Possible Causes
Missing phase at input terminal, Blown upstream fuse on one phase, Incorrect phase rotation, Loose phase conductor in terminal block
How to Fix / Troubleshooting
Safety warning: Three‑phase work must be done by a qualified electrician.
- Verify supply phases: Using a multimeter, check voltage between all phase pairs at the charger input. Any missing or low voltage indicates an upstream issue.
- Inspect terminal block: With power OFF, tighten all phase conductor screws and look for heat damage.
- Check upstream protection: Inspect fuses or breakers feeding each phase and replace any blown fuses with the correct rating.
- Phase sequence: If the charger requires a specific phase rotation, swap phases at the input as per the installation manual.
- If wiring is correct but E19 persists: The phase monitoring circuit on the main control board may be defective.
