Battery
The generator set requires a 12V battery for engine cranking and powering the
electronic control system. When the generator set is running, the battery is charged
from the engine-driven battery charger. When the generator set is not running, an
AC powered battery charger is provided to keep the battery charged.
WARNING
To avoid injury, wear proper safety protection when working around
batteries. Keep open flames and sparks away from the equipment.
WARNING
Automatic startup of the generator set during installation can cause severe
personal injury or death. Make sure the generator set is shut down and
disabled:
1. Press the generator set's red STOP button on the local display to stop
the generator set. Allow the generator set to thoroughly cool to the
touch.
2. Turn off and disconnect the battery charger from the AC source before
disconnecting the battery cables.
3. Disconnect the negative (–) cable from the battery and secure it from
contacting the battery terminals to prevent accidental starting.
To connect the battery:
1. Connect the battery cables to the battery with the positive (+) cable first.
Immediately cover the battery post and terminal with the red terminal cover
provided on the battery cable.
2. Connect the negative (-) cable to the battery's minus terminal.
Refer to the Model Specifications section for battery specifications.
An optional thermostatically controlled battery heater is available for more reliable
starting.
