Product Usage Instructions

1. Installation: Ensure the rack or housing is powered down before insertion. Align the board with the guide rails of the chassis and push firmly until the connectors seat properly. Use the captive screws to secure the faceplate.

2. Configuration: Access the board parameters via the ABB PCM600 (Protection and Control IED Manager) software. Ensure the firmware version matches the existing system requirements.

3. Electrostatic Safety: Always wear an anti-static wrist strap when handling the board to prevent damage to sensitive CMOS components.

4. Maintenance: Periodically check the diagnostic LEDs on the front panel. A steady green LED indicates healthy operation, while red or flashing amber indicates a hardware or configuration fault.
