Q1: What should I do if the charging fails to start?
Please check the physical connection first. Ensure the charging gun is fully inserted until you hear a "click" locking sound. Also, verify that the gun head and vehicle port are free from foreign objects or oxidation.
Q2: How do I resolve a communication handshake failure?
This may be due to incompatible protocols between the vehicle's BMS and the charger. Ensure the vehicle has completed operator authentication if required. Check the pile screen for "Communication timeout" messages.

An insulation fault is a safety protection trigger. It indicates the system has detected a potential leak or moisture. Ensure the charging environment is dry and re-plug the connector after checking for cleanliness.
Q4: Can this charger be used in extreme temperatures?
Yes, the device is designed to operate within an environment temperature range of -25℃ to +45℃, with natural air cooling for efficient heat dissipation.
Q5: What information is displayed on the charging screen?
The display provides real-time data including charge voltage, current, total quantity charged, and specific fault codes for troubleshooting.
Q6: What are the installation options for the 7kW model?
The unit offers flexible installation modes: it can be column-mounted (floor type) for public spaces or wall-mounted for more compact environments.
