1. The grounding wire connection point is generally at the end of the chassis of the diesel generator set. When installing the grounding wire, it must be connected to the appropriate grounding wire position.

2. The connection of the grounding neutral line of the alternator is usually determined by the user during installation. When the diesel generator set is the only power supply, the neutral line must be directly connected to the factory grounding wire.

3. For more complex installation, the grounding midpoint shall be selected to ensure the correct operation of diesel generator set or protect equipment, such as finding grounding fault and minimizing grounding circulating current.

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

5. Ensure that the equipment wiring is maintained effectively all the time, and the maintenance of the wiring system shall be carried out in strict accordance with the instructions.

In order to achieve accurate wiring of diesel generator set, first distinguish whether the terminal or outgoing line is phase line or zero line. Usually, each terminal or outgoing line of the generator is marked with a certain mark to distinguish whether it is phase line or zero line. As long as attention is paid to it, it can be distinguished. The zero line terminal is often marked with the letter M or O, or marked with a grounding symbol next to the wiring.

If there is no symbol on the zero line terminal or the symbol is unclear, it can be tested and identified with a voltmeter during the operation of the generator. Do not use the operation of "touching fire".
