A Step-by-Step Guide for Configuring SDM630MCT Three-Phase Meter DIN Mounted Meter

A Step-by-Step Guide for Configuring SDM630MCT Three-Phase Meter DIN Mounted Meter

Today, DIN Rail power meters have become essential components in industrial control systems. A secure and reliable mounting system capable of withstanding heavy vibration makes DIN Rails a demanding piece of equipment in the electrical manufacturing sector. DIN Rail meters need to meet all the safety and security standards aptly, being a viable component for the installation, maintenance, and operation of other electrical devices. Additionally, the correct configuration can prevent any hazardous accidents. Also, faulty installation can impair the device from sharing accurate energy usage data. 

Among the top DIN Rail manufacturing companies, Eastron Europe’s metering devices are best known for their quality features, compact design, and reliable and safe usage. 

Eastron Europe specialises in portable and compact DIN Rail-mounted meters with a simple installation process to give customers an overall frictionless experience.

How to Install Three-Phase DIN Rail Mounted Meters?

The configuration video for DIN Rail metering device SDM630MCT will guide you through correct wiring and setting up a three-phase meter with a current transformer (CT). 

Here’s a step-by-step process to install a mounted meter like SDM630MCT. 

Step 1: Understanding the Model and Its Parts

  1. SDM stands for Sub Distribution Meter
  2. 630 represents the 3 Phase meter range
  3. M indicates Modbus 485 serial communication interface
  4. CT signifies current transformer
  5. The CT is connected to each phase for current flow measurement

Step 2: Meter Orientation and Power Connections 

  1. You can locate the voltage reference terminals at the bottom of the meter
  2. Terminal 1: Neutral
  3. Terminal 2: L3
  4. Terminal 3: L2
  5. Terminal 4: L1
  6. Supply these terminals with 3-phase power via an inline 1A fast blow fuse for each phase
  7. Connect auxiliary power supply
  8. Terminals 5 and 6 are used to power the meter itself
  9. The auxiliary power is either supplied via a circuit breaker or linked to terminals 1 and 4
  10. Terminal 7 (Live) and terminal 8 (Neutral) can be used to power other meters or loads

Step 3: CT and Modbus Connections 

  1. Locate terminals for pulse output, Modbus, and CT connections on the top of the meter
  2. Connect CTs
  3. Terminals 15-20 are for CT connection
  4. Connect Phase L1 CT to terminals 19 (S2) and 20 (S1)
  5. Connect Phase L2 CT to terminals 17 (S2) and 18 (S1)
  6. Connect Phase L3 CT to terminals 15 (S2) and 16 (S1)

Step 4: Setting CT Rate 

  1. Determine the CT rate based on your CT specifications
  2. Example: CT rated with an input of 200 Amps and output of 5 Amps, CT rate = 200/5 = 40
  3. Enter CT settings
  4. Hold down the E button
  5. Enter password 1000 by using Up/Down button
  6. Use ‘Enter’ to move the cursor
  7. Scroll through the menu until you see CT2
  8. Set CT2 output/secondary to match CT (e.g., 5 Amp)
  9. Set CT rate to desired value (e.g., 40)

Step 5: Modbus and Pulse Output Connections

  1. Terminals 12 GND, 13 B, and 14 A are for Modbus RS485 communication
  2. Terminals 9, 10, and 11 are for pulse output

Step 6: Final Checks 

  1. Ensure all CTs are rated the same and connected correctly
  2. Connect CTs to the correct terminals (S1 and S2)
  3. Orient CTs correctly on phase conductors (arrow denotes current flow direction)
  4. Ensure CT connections to the meter are correctly colour-oriented (black to S2, white to S1)
