1. Introduction
This manual provides detailed instructions for the installation, operation, and maintenance of the SOBOUR DDSU666 and DTSU666 series single-phase DIN rail energy meters. These meters are designed for accurate measurement of active energy consumption in various electrical systems. Please read this manual thoroughly before installation and operation to ensure safe and correct usage.
2. Safety Information
Warning: Installation and maintenance should only be performed by qualified personnel. Failure to follow these instructions may result in electric shock, fire, or damage to the device.
- Always disconnect power before installing or servicing the meter.
- Ensure proper grounding to prevent electrical hazards.
- Do not operate the meter in environments exceeding its specified operating conditions.
- Avoid exposing the meter to direct sunlight, high temperatures, or excessive humidity.
- Do not open the meter casing; there are no user-serviceable parts inside.
3. Product Overview
The SOBOUR DDSU666 and DTSU666 are compact, single-phase electronic energy meters designed for DIN rail mounting. They feature an LCD display for clear readings of energy consumption and may include RS485 communication capabilities for remote monitoring.
This image displays two SOBOUR DDSU666 single-phase electronic energy meters designed for DIN rail mounting. Both meters feature an LCD screen for displaying energy consumption data. The left meter shows specifications including 220V 5(60)A, 800imp/kWh, and compliance with GB/T 17215.321-2008. The right meter indicates 220/230V 5(80)A 50/60Hz, C1.1, 800imp/kWh, and a CE mark, along with an RS485 symbol, suggesting communication capabilities.
4. Setup and Installation
4.1. Mounting
The meter is designed for standard 35mm DIN rail mounting. Ensure the mounting location is stable, free from vibrations, and provides adequate ventilation.
- Locate an appropriate section of the DIN rail within your electrical panel.
- Align the meter's DIN rail clip with the rail.
- Press the meter firmly onto the rail until it clicks into place.
4.2. Wiring
Important: All wiring must be performed with the main power supply disconnected. Refer to local electrical codes and standards.
- Connect the incoming live (L) and neutral (N) wires to the designated input terminals.
- Connect the outgoing live (L) and neutral (N) wires to the designated output terminals.
- For models with RS485 communication, connect the A and B data lines to the corresponding terminals of your communication network.
- Ensure all connections are secure and properly insulated.
5. Operating Instructions
5.1. Power On
After successful installation and wiring, restore power to the circuit. The meter's LCD display should illuminate and begin showing readings.
5.2. LCD Display
The LCD display typically shows the total active energy consumption in kilowatt-hours (kWh). Some models may cycle through various parameters such as instantaneous voltage, current, power, and frequency. Consult the specific model's detailed documentation for display navigation if buttons are present.
5.3. Pulse Output
The meter provides a pulse output (800imp/kWh) for external devices to count energy consumption. Each pulse represents a specific amount of energy consumed, as indicated by the meter's specifications.
5.4. RS485 Communication (if applicable)
For models equipped with RS485, the meter can be integrated into a monitoring system. Communication parameters (e.g., baud rate, parity, address) may need to be configured. Refer to the RS485 communication protocol guide for detailed setup and data retrieval instructions.
6. Maintenance
The SOBOUR energy meter is designed for long-term, maintenance-free operation. However, periodic checks are recommended:
- Cleaning: Use a soft, dry cloth to clean the meter's exterior. Do not use abrasive cleaners or solvents.
- Connection Check: Periodically inspect wiring connections to ensure they remain tight and free from corrosion.
- Environmental Check: Ensure the operating environment remains within specified temperature and humidity ranges.
7. Troubleshooting
If you encounter issues with your energy meter, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Display is blank | No power supply; faulty wiring | Check power connections and circuit breaker. Ensure wiring is correct. |
| Meter not counting energy | Incorrect wiring; no load connected | Verify wiring according to the diagram. Ensure there is an active load drawing power. |
| Inaccurate readings | Incorrect current transformer (CT) ratio (if applicable); external interference | Ensure correct CT ratio settings. Check for strong electromagnetic interference. |
| RS485 communication failure | Incorrect wiring; wrong communication parameters; device address conflict | Check RS485 A/B wiring. Verify baud rate, parity, and stop bits. Ensure unique device addresses. |
If the problem persists after attempting these solutions, contact customer support.
