Eastron SDM630 Modbus V2 MID Single/Three-Phase Energy Meter Instruction Manual

1. Pengenalan

This manual provides essential information for the safe and efficient installation, operation, and maintenance of the Eastron SDM630 Modbus V2 MID Single/Three-Phase Energy Meter. The SDM630 series is a 100A multifunction three-phase electricity meter designed for direct connection and DIN rail mounting. It is capable of measuring and displaying characteristics of 1-phase 2-wire (1p2w), 3-phase 3-wire (3p3w), and 3-phase 4-wire (3p4w) power supplies. It features an intuitive navigation menu and a high-visibility LCD display. The meter is self-powered, eliminating the need for an external auxiliary power supply.

4.1 Pemasangan

The SDM630 Modbus V2 is designed for DIN rail mounting. Ensure the DIN rail is securely fastened within an appropriate enclosure. The meter occupies 4 DIN modules.

4.2 Pendawaian

The meter requires direct mains voltage inputs for operation. Connect the live in, live out, neutral in, and neutral out wires to the designated terminals. Refer to the wiring diagram provided on the meter's casing or in the full technical datasheet for correct phase and neutral connections for 1p2w, 3p3w, or 3p4w systems. Ensure all connections are tight and properly insulated.

5. Arahan Operasi

The SDM630 features an intuitive navigation menu accessible via the front panel buttons.

• Butang 'M': Typically used to enter the menu or cycle through main display screens.
• 'P' Button: Used to scroll through parameters within a menu or display screen.
• 'E' Button: Used to confirm selections or exit a menu.

Upon power-up, the meter will display default parameters such as total energy (kWh). Use the navigation buttons to view various electrical parameters including voltage, current, active power, reactive power, apparent power, power factor, and frequency for each phase and total.

6. Penyelenggaraan

The Eastron SDM630 Modbus V2 is designed for minimal maintenance. Follow these guidelines to ensure optimal performance:

• Keep the meter clean and free from dust. Use a soft, dry cloth for cleaning. Do not use liquid cleaners.
• Periksa sambungan pendawaian secara berkala untuk kesesakan dan tanda-tanda haus atau kakisan.
• Pastikan persekitaran operasi kekal dalam julat suhu dan kelembapan yang ditetapkan.

7. Penyelesaian masalah

If you encounter issues with your SDM630 meter, consider the following common troubleshooting steps:

• Tiada Paparan: Check the main power supply to the meter. Ensure all voltage inputs (Live In/Out, Neutral In/Out) are correctly connected and energized.
• Bacaan yang salah: Verify that the wiring connections match the system type (1p2w, 3p3w, or 3p4w) and that phase sequence is correct for three-phase systems. Ensure the meter's internal settings (if configurable) match the installation.
• Modbus Communication Failure: Check Modbus wiring (RS485 A/B lines), termination resistors, and ensure the Modbus address and baud rate settings on the meter match the master device.
• Meter Not Responding: Try cycling the power to the meter. If the issue persists, contact technical support.
