Resolve Wall Connector Grounding Faults via Professional Electrician

Safety Warning: This procedure involves high-voltage electrical systems. Do not attempt to open the Wall Connector or service the electrical panel yourself. Only a licensed, qualified electrician should perform these steps.

1. Professional Inspection: Engage a licensed electrician to inspect the entire installation path from the main service panel to the Wall Connector.
2. Verify Grounding Path: The electrician must verify that the grounding conductor is continuous and properly bonded to the building’s main grounding system.
3. Measure Voltage: Using a calibrated multimeter, the electrician must verify voltage readings at the Wall Connector terminal block, specifically checking L1 to L2/N, L1 to Ground, and L2/N to Ground to ensure they meet local electrical code specifications.
4. Inspect Connections: Check all electrical terminals, junction boxes, and panel connections for looseness, corrosion, or signs of overheating, and ensure all connections are torqued to manufacturer specifications.
5. Verify DIP Switch Settings: Confirm that the internal DIP switches are configured correctly for the specific installation environment and local electrical supply.
6. Verify Main Panel Bond: Ensure the neutral and ground are correctly bonded at the main service panel according to residential electrical standards.

Verification: Once the electrician has corrected any identified wiring or grounding faults, reset the Wall Connector power at the circuit breaker. The CC_a001 alert should clear, and the unit should return to a ready-to-charge state.
