7.2 Replacement Implementation Recommendations

1. Parameter migration: Record overvoltage/undervoltage thresholds, response time and other parameters of the original DGK-04F, and set identical parameters on the new device after replacement.
2. Wiring verification: 3-phase power wiring must be consistent with the original system; phase sequence errors cause false protection.
3. Function test: After replacement, perform simulated overvoltage, undervoltage and phase sequence error tests to verify normal protection functions.
4. Redundant configuration: Paired configuration is recommended for critical equipment to improve system reliability.
