1. Introduction
This manual provides essential information for the safe and efficient installation, operation, and maintenance of your JOYELEC SS766N Single Phase Electronic Energy Meter. Please read this manual thoroughly before using the product and retain it for future reference.
The JOYELEC SS766N is designed to accurately measure the total energy consumption (kWh) of a single-phase AC circuit. It features a clear LCD display and is suitable for DIN rail mounting.
2. Product Overview
2.1 Features
- Total Energy Consumption Display: The LCD screen displays only the total energy consumption (kWh) of the connected circuit. It does not feature a backlight.
- Memory Function: The meter retains the total energy consumption value even after power interruption. It continues recording from the last saved value once power is restored. The total energy consumption value cannot be reset to zero after initial use.
- Accurate Measurement: Utilizes large-scale integrated circuits and SMT technology for precise and reliable electrical energy measurement. This helps in monitoring and recording circuit equipment energy consumption for cost calculation and energy saving.
- Low Power Consumption: The entire unit consumes less than 2W / 5VA. Approximately 1 kWh of power is consumed only after 500 hours of continuous operation, minimizing additional cost.
- Easy Installation: Designed for standard DIN35mm rail mounting, allowing for installation in distribution boxes. It is secured with clips for stable placement.

3. Safety Instructions
WARNING: Electrical shock hazard. Installation and maintenance should only be performed by qualified personnel.
- Always disconnect power to the circuit before installing or servicing the energy meter.
- Ensure all wiring connections are secure and comply with local electrical codes and standards.
- Do not exceed the maximum rated current (60A) or load capacity (13000W) of the device.
- Do not open the meter casing. There are no user-serviceable parts inside.
- Keep the device away from moisture, dust, and extreme temperatures.
4. Setup and Installation
4.1 Mounting
The SS766N energy meter is designed for mounting on a standard 35mm DIN rail. Locate a suitable position within your distribution box or electrical panel.
- Ensure the DIN rail is securely installed.
- Align the meter's mounting clip with the DIN rail.
- Press the meter firmly onto the rail until the clip engages and locks the meter in place.


4.2 Wiring Diagram
Follow the wiring diagram carefully. Incorrect wiring can damage the device or pose a safety risk. The meter requires connection to both the live (L) and neutral (N) wires of the power supply and the circuit to be monitored.
- Identify the Live (L) and Neutral (N) terminals on the energy meter. These are typically labeled.
- Connect the incoming Live (L) wire from the power source (e.g., circuit breaker) to the Live input terminal of the meter.
- Connect the incoming Neutral (N) wire from the power source to the Neutral input terminal of the meter.
- Connect the Live (L) output terminal of the meter to the Live wire of the electrical equipment/circuit you wish to monitor.
- Connect the Neutral (N) output terminal of the meter to the Neutral wire of the electrical equipment/circuit you wish to monitor.
- Ensure all connections are tight and secure.


5. Operating Instructions
5.1 Powering On
After successful installation and wiring, restore power to the circuit. The meter's LCD display will illuminate and begin showing the total accumulated energy consumption in kWh.
5.2 Reading the Display
The SS766N meter is designed to display only the total energy consumption in kilowatt-hours (kWh). There are no other parameters or modes to cycle through.

Important Note on Memory Function: The meter's total energy consumption value cannot be reset to zero after it has started recording. This feature ensures continuous and cumulative tracking of energy usage.

6. Maintenance
6.1 Cleaning
To clean the meter, ensure power is disconnected. Use a soft, dry cloth to wipe the exterior. Do not use abrasive cleaners, solvents, or spray liquids directly onto the device.
6.2 Storage
If storing the device, keep it in a cool, dry place, away from direct sunlight and extreme temperatures. Ensure it is protected from physical damage.
7. Troubleshooting
7.1 Common Issues and Solutions
- No Display:
- Check if power is supplied to the circuit and the meter.
- Verify all wiring connections are secure and correct according to the diagram.
- Ensure the circuit breaker is in the ON position.
- Incorrect Readings / No Energy Accumulation:
- Double-check the wiring connections for Live (L) and Neutral (N) inputs and outputs.
- Ensure the load connected to the meter is within its specified operating range (max 13000W).
- Confirm the meter is correctly installed on the DIN rail and not loose.
- Meter is Hot:
- This may indicate an overload. Immediately disconnect power and check the connected load. Ensure it does not exceed 13000W.
- If the issue persists after reducing the load, contact a qualified electrician.
If you encounter issues not listed here or if troubleshooting steps do not resolve the problem, please consult a qualified electrician or contact customer support.
