5.1 DIN темир жолду орнотуу
The DDS529MR energy meter is designed for standard 35mm DIN rail installation. Simply clip the meter onto the DIN rail in your electrical panel.
5.2 Электр зымдары боюнча нускамалар
WARNING: Ensure all power is OFF before proceeding with wiring. Incorrect wiring can cause damage to the meter, property, or personal injury.
The meter uses a 2-wire single-phase connection. Refer to the wiring diagram below for proper connections.
- Кубат киргизүү: Connect the Live (L) wire to terminal 1 and the Neutral (N) wire to terminal 4.
- Чыгуу кубаттуулугу: Connect the Live (L) wire to terminal 2 and the Neutral (N) wire to terminal 3.
- RS485 байланыш: Connect RS485 A to terminal A and RS485 B to terminal B. (Refer to the side view image for terminal locations).
- Импульс чыгаруу: Connect the pulse output (SO+, SO-) to terminals 21 and 20 respectively for external pulse counting.
After wiring, ensure all terminal screws are tightened securely. Close the terminal cover before restoring power.

6.1 Display Functions (DDS529MR)
The DDS529MR model features a multifunctional LCD display that cycles through various electrical parameters. Use the 'TURN' button to manually cycle through the display modes. The 'SET' button is typically used for configuration, though specific advanced settings may require the RS485 interface.
Дисплейде адатта төмөнкүлөр көрсөтүлөт:
- кВт.саат: Total accumulated active energy consumption.
- V: Instantanous voltage.
- A: Instantaneous current.
- W: Instantaneous active power.
- PF: Күч фактору.
- Гц: Жыштык.
The DDS529R model will only display kWh.
6.2 Pulse LED Indicator
A pulse LED on the front panel indicates the working status of the meter. It flashes at a rate of 1000 impulses per kWh, providing a visual confirmation of energy consumption.

7. Техникалык тейлөө
- Keep the meter clean and free from dust. Use a soft, dry cloth for cleaning. Do not use liquid cleaners.
- Regularly check all wiring connections to ensure they remain secure.
- Ensure the operating environment stays within the specified temperature and humidity ranges.
8. Кыйынчылыктарды
8.1 No Display / Meter Not Powering On
- Check the main power supply to ensure it is active.
- Verify that the Live (L) and Neutral (N) wires are correctly connected to terminals 1 and 4 respectively, and that connections are secure.
- Бааланган томду камсыз кылууtage (230V AC) is supplied to the meter.
8.2 Incorrect Readings
- Confirm that the wiring for input and output is correct as per the diagram (Figure 3).
- Ensure the load connected is within the meter's maximum current rating (80A).
8.3 RS485 Communication Issues
- Check the RS485 A and B connections for correct polarity and secure contact.
