5. Installation and Maintenance Guidelines
- On-Site Survey: Confirm that the chassis installation location meets IP65 protection requirements and reserve sufficient space for heat dissipation.
- Power Connection: Adopt three-way redundant power supply; ensure the main power, backup power, and UPS are properly connected, and conduct voltage/current testing.
- Wiring Specifications: Perform I/O wiring in accordance with the IEC 61800-5-1 standard; use shielded cables and ensure proper grounding.
- Communication Configuration: Configure corresponding fieldbus parameters (baud rate, node address, etc.) in ELOP-II and conduct network connectivity testing.
- Function Testing: After completing hardware wiring, perform a safety function self-test to verify redundant switching, watchdog triggering, and fail-safe output.
- Regular Maintenance:
- Check the voltage of power modules and the operation status of fans every 6 months.
- Conduct a software version audit annually to ensure the safety-certified compiler is up-to-date.
- Record all maintenance logs for traceability and auditing purposes.
