To establish a proper connection, first locate the terminals: one for the power feed, one for the neutral, and one for the ground. Begin with the black terminal for the main power source, followed by the white terminal for the neutral return path.
Ensure the system is completely powered off before proceeding. This safety step prevents electrical hazards and ensures accurate connections. After confirming the circuit is de-energized, connect the power source to the designated terminal first.
Next, attach the neutral conductor to the corresponding terminal. This conductor ensures that electrical current returns safely to the panel. Lastly, connect the grounding conductor to the ground terminal, which prevents potential electrical surges or faults.
Double-check each connection to ensure no exposed wires are left loose. Secure all terminals and make sure the connections are tight. Once complete, power the system back on and test the functionality to verify everything is working correctly.
Coil Wiring Guide
Begin by identifying the three primary conductors: the live, neutral, and ground leads. The live conductor usually comes in black, the neutral in white, and the ground in green or bare copper. Connect the live wire to the designated terminal for power, ensuring it’s securely attached to prevent contact issues.
Step 1: Power Terminal Connection

The live lead should always be connected first to the terminal marked for power. This will allow the current to flow to the rest of the system. Ensure that no exposed copper is visible after making the connection, as this can lead to short circuits or electrical hazards.
Next, attach the neutral conductor to its respective terminal. This is necessary for completing the circuit, as the neutral wire provides the return path for the current. Make sure the connection is tight and that the wire insulation is undamaged.
Step 2: Grounding the System
Ground the system by connecting the green or bare wire to the designated ground terminal. This step is vital for safety, as it helps prevent electrical shocks and directs excess current away from sensitive components in case of a fault.
Once all connections are secure, check for any loose ends or exposed wires. Re-test the system before securing it in place to confirm that the connections are functioning properly. After verifying that everything works, complete the installation and restore power to the circuit.
How to Identify Coil Terminals and Functions
First, locate the primary terminals: power, neutral, and ground. The power terminal is typically marked in black or red and is responsible for the main current flow. The neutral terminal, usually white, completes the circuit and provides the return path for the current. The ground terminal is often green or uninsulated and ensures safety by directing excess electricity safely away.
Power and Neutral Terminals

The power terminal handles the incoming live current and must be securely connected to prevent electrical hazards. The neutral terminal connects the return path and is key for completing the electrical circuit. Always ensure that both connections are tight and properly insulated to avoid shorts or faults.
Grounding
- The ground terminal protects against electrical surges and faults by safely redirecting excess current.
- It is often connected to the metallic housing of the device to prevent shock hazards.
