Replace the Faulty Power Board or Socket Board

Safety Precautions: This procedure must only be performed by a qualified electrician. Ensure the charging station is fully disconnected from the main power supply at the circuit breaker before beginning. Verify the absence of voltage with a calibrated multimeter.

1. Open the charging station housing to access the internal components.
2. Locate the defective Power Board (NG) or Socket Board (AHP) that failed the relay startup test.
3. Carefully disconnect all wiring harnesses and cabling attached to the board, noting their original positions for reassembly.
4. Unscrew and remove the damaged board from the mounting chassis.
5. Install the replacement board, ensuring it is securely fastened in the original orientation.
6. Reconnect all wiring harnesses and cables to their correct pin headers, verifying that connections are firm and undamaged.
7. Close the housing and restore power to the unit at the circuit breaker.
8. Verify the repair by monitoring the startup sequence; listen for two distinct, audible relay clicks within one second to confirm the new board is functioning correctly.
