5. Installation and Wiring
Proper installation is crucial for the safe and accurate operation of the device. Refer to the wiring diagram provided with the product for specific connection points.
Wiring Instructions:
- Power Disconnection: Ensure all power to the circuit is turned off at the main breaker before beginning installation.
- Mounting: Mount the device in a suitable electrical enclosure or panel, ensuring adequate ventilation.
- Main Power Connections: Connect the three live wires (L1, L2, L3) and the neutral wire (N) from the main power supply to the corresponding terminals on the device.
- Load Connections: Connect the load wires to the output terminals of the device.
- Transformer Connection (for Leakage Measurement): The external current transformer (CT) is essential for leakage current measurement. The transformer must pass through a neutral wire and three live wires at the same time. Failure to do so will prevent accurate leakage value measurement. Connect the CT secondary wires to the designated leakage input terminals on the device.
- Verification: Double-check all wiring connections for tightness and correctness before restoring power.
Note: Always follow local electrical codes and regulations. If you are unsure about any part of the installation, consult a qualified electrician.
