Installation and maintenance:

Before installing the ABB REF615C_C HCFFAEAGANB2BAN1XC, verify the auxiliary power supply parameters to ensure compatibility with the relay’s wide-range input (24-250 V AC/DC). Check busbar configuration and connected equipment to determine appropriate CT sizing and connection schemes, ensuring accuracy of differential protection. For hybrid installations, confirm compatibility between existing SCADA protocols and the relay’s communication capabilities.

Ensure the mounting location provides adequate protection from environmental factors—while ruggedized, the relay performs best with proper enclosure in extremely dusty or humid environments. Allow 80mm clearance for ventilation and verify panel cutout dimensions (144x144mm) if using panel mount. For IEC 61850 integration, validate network infrastructure capacity and time synchronization sources to ensure reliable GOOSE messaging.

For maintenance, conduct monthly visual inspections of status indicators and review event logs using PCM600 software. Quarterly, check CT connections for tightness and corrosion, particularly in industrial environments with high humidity. Annually, update firmware to access the latest protection algorithms and security patches, and validate protection settings against current system loads.

Perform primary injection testing every two years to verify differential protection operation, and calibrate analog inputs if necessary. Conduct annual cybersecurity reviews, including password updates and verification of access control lists, to maintain IEC 62443 compliance. In harsh environments, inspect the relay’s physical condition semi-annually for signs of dust accumulation or environmental damage.
