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.
WARNING
The electrolyte is diluted sulfuric acid that is harmful
to the skin and eyes. It is electrically conductive and
corrosive. The following precautions must always be
taken.
1. Always wear full eye protection and
protective clothing.
2. Where electrolyte contacts skin, wash off
immediately with water.
3. If electrolyte contacts the eyes, flush
thoroughly and immediately with water
and seek immediate medical attention.
4. Spilled electrolyte is to be washed down
with an acid neutralizing 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.
All connections must be clean and tight. Check the
electrolyte in the battery periodically to be sure it is
above the plates. Never allow the battery to remain in a
discharged condition.
BATTERY CHARGER & BLOCK HEATER
BATTERY CHARGER
A three-stage, on-board marine battery charger is provided
standard on this unit. The charger is a 5 amp dual use
maintainer and charger designed to keep your batteries
fully charged by maintaining them automatically.
Make sure all DC battery connections are tight and clean.
Follow battery manufacturer’s recommendations.
This charger is mounted under the customer connection
on the control side of the generator. The charger will
need to be plugged to a customer’s power source, using
a customer supplied heavy duty, UL approved extension
cord. The receptacle is to be powered by a GFCI circuit and
installed in accordance to the US National Electric Code. It is
suggested that this circuit be fused to 20 Amps.
Low/Charge Mode:
The illuminated blue power LED and red low/charging LED.
This indicates the Low/Charge mode is in process. When
completed the RED Low/Charge LED will turn off.
Auto Maintain Mode:
The illuminated Green auto maintain LED. This indicates
your 12 volt battery is fully charged. During short or long
term storage periods, Auto Maintain (Energy Saver) mode
will monitor and auto maintain a battery only when needed
to maintain a full state of charge. This feature significantly
reduces AC Power consumption, lowers operating costs
and maximizes reserve power performance.
BLOCK HEATER
The block heater on this unit is a 1000 watt heater and
can use the same 20 Amp GFCI fused circuit. The circuit
will terminate on the 120 Volt terminal block mount in the
customer connection cabinet. The engine block heater
installed on this unit should also be plugged into this
receptacle. The block heater is thermostatically controlled
when plugged in will maintain the engine coolant
temperature between 100 and 120 degrees F.
INSTALLING THE BATTERY
A customer supplied 12 Volt battery is required to complete
the installation. Installation of the highest CCA rated battery,
within the correct BCI group, will increase cold weather
starting performance.
BATTERY REQUIREMENTS
Voltage BCI Group Min. CCA Rating
12 24 650
Installation and servicing of batteries must only be
preformed or supervised by personnel knowledgeable of
batteries and the required precautions. Keep unauthorized
personnel away from batteries.
When installing or replacing batteries, use the proper
group/size starting battery. The battery should be a
maintenance-free lead acid design. Deep cycle batteries will
not work for this application.
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
In the following battery installation procedure, check
to be sure the engine control is in the “stop” position.
This should be your last step before initial start-up.
WARNING: EQUIPMENT DAMAGE
This unit is12 Volt and is negative ground. Permanent
damage will occur if they are connected to a 24 Volt
system or a positive ground system. If you are using
the truck batteries to start these units, you may
have to disable the charging system to keep it from
interfering with the vehicle charging system.
CAUTION: PERSONAL DANGER
NEVER dispose a battery in a fire. The battery is
capable of exploding.
DO NOT open or mutilate the battery. Released
electrolyte is known to be harmful to the skin and
eyes and to be very toxic.
DANGER: EXPLOSIVE FIRE RISK
1. Never smoke when near batteries.
2. Do not cause a flame or spark in the
battery area.
3. Always discharge static electricity from
your body before touching batteries by first
touching a ground metal surface.
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 first and then the
positive cable.
5. Be sure all connections are tight and coat
the terminals and cable ends with dialectic
grease.
