E17 error; charger indicates 'Time Sync Error' or 'RTC Fault'; may affect scheduled charging.

Safety first: This is a low‑risk fault but may prevent scheduled charging from working correctly.

• Step 1 – Network check: Ensure the charger is connected to Wi‑Fi so it can sync time from the Electrify America cloud.
• Step 2 – Manual time set: Use the app or local interface to manually set the correct time and date.
• Step 3 – Power cycle: Turn OFF the breaker for 2 minutes, then ON, and verify if the time is retained.
• Step 4 – Board inspection (power OFF): Open the enclosure and locate the RTC backup battery on the control board (if present). If it is removable and clearly depleted, replace with the same type and orientation.
• Step 5 – Firmware update: Apply any available firmware updates via the app to correct potential RTC bugs.
• Step 6 – Replace control board: If the RTC continues to lose time or E17 persists, the control board may need replacement.
