6. Setup and Installation
Follow these steps for proper installation of the D52-2066 meter. Ensure all power is OFF before proceeding.
6.1 Din-Rail Mounting
The D52-2066 is designed for standard Din-Rail installation. Securely mount the meter onto a compatible Din-Rail within your electrical panel.
6.2 Wiring Instructions
The wiring method depends on whether your meter uses a built-in Current Transformer (CT) or an external CT, and the current level.
Method 1: Wiring with Built-in CT (AC Current lower than 100A)
- Identify the measuring signal input terminals (typically labeled 1 and 2) and the load terminals.
- Connect the main circuit wire (measuring signal) through the hole in the built-in current transformer located on the right side of the meter. Ensure the wire passes correctly through the CT.
- Connect the voltage input wires to terminals 1 and 2 of the meter.
- Connect the load to the output side of the circuit.
Image: Wiring diagram for the D52-2066 meter when using its built-in current transformer for AC currents below 100A. The measuring signal wire passes through the CT hole on the meter's right side, and voltage inputs connect to terminals 1 and 2.
Method 2: Wiring with External CT (for higher currents or specific installations)
- Identify the secondary current transformer terminals (typically blue terminals) on the meter.
- Connect the green wire of the external secondary current transformer to the blue terminal of the meter.
- Make the wire of the measurement circuit pass through the hole in the external current transformer.
- Connect the voltage input wires to the appropriate terminals (e.g., 3 and 4) on the meter.

7. Operation
Once properly installed and powered on, the meter will automatically begin measuring and displaying the electrical parameters.
7.1 Display Readings
The multi-function digital display will show the following parameters:
- Active Power (W)
- Electric Energy (KWH)
- AC Voltage (V)
- Frequency (Hz)
- AC Current (A)
- Power Factor (PF)

7.2 Resetting Electric Energy (KWH)
To reset the accumulated electric energy (KWH) reading:
- Locate the "RESET" button on the front panel of the meter.
- Press and hold the "RESET" button for approximately 5 seconds.
- The electric energy (KWH) value will reset to zero.
8. Maintenance
- Keep the meter clean and free from dust. Use a soft, dry cloth for cleaning.
- Avoid exposing the meter to excessive moisture, direct sunlight, or extreme temperatures.
- Do not attempt to open or repair the meter yourself. Refer to qualified service personnel for any issues.
9. Troubleshooting
- No Display / Meter Not Powering On:
- Check the power supply to the meter's voltage input terminals.
- Ensure all wiring connections are secure and correct according to the diagrams.
- Verify that the input voltage is within the specified range (AC 40-300V or AC 250-450V).
- Incorrect Readings:
- Confirm that the current transformer (CT) is correctly installed and the measurement circuit wire passes through it properly.
- Ensure the meter is used with a 50Hz AC city electricity supply. Using it with square wave, inverter output, or corrected sine wave will result in incorrect readings or damage.
- Check for loose connections in the wiring.
- KWH Not Resetting:
- Ensure you are pressing and holding the "RESET" button for the required duration (approximately 5 seconds).
