Possible Causes
Missing phase on three-phase supply, Blown upstream fuse on one phase, Loose phase conductor in EVlink terminal block, Faulty phase detection circuit on control board
How to Fix / Troubleshooting
Safety first: Three-phase circuits can be extremely hazardous. Only qualified personnel should work on them.
- Check upstream protection: Inspect the three-phase breaker or fuses feeding the EVlink charger. Replace any blown fuses and investigate the cause.
- Verify wiring: With power OFF, confirm that all three phases (L1, L2, L3) and neutral (if required) are correctly connected and firmly tightened at the EVlink terminal block.
- Measure phase voltages: An electrician should measure L1–L2, L2–L3, and L3–L1 to ensure balanced voltages within specification.
- Test operation: After correcting supply issues, restore power and attempt a charge. If E09 persists, the phase detection circuitry on the control board may be faulty.
- Board replacement: Have a Schneider Electric–authorized technician replace the EVlink control board if phase detection is confirmed defective.
