(Customer – Requested)<\/p>\n\n\n\n

Here We Explain in Detail the Differences between the Two, the Specific Meaning of the Customer’s Wiring Method and the Reasons Behind It:<\/p>\n\n\n\n

I. Our Standard 3 – Wire Wiring Method of Photocell (ANSI Standard)<\/h2>\n\n\n\n

The ANSI – standard wiring method commonly used for our Long – Join photocell products consists of 3 wires:<\/p>\n\n\n\n

Schwarz<\/td>Power Input (Line)<\/td>Connect to the live wire of the power supply<\/td><\/tr>

\"\"<\/figure>\n\n\n\n
\"\"<\/figure>\n\n\n\n

In this standard wiring method, the input and output share one neutral wire (the white Neutral wire).<\/p>\n\n\n\n

II. Customer – Requested – Wire Wiring Method (Black for Li, White for N; Red for Lo, White for N)<\/h2>\n\n\n\n

The customer’s wiring method uses 4 wires and is a “completely separated input – output” wiring method:<\/p>\n\n\n\n

Drahtfarbe<\/th>Function Description<\/th>Wiring Terminal<\/th><\/tr><\/thead>
Schwarz<\/td>Input Live Wire (Line In)<\/td>Connect to the live wire input of the AC power supply (Li)<\/td><\/tr>
Wei\u00df<\/td>Input Neutral Wire (Neutral In)<\/td>Connect to the neutral wire input of the AC power supply (Ni)<\/td><\/tr>
Rot<\/td>Output Live Wire (Line Out)<\/td>Output to the live wire of the load (Lo)<\/td><\/tr>
Wei\u00df<\/td>Output Neutral Wire (Neutral Out)<\/td>Output to the neutral wire of the load (No)<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

This method is called “complete input – output isolation”, meaning that the live and neutral wires of the input and output ends are completely independent and not shared.<\/p>\n\n\n\n

III. Specific Differences<\/h2>\n\n\n\n
Specific Difference Points<\/th>Our Commonly Used 3 – Wire Method<\/th>Customer’s 4 – Wire Isolation Method<\/th><\/tr><\/thead>

IV. Reasons Why Customers Adopt the 4 – Wire Method of photocell<\/h2>\n\n\n\n

Customers specifically request the 4 – wire (2 inputs + 2 outputs) wiring method usually for the following reasons:<\/p>\n\n\n\n

1. Higher Safety Requirements:<\/h3>\n\n\n\n
    \n
  • Regulations in some countries or regions where customers are located require that the input and output circuits must be completely isolated.<\/li>\n\n\n\n
  • Isolating the input and output circuits can avoid equipment damage or electric shock risks caused by neutral wire breakage or misconnection.<\/li>\n<\/ul>\n\n\n\n

    2. Higher Reliability and Equipment Protection:<\/h3>\n\n\n\n
      \n
    • The completely separated input – output wiring method is conducive to providing better electrical protection.<\/li>\n\n\n\n
    • In case of a fault, it is easier to detect and determine the problem, and clarify the responsibility.<\/li>\n<\/ul>\n\n\n\n

      3. Specific Certification Requirements:<\/h3>\n\n\n\n
        \n
      • Customers may specifically require the use of this input – output isolation scheme when applying for certain high – level safety certifications (such as specific UL certification standards in North America or government\/municipal streetlight project specifications) to meet specific certification requirements.<\/li>\n<\/ul>\n\n\n\n

        4. Avoiding Problems Caused by Sharing the Neutral Wire:<\/h3>\n\n\n\n
          \n
        • For example, in large – scale public lighting systems, unbalanced neutral wire loads or voltage differences may pose potential safety hazards, and the isolated wiring method can effectively avoid such problems.<\/li>\n<\/ul>\n\n\n\n

          V. Why Our Products Currently Use 3 – Wires <\/h2>\n\n\n\n
            \n
          • Standardization Considerations<\/strong>: Wiring methods with 3 wires are commonly accepted by standards such as ANSI C136.10\/UL773 and have been widely used. The wiring is simple and easy to understand.<\/li>\n\n\n\n
          • Kosten\u00fcberlegungen<\/strong>: The product structure with 3 – wire wiring is simple. Only a single – pole single – throw relay is needed inside, which results in a low cost and makes the product more competitive in the market.<\/li>\n\n\n\n
          • Wide Application Range<\/strong>: The vast majority of markets and customer projects do not strictly require complete isolation. 3 – wire products are sufficient to meet the needs of most application scenarios.<\/li>\n<\/ul>\n\n\n\n

            However, with the changes in market demands and regulations, for high – end projects or special customer needs, we may consider launching 4 – wire completely isolated products in the future to cover more market demands.<\/p>\n\n\n\n

            VI. Product Realization Methods (if Customers Must Have 4 – Wires)<\/h2>\n\n\n\n

            If customers insist on this wiring method, the factory needs to make corresponding adjustments:<\/p>\n\n\n\n

              \n
            • Relay Configuration Adjustment<\/strong>: A double – pole double – throw relay (DPST Relay) must be used to cut off or connect the live wire and the neutral wire simultaneously.<\/li>\n\n\n\n
            • Internal Circuit Adjustment<\/strong>: The live and neutral wires of the input end enter the input terminals of the relay completely independently, and the output end is then separately output by the relay.<\/li>\n\n\n\n
            • Wiring Terminal Adjustment<\/strong>: Provide independent input and output wiring terminals or wires inside the product.<\/li>\n<\/ul>\n\n\n\n

              VII. Suggestions for Communicating with Customers<\/h2>\n\n\n\n
                \n
              • First, understand the real reasons why customers insist on the 4 – wire method, and confirm whether it is due to regulatory requirements, project requirements, or customer habits.<\/li>\n\n\n\n
              • Clearly inform customers that the 4 – wire solution will increase costs compared to the 3 – wire solution, and the price may rise accordingly.<\/li>\n\n\n\n
              • If customers confirm that they must have 4 – wires, product adjustment and design can be arranged according to the project volume and long – term cooperation prospects.<\/li>\n<\/ul>\n\n\n\n

                VIII. Summary (for Sales to Communicate with Customers)<\/h2>\n\n\n\n

                The core of the customer’s request for the 4 – wire (2 AC inputs, 2 AC outputs) method is to achieve complete isolation of the input and output circuits, so as to improve the safety and reliability of the product. Our current standard ANSI products use the 3 – wire method, which is a conventional wiring method with the input and output sharing the neutral wire and has been widely used in the market.<\/p>\n\n\n\n

                It is recommended to clearly communicate with customers about their specific needs and regulatory requirements to determine whether special customization is required or whether to use our existing standardized and mature products.<\/p>\n\n\n\n

                The above is a detailed description of the differences between the 4 – wire method and the 3 – wire method and the reasons behind them. If you have any other questions or need further technical support, please feel free to ask.<\/p>\n\n\n\n
