Operational Precautions
- Interlocking Logic: Always verify the interlocking logic in the configuration software (PCM600) before commissioning to prevent accidental operation of disconnectors or breakers.
- Secondary CT Circuits: Never disconnect the secondary circuit of a current transformer while the primary is under load. Use shorting blocks to avoid lethal high-voltage surges.
- Power Supply Integrity: Ensure the auxiliary power supply stays within the rated range (110-250V DC) to prevent unexpected reboots during grid disturbances.
- Cyber Security: Change default passwords and disable unused communication ports (FTP, HTTP) following installation to comply with NERC CIP or local security standards.
FAQ (Questions & Answers)
Q: Does the REC670 support “Select-Before-Operate” (SBO)? A: Yes, the IED supports the SBO procedure for both local and remote control to ensure that only the intended primary equipment is operated.
Q: Can this unit handle synchro-check for multiple breakers? A: Absolutely. The REC670 can be configured to perform synchronizing, sub-network matching, and energized/de-energized line checks for several switching devices.
Q: What is the purpose of the 1MRK004814-AC code? A: This order code defines the hardware build, including the number of I/O boards, the type of human-machine interface (HMI), and the specific communication modules installed.
