This image illustrates the different electrical parameters that can be shown on the LCD, including KWh for positive and reverse consumption, total power, instantaneous power, power factor, frequency, voltage, and current. Some models may feature RS485 communication.
Configuração e instalação
The DDS661 energy meter is designed for easy installation on a standard 35mm DIN rail. Ensure the installation location is dry, well-ventilated, and free from excessive vibration or electromagnetic interference.
Etapas de instalação:
- Desconexão de energia: Before beginning any installation, ensure that the main power supply to the circuit where the meter will be installed is completely disconnected and locked out.
- Montagem: Attach the meter securely to a 35mm DIN rail. The meter features a clip mechanism for quick mounting.
- Fiação: Connect the input and output wires according to the wiring diagram provided on the meter's casing or in the detailed wiring instructions (not provided in this general manual). Ensure correct phase and neutral connections. The meter supports up to 60A.
- Verificação: Verifique novamente todas as conexões quanto ao aperto e à exatidão.
- Restauração de energia: Restore power to the circuit. The meter's LCD display should illuminate, indicating proper function.

Instruções de operação
Display Readings:
The DDS661 meter features an LCD backlight display that cycles through various parameters or can be manually advanced depending on the model. Common display parameters include:
- kWh: Consumo total de energia ativa.
- Volumetage (v): Instantaneous line voltage.
- Atual (A): Instantaneous line current.
- Potência (W): Instantaneous active power.
- Fator de potência (FP): The ratio of real power to apparent power.
- Frequência (Hz): The frequency of the AC supply.
The green LED indicator flashes at a rate of 1000 imp/kWh, indicating active energy measurement. A faster flash rate signifies higher power consumption.
RS485 Communication (for DDS661-RS485 models):
For models equipped with RS485, the meter can be integrated into a monitoring system for remote data acquisition. Refer to the specific RS485 communication protocol documentation for details on data registers, baud rates, and addressing. This functionality allows for convenient management and monitoring of power status.
Manutenção
The NENEN DDS661 energy meter is designed for long-term, maintenance-free operation under normal conditions. Regular checks are recommended:
- Limpeza: Mantenha o medidor limpo e livre de poeira. Use um pano macio e seco para a limpeza. Não utilize produtos de limpeza abrasivos ou solventes.
- Verificações de conexão: Periodically inspect wiring connections to ensure they remain tight and free from corrosion.
- Condições ambientais: Assegurar que o ambiente operacional permaneça dentro das faixas de temperatura e umidade especificadas.
Solução de problemas
| Problema | Possível causa | Solução |
|---|---|---|
| O visor do medidor está em branco. | Sem alimentação elétrica; fiação incorreta; defeito interno. | Check power supply to the circuit. Verify wiring connections. If power is present and wiring is correct, the meter may be faulty and require replacement. |
| KWh reading not increasing. | No load connected; incorrect wiring; internal fault. | Ensure a load is connected and drawing power. Verify wiring, especially input/output terminals. If issues persist, the meter may be faulty. |
| Green LED not flashing. | No power consumption; LED fault. | Confirm that there is active power consumption. If power is being consumed and the LED does not flash, there might be an internal issue. |
| Leituras imprecisas. | Incorrect wiring; external interference; meter calibration issue. | Re-check all wiring connections. Ensure the meter is not exposed to strong electromagnetic fields. If suspected calibration issues, contact support. |
For problems not listed here or if solutions do not resolve the issue, please contact NENEN customer support.
