- Protection rating: IP54
- Operating temperature: -25°C to +50°C
Avoid extreme humidity, flooding areas, or direct sunlight exposure when possible. Proper placement is key to safe and efficient operation.
Installation Method
The unit supports vertical, floor-mounted installation.
Please refer to Figures 1 and 2 in the product manual for detailed dimensions and installation positions.
Common Problems and Solutions
Even the best EV charging systems may face technical hiccups. Here’s how to handle the most common issues safely and effectively.
| No. | Common Issue | Solution |
|---|---|---|
| 1 | Circuit breaker damage | Replace the breaker immediately to restore electrical safety. |
| 2 | Data acquisition board failure | Contact the manufacturer for replacement. Avoid disassembling it yourself to prevent secondary damage. |
| 3 | Charger module failure | Replace the faulty module to restore system stability. |
| 4 | System error reports | Could be caused by module or data board faults. Contact the manufacturer for full diagnostics. |
| 5 | Platform not connecting to the internet | Restart the charger, wait for it to power down, and allow the gun to unlock automatically. If it still doesn’t release, contact customer service for assistance. |
| 6 | Current meter doesn’t display charging current | Check network cables and connections. If the communication board is damaged, it will need replacement. |
| 7 | AC undervoltage | Verify wiring and switches in the power distribution cabinet for any faults. |
| 8 | Energy meter displays zero | Unplug and reconnect the data cable. If the issue persists, replace the monitoring board. |
| 9 | Card lock issue | Always complete payment after charging. If your card gets locked, reinsert it into the same charger to unlock. |
| 10 | Charging interruption | Ensure your IC card balance is sufficient before charging. Low balance may cause charging to stop automatically. |
Module Indicator Lights: What They Mean
Each charger module has three indicator lights to show its operating status:
| Indicator Light | Normal Status | Fault Status | Fault Description |
|---|---|---|---|
| Fault Description (Green) | On | Off | No input voltage; the module cannot operate. |
| Protection Indicator (Yellow) | Off | On | Overvoltage, undervoltage, overtemperature, or communication failure. |
| Off | On | Manual mode enabled. | |
| Fault Indicator (Red) | Off | On | Output overvoltage, address conflict, or severe current imbalance. |
| Off | Flashing | Fan failure detected. | |
Understanding these lights helps you spot potential issues before they affect performance.
