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

**2.** Stationary diesel generator sets should be installed indoors on a foundation that complies with regulations and should be elevated 

0.30 to 0.40 meters above the indoor floor. Mobile diesel generator sets must be placed in a horizontal position, securely stabilized, 

with their trailers properly grounded and both front and rear wheels blocked. Diesel generator sets used outdoors should be equipped with protective shelters.  

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

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

**4.** The installation environment for diesel generator sets on 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 lines 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.
