1. The grounding wire connection point is typically at the bottom end of the diesel generator set. When installing the grounding wire, it must be connected to a suitable grounding point.

2. The connection of the neutral grounding wire in alternators is typically determined during installation by the user. When a diesel generator set is used as a power source, the neutral wire must be directly connected to the factory's grounding wire.

3. For more complex installations, choose the grounding midpoint to ensure the correct operation of the diesel generator set or to protect equipment, such as detecting grounding faults and reducing grounding circulating current to small generator rentals.

4. The grounding wire must be arranged according to the recommendations of the user and local authorities.

5. Ensure that the equipment wiring is consistently maintained effectively. The maintenance of the wiring system should be strictly carried out according to the instructions.
