3. സജ്ജീകരണവും ഇൻസ്റ്റാളേഷനും
The EASTRON SDM630MCT V2 is designed for DIN rail mounting within an electrical enclosure. Proper installation requires knowledge of electrical systems and adherence to local electrical codes. It is strongly recommended that installation be performed by a qualified electrician.
3.1 Current Transformer (CT) Connection
This meter requires external Current Transformers (CTs) for operation. CTs are essential for measuring current in high-amperage circuits and provide isolation between the measurement device and the main power lines. The meter supports 1A or 5A CT inputs. Ensure the CTs are correctly sized for your application and connected according to the wiring diagram provided in the full product manual.
CT-powered meters are widely used to monitor power grid operation. Multiple CTs may be installed for different applications, such as protective devices and revenue measurement, to ensure proper isolation and allow for CTs with varying characteristics (accuracy, overload capacity).
3.2 Modbus RS485 Connection
The Modbus RS485 interface allows the meter to communicate with other devices, such as data loggers, PLCs, or building management systems. Connect the RS485 A and B terminals to your Modbus network. Ensure proper polarity and termination resistors are used as per Modbus standards. The meter's Modbus address can typically be configured via the device's menu.
3.3 ഫിസിക്കൽ ഇൻസ്റ്റലേഷൻ
- Mount the meter securely on a standard 35mm DIN rail within an appropriate electrical enclosure.
- വോളിയം ബന്ധിപ്പിക്കുകtage inputs (L1, L2, L3, N) as per your single or three-phase system configuration.
- Connect the secondary windings of the Current Transformers to the meter's CT input terminals. Ensure correct phase and direction.
- Connect the Modbus RS485 communication lines (A and B) and any pulsed output lines if required.
- After installation, the sealing hole can be used to apply a safety seal, preventing unauthorized tampഎറിംഗ്.
