battery negative cable. When removing the battery cables from the
battery, reverse the procedure and disconnect the negative cable
first and then the positive cable.
5. Be sure all connections are tight and coat the terminals and cable
ends with dielectric grease.
WARNING:
The electrolyte is a 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 immediately and thoroughly
with water. 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
biocarbonate of soda (baking soda) to one gallon of water. The
biocarbonate of soda 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 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 ground 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 electrolyte to overflow, resulting in corrosion to
the engine or nearby parts. Immediately wash off any spilled electrolyte
following the procedure above.
BATTERY CHARGING
This generator is equipped with an engine mounted alternator that will
recharge the battery during operation. It is not necessary to have the
battery charger circuit on the emergency distribution circuit.
CAUTION: EQUIPMENT DAMAGE:
Always connect the positive cable first and the negative cable last.
When disconnecting, remove the negative cable first and the positive
cable last. Failure to connect and disconnect in the proper sequence
can cause equipment damage.
Observe polarities: connect the positive (+) battery terminal to the
(+) cable from the engine starter; the negative (-) battery terminal is
connected to the negative cable (ground) from the engine generator
assembly. 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 discharge condition.
CAUTION: EQUIPMENT DAMAGE:
NEVER JUMP START
these units. Doing so will destroy the engine
control module, rendering the unit non-operational. Remove and fully
recharge the battery before attempting to start.
CONNECTING THE BATTERY CHARGER & BLOCK
HEATER
A three-stage battery charger is provided standard for all 12 volt
standby systems. The standard charger is an Automatic Battery
Charger & Maintainer. This Charger has three rates of charging.
During the first stage, know as BULK Charging, the charging current
is limited to 2 Amps at a voltage of up to 14.5 volts. The green LED
will blink during this stage. During stage two, know as ABSORPTION
Charging, the charging voltage is held at 14.5 volts and the charging
rate gradually reduces the amount of current (amps) flowing to the
battery. The green LED will also blink during this stage. Stage three
is called MAINTENANCE Charging. During this stage the voltage will
drop to 13.3 volts and the charge rate will drop to as low at .1 amps.
This keeps your batteries in a fully charged condition without over
charging them. During this stage the green LED is constantly lit. There
are optional 5 and 10 amp chargers available that may be installed on
some units
The block heater is thermostatically controlled and when plugged in
will maintain the engine coolant temperature between 100 and 120
degrees F.
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 and block heater are powered by a customer
supplied 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 20 amps when the block heater and battery
charger are on shared circuits and two 15 amp circuits when they
are split. Splitting the battery charger and block heaters circuits are
advantageous that if one of the components fail in a manner causing
the breaker to trip the other component will be unaffected and continue
operating normally.
The block heater and battery charger are both hard wired into a
terminal block located in the AC wiring cabinet.
