CAUTION – PERSONAL DANGER
CAUTION - NEVER dispose of a battery in a fire. The battery is
capable of exploding.
CAUTION - DO NOT open or mutilate the battery. Released
electrolyte is known to be harmful to the skin and eyes and to be
very toxic.
These engine generator sets are all NEGATIVE ground. Be very
careful not to connect the battery in reverse polarity, as this may
short circuit the battery charging system on the engine.
CAUTION – A battery presents a risk of electrical shock and high
short circuit current. The following precautions must be observed
when working with batteries.
1. Remove watches, rings and other metal objects.
2. Use tools with insulated handles.
3. Check both the battery cable ends and the battery posts to be
sure they are free of corrosion.
4. Always connect the battery positive cable first and then
connect the battery negative cable. When removing the
battery cables from the battery reverse the procedure,
disconnect the negative cable first and then the positive
cable.
5. Be sure all connections are tight and coat the terminals and
cable end with dialectic grease.
WARNING – The electrolyte is a diluted sulfuric acid that is harm-
ful to the skin and eyes. It is electrically conductive and corrosive.
The following precautions must always be taken.
* Always wear full eye protection and protective clothing.
* Where electrolyte contacts the skin, wash off immediately
with water.
* If electrolyte contacts the eyes, flush thoroughly and immed-
iately with water and seek immediate medical attention.
* Spilled electrolyte is to be washed down with an acid neutral-
izing agent. A common practice is to use a solution of one
pound of bicarbonate of soda (baking soda) to one gallon 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.
DANGER – Explosive Fire Risk
* Never smoke when near batteries.
* Do not cause a flame or spark in the battery area.
* Always discharge static electricity from your body before
touching batteries by first touching a grounded metal surface.
SERVICING BATTERIES
Batteries used on these units may over time lose water. This is
especially true if you are using a trickle charger to maintain your
battery. When refilling the battery with water use only distilled
water. Tap water will shorten the service life of the battery.
Never fill the battery above the fill line. Over filling above the
upper level line may cause the electrolyte to overflow, resulting in
corrosion to the engine or nearby parts. Immediately wash off any
spilled electrolyte following the procedure above.
NOTE: Always make sure that a new battery is fully charged
before installing it on a generator set. Failure to do so can cause
damage to the engine control module in the generator set.
All connections must be clean and tight. Check the electrolyte
(fluid) in the battery periodically to be sure it is above the plates.
Never allow the battery to remain in a discharged condition.
CONNECTING THE BATTERY CHARGER &
BLOCKHEATER
A two-stage battery tender is provided on all standby generators.
This battery tender charges at a rate of 750 mA until the battery is
fully charged and then automatically switches to a 13.2 VDC float
charger. The charger has an indicator light on it, red indicates it
is charging, and green indicates it is in the storage mode (float
charge). This charger is mounted on the engine generator set just
below the engine control panel.
** NOTICE **
The trickle charger is not intended to recharge a battery which has
become completely discharged. It is designed to produce just
enough current to maintain a fully charged battery.
The battery tender receptacle is to be powered by a GFCI circuit
and installed in accordance with the United States National
Electric Code. These AC wires can be run in the same conduit as
the other AC leads from the generator. It is suggested that this
circuit be fused for 15 amps, then both the battery charger and
the block heater can be connected to the same circuit. A 120 volt
duplex receptacle is mounted on the generator along side circuit
breaker panel, the battery tender is shipped already plugged into
the receptacle.
The engine blockheater installed on this unit should also be
plugged in this receptacle. The block heater is thermostatically
controlled and when plugged in will maintain the engine coolant
temperature between 100 and 120 degrees F.

FIRE HAZARD - All wiring must be done by a licensed electrician,
and must conform to the national electrical code and comply with
all state and local codes and regulations. Check with the local
authorities before proceeding!
INSTALLATION NOTES
Because of the many different types of service, feeder, and distri-
bution equipment, no specific wiring instructions can be provided.
It is recommended that only copper wire be used. In all cases it is
essential that while the load is connected to the generator, there
can be absolutely no feedback from the generator to the power
line or the power line to the generator. When properly installed,
the normal A.T.S. Control and safety systems will eliminate all
paths for feedback.
