First, use a test light to locate the live wire.
2. Turn off the power to the electrical outlet.
Plug one end of the fire wire into one of the two holes marked A, then pull out a 2.5MM2 insulated wire from the other hole and securely connect it to the L hole in the lower outlet.
4. Ensure the N terminal is securely connected to one of the three holes in the power outlet; Aviation ground power 2, 36V aviation power 1, 400Hz variable frequency power supply 7, 115/200V power supply 2, 27V DC power supply 5, 400Hz power supply 12, aviation power supply
5. Securely connect the E hole within the three-prong socket directly to the earth wire. Note: Do not mix up the neutral and earth wires (usually left for neutral, right for hot, and bottom for earth), otherwise, when electrical equipment is plugged in, it will trip the circuit breaker upon activation.
