only. DO NOT LIFT THE
SWITCH AT ANY OTHER POINT.
