OPERATING THE DIESEL GENERATOR
2-7.4 DC application
Both DC terminals provide output: 12VDC, 7A. The red terminal is "+"(positive)
pole of power supply. It can be used as load for rated voltage 12VDC and also
used for charging 12V battery.
1. In case to charge the battery with two lead connect to the start circuit, the
negative lead should be disconnected form the generator.
2. Connect the positive and negative poles of the battery with the positive and
negative poles of DC terminal.
CAUTION: Take care not to connect positive and negative leads adversely,
otherwise the generator and the storage battery will be damaged severely. Do
not make positive and negative leads to be touched each other, or the storage
battery will be short circuit.
NOTE: The DC output current should not be more than 7A, when charging the
large capacity battery, the fuse of DC power supply may be burned off and
broken easily for large charging current.
2-7.5 Charging the battery
1. For the electric starter on the generator sets, the 12V battery is automatically
charged through the regulator on the side of the engine when it is running.
2. If the generator is not used for long periods of time, the battery should be
disconnected to avoid energy loss from the battery.
3. Do not connect the negative and positive terminals of the battery together at
any time. Doing so will damage the battery and cause serious injuries.
4. Do not reverse the polarities when attaching the battery cables to the battery.
Doing so will damage both the battery and the electric starter.
5. When charging the battery, the battery produces flammable gases. Do not
smoke, let flames, and sparks get near the battery while it is charging as
this may cause a fire.
To avoid sparking while connecting the cables to the battery, first, connect the
cables to the battery then to the motor. To disconnect battery cables, first
disconnect the motor end of the cable.
2-8 Stopping the generator
1. Take the electrical load off the generator.
2. Put the speed handle in the "RUN" position and let the engine run for 3
minutes after unloading. Do not stop the diesel engine immediately let it
