-Mechanical installation: Installed on a rigid mounting bracket using bolt fixing method, the bracket needs to have sufficient load-bearing capacity (module weight is about 15kg), and the installation plane flatness error should be ≤ 0.1mm/m to avoid uneven force on the module causing damage to the internal structure; The spacing between modules should be ≥ 20cm to prevent mutual interference during operation.

-Electrical installation: Before connecting the power copper bars, the surface oxide layer should be removed, conductive paste should be applied, and bolts should be tightened with a torque wrench according to the specified torque (recommended 50N · m) to ensure good contact; The drive circuit should use shielded twisted pair cables, with the shielding layer grounded at one end, and be wired separately from the power circuit with a spacing of ≥ 30cm to avoid electromagnetic interference; Before connecting the water-cooled pipeline, it is necessary to flush the pipeline to remove impurities, and conduct a pressure test after connection to ensure no leakage.

-Safety protection: High voltage warning signs should be set up in the module installation area, and installation personnel should wear insulated protective equipment (insulated gloves, insulated shoes, etc.); Before installation, it is necessary to ensure that the system is powered off and the capacitors are discharged to avoid the risk of high voltage electric shock.

2. Debugging process
