Wiring Instructions
Level 1 Charging
If a power distribution box is being used, make sure to connect the L (Line), N (Neutral), and PE (Protective Earth) ends of the input cable of the plug to the corresponding L, N, and PE ends of the circuit breaker respectively.
Level 2 Charging
If a power distribution box is being used, make sure to connect the L1, L2 (Line 1 and Line 2), and PE (Protective Earth) ends of the input cable of the plug to the corresponding L1, L2, and PE ends of the circuit breaker respectively.
Display Screen Description
The display screen shows the charging status. Key information includes:
- Charged Power
- Charging Time
- Voltage
- Current
- Power

Troubleshooting
Excessive Leakage Current
| Problem | Causes | Possible Solutions |
|---|---|---|
| Excessive Leakage Current | Excessive Leakage Current | 1. Please disconnect the leakage or over-current protection switch on the distribution box immediately. |
| 2. Please check whether the AC charger output line is damaged or has low impedance to the ground or a short circuit. | ||
| 3. Please inspect the inlet socket of the vehicle to ensure it is in good condition. | ||
| 4. Once the above issues have been addressed, please attempt to power on the system again. If the problem persists, please do not hesitate to contact Tera for further assistance. | ||
| AC Over-current | High Input Current | 1. Please immediately disconnect the leakage/over current protection switch from the distribution box. |
| 2. Please check if there is a low impedance or a short circuit between the two output lines of the AC charger. | ||
| 3. After troubleshooting the issues mentioned above, please attempt to power the system on again. If the problem persists, please contact Tera for further assistance. | ||
| Ground Fault | Ground fault circuit interruption | 1. Please immediately disconnect the leakage/over current protection switch from the distribution box. |
| 2. Please check whether the input/output line of the AV charger is properly grounded or not. | ||
| 3. After troubleshooting the issues mentioned above, please attempt to power on the system again. If the problem persists, please contact Tera for further assistance. | ||
| AC Under-voltage | Low Input Voltage | 1. If the voltage drops below 190Vac for level 2 or 90Vac for level 1 for a brief period of time, the charger will go into standby mode and check the power network to restore itself to the normal voltage range. Once the voltage is within normal range, the charger will automatically resume charging. |
| 2. If the voltage in your area/community remains consistently low (below 190Vac for level 2 or 90Vac for level 1) for an extended period of time, please wait to use the charger until the voltage recovers back to the normal range. | ||
| AC Over-voltage | High Input Voltage | 1. If the voltage surpasses 270Vac for level 2 or 140Vac for level 1 for a short duration, the charger will enter standby mode and conduct a power network check to restore itself to the normal voltage range. Once the voltage is within normal range, the charger will automatically resume charging. |
| 2. If the voltage in the local area or community remains over 270Vac for level 2 or 140Vac for level 1 for a prolonged period, the user should refrain from using the charger until the voltage returns to the normal range. | ||
| Relay Failure | Relay Failure or Adhesion | 1. Try restarting the charger and allow it to run its internal self-diagnostic and repair routines. |
| 2. If the problem persists even after restarting the charger, please do not hesitate to contact Tera for further assistance. | ||
| CP/CC Error | Charger CP/CC Connection Error | 1. Please check whether the charging plug is securely and firmly connected to the vehicle's inlet socket. |
| 2. If the problem persists, please do not hesitate to contact Tera for further assistance. |
