**1.** The rated voltage of the diesel generator at the construction site must match the voltage level of the external power supply line.

**2.** Stationary diesel generator sets should be installed indoors on a foundation that meets the specified requirements, raised 30–40 cm 

above the indoor floor. Mobile diesel generator sets must be placed in a level position, securely stabilized, with their trailers reliably 

grounded and blocked at both the front and rear. Diesel generator sets used outdoors should be equipped with protective shelters.

**3.** The arrangement of diesel generator sets and their control, distribution, and maintenance rooms must ensure electrical safety distances 

and meet fire safety requirements. Exhaust pipes must extend outdoors, and storage of fuel drums is strictly prohibited indoors or near exhaust pipes.

**4.** The installation environment for diesel generator sets at the construction site should be selected close to the load center, 

with convenient access for incoming and outgoing cables, unobstructed surrounding roads, and avoiding locations downwind of 

pollution sources or prone to water accumulation.

**5.** The power supply of the generator set must be interlocked with the external power line supply, and parallel operation 

with the external power line is strictly prohibited. When two or more generator sets are operated in parallel, a synchronization 

device must be installed, and power should only be supplied to the load after the units are synchronized.

**6.** The environment should be tidy and free of water accumulation, with indoor ventilation maintained and proper arrangements made 

for smoke and exhaust emissions.
