1. Te faanahoraa i roto ia ' na iho: Electrical components and wiring within the box must be neatly organized, Te mau nota, and aesthetically arranged for ease of maintenance. E ti'a i te rotoraa ia vai ti'amâ noa i te repo e te mau hu'ahu'a. E tia i te mau niuniu atoa ia vai maitai noa ma te ore e ino.
2. Wire Specifications: The cross-sectional area of the wires should meet standard requirements, capable of handling the normal working current with some margin.
3. Wire Protection: Wires should not be exposed to the air directly. Ei hi'oraa, when connecting an Te mau mana'o tauturu no te tuatapaparaa e te haapiiraa to an audio-visual alarm line, an explosion-proof flexible conduit must be used.
4. Cable Sealing: Inlet and outlet cables must pass through rubber sealing rings, tightened with washers and compression nuts to ensure the integrity of the explosion-proof enclosure’s seal. Cables should not be loose.
5. Component Placement in Te faaheporaa maitai Cabinets: Internal electrical components, such as frequency converters, should be placed close to the air inlet and away from the air outlet.
6. Grounding of Metal Cabinets: Metal explosion-proof distribution boxes must be reliably grounded, with the Te mau nota wire connected to the cabinet’s outer shell. For three-phase systems without a neutral wire, the grounding wire should have a cross-sectional area of at least 4mm². In a three-phase three-wire system, the ground cross-section should also be at least 4mm².
7. Wiring Adherence: Wiring must strictly follow the schematic diagrams. Wires should be properly labeled to ensure secure connections at terminals.
