Battery gases. Explosion can cause severe injury or
death. Battery gases can cause an explosion. Do not smoke
or permit flames or sparks to occur near a battery at any time,
particularly when it is charging. Do not dispose of a battery in a
fire. To prevent burns and sparks that could cause an
explosion, avoid touching the battery terminals with tools or
other metal objects. Remove all jewelry before servicing the
equipment. Discharge static electricity from your body before
touching batteries by first touching a grounded metal surface
away from the battery. To avoid sparks, do not disturb the
battery charger connections while the battery is charging.
Always turn the battery charger off before disconnecting the
battery connections. Ventilate the compartments containing
batteries to prevent accumulation of explosive gases.
Battery short circuits. Explosion can cause severe injury
or death. Short circuits can cause bodily injury and/or
equipment damage. Disconnect the battery before generator
set installation or maintenance. Remove all jewelry before
servicing the equipment. Use tools with insulated handles.
Remove the negative (--) lead first when disconnecting the
battery. Reconnect the negative ( --) lead last when
reconnecting the battery. Never connect the negative (--)
battery cable t o the positive (+) connection terminal of the
starter solenoid. Do not test the battery condition by shorting
the terminals together.
Use a 12-volt battery with a minimum rating of 675 cold
cranking amps at 0 _F. The generator set uses a
negative ground with a 12-volt engine electrical system.
See Figure 6-9 for battery connections. Make sure that
the battery is correctly connected and the terminals are
tight.
Note: The generator set will not start and circuit board
damage may occur if the battery is connected in
reverse.
Figure 6-10 shows the location of the engine starting
battery. Standard battery cables provide easy
connection to the battery. Use the following procedure
to install and connect the battery.

Battery Installation Procedure
1. Ensure that the starting battery is fully charged
before placing the battery in service.
2. Clean the battery posts and/or adapters if
necessary.
3. Install the battery post adapters, if needed.
4. Place the battery in the housing.
5. Verify that the controller master s witch is in the OFF
position.
6. Connect the positive (+) lead to the engine starting
battery.
7. Connect the negative (--) lead to the engine starting
battery.
Refer to Section 3.8 for battery maintenance
instructions.
6.8.4 Battery Charger
Generator sets that are not exercised regularly require
an external battery charger to keep the starting battery
fully charged. Obtain a battery charger from your
generator set supplier. Observe the battery polarity
when connecting the battery charger. Plug the battery
