Energy meter connection diagram
The MEW-02 ETH should be connected to the electrical installation in accordance with the diagram included in the operating instructions.
- Voltage supply terminals: connect the phase wires to terminals V1, V2, V3 and the neutral wire to terminal N
- Current transformers:
- Each SC-16 transformer should be connected according to the terminal markings. The red wire should be screwed to the S1 input, and the black wire to the S2 input of the appropriate channel (I1, I2, I3)
- The arrow on the transformer must point in the direction of current flow in the primary conductor.
- Power: After the power cables and transformers are properly connected, turn on the power to the device, making sure that the LEDs indicate the correct operation of each phase
Please ensure that all connections are made according to the manufacturer's instructions to avoid measurement errors and ensure installation safety.
