Possible Causes

Open neutral connection between the generator and ATS, loose neutral bar in the generator terminal box, faulty residual current device (RCD) or earth leakage breaker, incorrect neutral‑earth bonding configuration.

How to Fix / Troubleshooting

Safety first: Isolate the generator and mains. Only a qualified electrician should work on neutral and earth connections.

  • Inspect neutral conductor: In the generator terminal box, verify that the neutral (N) conductor is securely connected and not burnt or loose.
  • Check cable to ATS: Confirm continuity of the neutral conductor from the generator to the ATS using a multimeter. Repair any breaks.
  • RCD/ELCB check: If the generator has an integrated RCD, test it using the TEST button. If it trips immediately or will not reset, replace the RCD module.
  • Verify bonding: Ensure the neutral‑earth bonding arrangement matches Einhell and local code requirements (floating neutral vs. bonded). Incorrect bonding can trigger E13 on some controllers.

Improper neutral/earth configuration can be hazardous. Have an electrician verify the installation if you are unsure.
