ABB B-Range Electrical Meters
This guide will show you how to connect the Polar Monitoring Gateway to the ABB B-Range electricity meters. It will also take you through the setup and parameters required on the electricity meters to ensure communications to the Polar Gateway.
Steps to Follow:
- Connect power to the Gateway.
- Connect RS-485.
- Final checks.
- Power on the system.
- Configure the ABB Meter’s Serial Parameters.
ABB B-Range Connection Setup
1. Connect power to the Gateway.
Wire the Polar Gateway to a 12-24 V DC power supply. Connect the positive wire to the positive terminal and the negative wire to the negative terminal.
2. Connect RS-485.
Connect the Modbus cable to allow communication with the Polar Gateway. Connect A+ to B+ on the meter and the B- to A- on the meter.
3. Final checks
- Make sure the wiring is secure – no short circuits.
- Check if the power cables are not loosely wired to the Gateway.
- Check if the power cables are not loosely wired to the device.
- Re-check the RS-485 twisted pair cable is correctly wired.
4. Power on the system.
Now you are ready to go, you can now switch on the Polar Gateway and the ABB B-Range.
5. Configure ABB B-Range Serial Parameters
Note: It is critical to change the default settings to reflect the table below.
