1. Distribution cabinet shall be placed on the foundation section steel one by one according to the layout of construction drawing. The verticality adjustment of the cabinet surface and side of the individual cabinet panel can be solved by adding pad iron, but it can not exceed three pieces, and it can be welded firmly. After each set of the cabinet (panel) is in place, the levelness and deviation of the panel surface shall be adjusted to meet the requirements of the construction specification.

2. The wall mounted distribution box can be fixed on the wall with expansion bolts, but the dovetail bolts shall be embedded in the hollow brick or block wall or fixed with the pull bolts.

3. The distribution box shall be embedded in the installation, and the panel after installation shall be flat with the wall.

4. After the cabinet (panel) adjustment is finished, the cabinet body and foundation section steel shall be fastened with bolts.

5. Cabinet (panel) grounding: each cabinet panel is connected with foundation steel separately. Copper wire can be used to reliably connect PE row in cabinet with grounding bolt, and spring washer must be added to prevent looseness. Each cabinet door shall be reliably connected with PE row with copper braided wire.

6. The top of cabinet (panel) shall be connected with bus bar. It shall be fastened by bus matching wrench as required, and neutral Vaseline shall be applied to the contact surface. When connecting the busbar between cabinets, it is necessary to pay attention to whether the busbar is too close to other devices or shell, and pay attention to the correct phase.

7. Control circuit inspection: check whether the line is loose due to transportation and other factors, fasten them one by one, and whether the electrical components are damaged. In principle, the control line of cabinet (panel) is checked at the factory, and the line in the cabinet shall not be adjusted independently. If any problem is found, contact the supplier.

8. After the control line is calibrated, simmer each core wire into a circle, and connect it to each terminal board with galvanized screws, eyeglasses and spring pads. One terminal on each side of terminal board is pressed with one wire, which cannot exceed two, and eye ring is added between two wires. Multiple strands of wire shall be rinsed and no broken shares are allowed.
