Frequently Asked Questions
Q: Does this unit support hot-swapping? A: No. These IEDs need the system powered down for safe replacement. The bus architecture and power requirements prevent live insertion without risk of disruption.
Q: Is the RED670 series obsolete and what replacements exist? A: Yes, many variants have reached end-of-life. Direct migration paths usually go to newer Relion 670 or 650 series versions. Always match firmware and re-validate all protection settings.
Q: Will I lose my program during replacement? A: Not if you back it up properly first. Use PCM600 to export the complete configuration before swapping. Reload and test the settings on the new unit to avoid mismatches.
Q: Are these factory-new or refurbished? A: These come as new original surplus. We trace them through proper channels. Each one goes through full functional testing on a relay test bench plus extended load checks.
Q: What warranty and lead times do you offer? A: Standard 12-month warranty from delivery. Units typically ship in 1-3 business days when in stock. Confirm exact power supply and I/O options match your panel before purchase.
