OPM-134/B
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.
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.
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
first and then the positive cable.
5. Be sure all connections are tight and coat the
terminals and cable ends with dialectic grease.
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.
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.
SERVICING BATTERIES
CAUTION: EQUIPMENT DAMAGE
Voltage spikes can damage the DC control circuits.
Disconnect the battery charger from the AC power
source prior to disconnecting the battery.
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. Different types of batteries
require various types of maintenance. Refer to the battery
manufacturer for specific recommendations.
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. Depending on
your battery type, 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.
CONNECTING BATTERY CHARGER &
BLOCK HEATER
A three-stage battery charger is provided standard on
this unit. The charger is an Automatic Battery Charger &
Maintainer. This charger has three rates of charging. During
the first mode, known as Bulk charging, the charging
current is limited to 5 Amps at a voltage of up to 14 Volts.
The yellow LED will be on constantly during this stage.
When the charging rate drops to 2.5 Amps, the charge will
enter the ABSORPTION charging mode. During this mode,
the yellow LED will be flashing. The charging voltage is
held at 14 Volts and the charging rate gradually reduces
the amount of current (Amps) flowing to the battery to
100% charged state. The battery can be left on this mode
indefinitely. During this mode, the green LED will be on
constantly.
This charger is mounted under the customer connection on
the control side of the generator and hard wired to the AC
connection.
The block heater on this unit is a 1800 watt heater and
is hard wired to the AC connection. The block heater is
thermostatically controlled and will maintain the engine
coolant temperature between 100 and 120 degrees F.
MOUNTING THE TRANSFER SWITCH
WARNING: FIRE HAZARD
All wiring must be done by a licensed electrician, and
must conform to the National Electrical Code and
comply with all the local codes and regulations. Check
with the local authorities before proceeding.
INSTALLATION NOTES:
Because of many different types of service, feeder and
distribution 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
