1. Introduction
The EARU Electric Single Phase Energy Meter (Model EARU-1006) is designed for accurate monitoring of electrical parameters in single-phase 220V, 80A systems. It provides real-time data for voltage (V), current (A), power (W), power factor (PF), frequency (Hz), and kilowatt-hour (kWh) consumption. This device assists in understanding energy usage and identifying potential inefficiencies in your electrical system.
2. Safety Information
- Installation must be performed by a qualified electrician in accordance with local electrical codes and regulations.
- Ensure the main power supply is disconnected before installation or maintenance to prevent electric shock.
- Do not operate the device if it appears damaged.
- This device is designed for indoor use in a dry environment. Avoid exposure to moisture or extreme temperatures.
- The maximum current rating is 80A. Do not exceed this limit.

6. Setup and Installation
Important: Ensure all power is disconnected before proceeding with installation.
- Mounting: The EARU-1006 is designed for 35mm DIN rail mounting. Snap the meter onto the DIN rail securely within your electrical panel.
- Wiring: Refer to the wiring diagram below for correct connection. This is a single-phase, 2-wire direct connection meter.
- Connect the Live (L) input wire to the designated 'L In' terminal.
- Connect the Neutral (N) input wire to the designated 'N In' terminal.
- Connect the Live (L) output wire to the designated 'L Out' terminal.
- Connect the Neutral (N) output wire to the designated 'N Out' terminal.
- Power On: Once all connections are secure and verified, restore power to the circuit. The LCD display should illuminate and begin showing readings.

7. Operating Instructions
The energy meter operates automatically once powered on. The LCD display continuously cycles through or shows multiple parameters simultaneously.
- Reading Parameters: The display shows Voltage (V), Current (A), Power (W), Power Factor (PF), Frequency (Hz), and Kilowatt-hour (kWh).
- kWh Reading: The meter records total kWh consumption. This reading is permanent and accumulates over time.
- kWh Reset: The meter features a manual reset function for the kWh reading. Consult the device's physical buttons or specific instructions on the meter itself for the reset procedure. Typically, a long press on a designated button (if present) will reset the temporary kWh value. The total kWh value is usually non-resettable.
8. Maintenance
- Cleaning: Use a soft, dry cloth to clean the meter's exterior. Do not use abrasive cleaners or solvents.
- Inspection: Periodically inspect the wiring connections to ensure they are tight and free from corrosion.
- Environment: Ensure the operating environment remains within the specified temperature and humidity ranges.
9. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Display is blank | No power supply; Incorrect wiring | Check power connections and ensure power is supplied. Verify wiring against the diagram. |
| Incorrect readings | Incorrect wiring; Faulty connection | Double-check all wiring connections. Ensure wires are securely fastened. |
| kWh not accumulating | No load connected; Meter malfunction | Ensure there is an active electrical load connected through the meter. If problem persists, contact support. |
