4. Setup and Installation
The SDM630MCT ETL power meter is designed for DIN rail mounting. Follow the wiring diagrams carefully to ensure correct and safe installation.
This image displays detailed wiring diagrams for 3-phase 4-wire, 3-phase 3-wire, and 1-phase 2-wire configurations, along with auxiliary power supply and RS485 connections. It also includes a dimensional drawing of the power meter with measurements: 65mm height, 72mm width, and 94.5mm depth.
Installation Steps:
- Mount the power meter onto a standard 35mm DIN rail.
- Ensure all power is disconnected from the circuit where the meter will be installed.
- Connect the voltage inputs (L1, L2, L3, N) according to the appropriate wiring diagram for your system (3-phase 4-wire, 3-phase 3-wire, or 1-phase 2-wire).
- Connect the Current Transformers (CTs) to the corresponding current inputs (I1, I2, I3). Ensure the CTs are correctly oriented (P1/K to source, P2/L to load).
- If using, connect the RS485 communication wires (A, B) and auxiliary power supply as shown in the diagram.
- Double-check all connections for tightness and correctness before restoring power.
5. Operating Instructions
Once installed and powered, the SDM630MCT ETL will display various electrical parameters on its digital screen. Use the front panel buttons to navigate through the display modes and access different measurements.
Display Navigation:
- The display typically cycles through primary measurements like total energy (kWh), voltage, current, and power.
- Refer to the button labels (e.g., U/L, M, P, E) on the device for specific functions such as cycling through phases, accessing menu options, or resetting certain values.
- Detailed parameter settings and advanced functions are typically accessed via the RS485 Modbus interface using compatible software.
