Charger intermittently stops charging; app logs E005 – Undervoltage detected; LED ring shows red/blue pattern.

Safety first: Work on live circuits only if you are qualified. Otherwise, call an electrician.

• Check breaker and cable size: Confirm the dedicated circuit breaker and cable cross-section meet NewMotion’s installation requirements for the configured current (e.g., 6 mm² for 32 A, depending on local code and run length).
• Measure voltage under load: With the charger attempting to charge, measure the voltage at the charger’s input terminals. If it drops significantly below nominal (e.g., <207 V on a 230 V system), the supply is inadequate.
• Tighten connections: Isolate power, then tighten all line and neutral screws on the charger’s terminal block and in the upstream distribution board.
• Reduce current setting: In the installer configuration (via app or web portal), temporarily reduce the maximum charging current and see if E005 events stop. This can confirm a supply limitation.
• Investigate shared loads: Ensure the charger is on a dedicated circuit and not sharing with high-load appliances that cause voltage sag.
• PCB check: If supply is stable but E005 persists, the voltage sensing section of the main PCB may be misreading and need replacement.
