• Scenarios requiring reliable power supply such as industrial parks, manufacturing industry, petrochemical industry and mining industry.
• Integration with upper-level systems like ABB 800xA and System 800 to achieve global monitoring and remote diagnosis.

Installation Key Points

1. On-site Environment: Ensure that the operating temperature and humidity comply with specifications (-40 °C to +70 °C) and avoid strong magnetic field interference.
2. Power Wiring: Use a 24 V DC regulated power supply and follow the polarity markings in the wiring diagram.
3. Measurement Circuit: Voltage transformers (VT) and current transformers (CT) shall be correctly selected according to the rated ratio and firmly installed.
4. Communication Wiring: Lay optical fibers or copper cables according to the selected protocol (e.g., IEC 61850) and keep the ports clean.
5. Cabinet Installation: Adopt a standard 19-inch cabinet and reserve sufficient heat dissipation space; avoid over-tightening screws to prevent cabinet deformation.
6. Grounding: All metal enclosures must be reliably grounded to prevent electric leakage and electromagnetic interference.

Maintenance Recommendations

1. Regular Inspection: Check CT/VT connections, terminal tightness and cabinet cooling holes for blockage every 6 months.
2. Firmware Upgrade: Obtain the latest firmware through the ABB remote service platform to enhance functions and security.
3. Self-Test Function: Use the built-in Self‑Test function to verify the status of internal hardware; the system will display error codes on the HMI in case of anomalies.
4. Spare Parts Management: Keep power supply modules, communication cards and HMI display screens in stock for quick replacement.
5. Log Storage: Regularly export event logs and trend data for subsequent analysis and fault tracing.
