How to Fix / Troubleshooting
Safety first: Turn off power before touching internal metering components.
- Compare readings: Note the difference between EVlink and vehicle-reported power/energy. Small differences are normal; large discrepancies indicate a fault.
- Inspect CTs: With power OFF, verify that current transformers are clamped around the correct conductors and oriented according to arrows or markings.
- Check wiring: Ensure CT secondary leads are firmly connected to the metering board and not swapped between phases.
- Firmware update: Consult Schneider Electric for any firmware updates addressing metering accuracy.
- Meter replacement: If inaccuracies persist, the internal meter module may need replacement by a technician.
