Frequently Asked Questions (FAQ)

  • Q: Can I use 990NAD21930 with non-Schneider equipment having a SUB-D 9 port?
    A: Although we designed this cable for Schneider Modicon series, the SUB-D 9 connector follows standard pinout. When electrical parameters match, it may work with other devices. We recommend using it with Modicon Momentum or Altivar 71/61 for guaranteed performance.
  • Q: What is the wire color code for the flying leads?
    A: Please refer to the included instruction sheet or the official 990NAD21930 datasheet. Typically, the leads include Modbus Plus signals like D0, D1, and common reference.
  • Q: Is this cable suitable for outdoor installation?
    A: 990NAD21930 is rated for indoor use only (0 to 40°C). For outdoor applications, place it inside a weatherproof enclosure away from direct sunlight and moisture.
  • Q: Does the package include terminal blocks or connectors for the flying leads?
    A: No, the package contains only the cable with tinned bare wire ends. You must connect these wires directly to your junction box terminal strips.
  • Q: What about stock status and shipping methods?
    A: We keep brand new original 990NAD21930 cables in stock. We ship orders within 5 days via FedEx, UPS, or DHL.
  • Q: Can I return this item?
    A: Yes, we accept returns within 30 days. The product must remain unused, in its original packaging, and in re-sellable condition.
