See the Important Safety Instructions section for complete battery-related
safety information.
The generator set requires a 12V battery (negatively grounded) for engine cranking
and powering the electronic control system. When the generator set is running, the
battery is charged from the engine-driven battery alternator. When the set is not
running, an AC powered battery charger is needed to keep the battery charged.
As part of the installation, make sure that the battery is secured to the battery tray
with the strap provided.
To connect the battery:
1. Connect the positive battery terminal.
2. Connect the negative battery terminal.
3. Make sure that the black and red battery cable boots are in place.
Refer to the Model Specifications section for battery specifications.
An optional thermostatically controlled battery heater is available for more reliable
starting.
To prevent injury due to accidental startup:
• Do not connect the battery cables to the battery until the installation has been
completed;
• Make sure tools, rags, and body parts are kept away from any rotating parts or
electrically live parts; and
• Make sure it is time to start the generator set.
