Understanding the Power Supply

A power supply has two main sections: the input and the output. Familiarizing yourself with these sections is the first step in making safe and correct connections. Each wire has a specific function:

Input Side:

• Green/Yellow wire: Ground
• Brown wire: Live (hot)
• Blue wire: Neutral

Output Side:

• Red wire: Positive
• Black wire: Negative

These labels help you match the wires correctly during installation.

Connecting the Power Supply Input

To connect the power supply to your main power source, follow these steps:

1. Identify the Input Wires: On the input side, you’ll see three wires: ground (green/yellow), live (brown), and neutral (blue).
2. Connect to Power: You can either use a three-pin plug for easy connection to an outlet or directly connect the wires to a breaker switch if it’s part of a dedicated circuit.

Connecting the Power Supply Output

On the output side, the power supply has two wires:

1. Red Wire (Positive): This is the positive output.
2. Black Wire (Negative): This is the negative output.

Make sure these are correctly matched with the corresponding wires on the gas price sign.

Connecting the Gas Price Sign to the Power Supply

The gas price sign has two primary wires, which may be either brown and blue or red and black. Regardless of color, the function is consistent:

• Red or Brown: Positive (Hot)
• Blue or Black: Negative (Neutral)

To connect the power supply output to the gas price sign:

1. Match the Wires: Connect the positive wire from the power supply output to the positive wire on the sign and the negative wire to the negative wire on the sign.
2. Secure the Connections: Use appropriate connectors to secure the wiring.

Using a Junction Box for Secure Connections

For added protection, use a junction box to house and protect the wire connections:

1. Simple Junction Box: Pass the cables through and secure them with wire nuts or connectors.
2. Terminal Junction Box: Choose a junction box with a terminal bracket for easier and more organized connections, especially helpful for protecting against weather elements.

Final Tips

• Always double-check your connections for accuracy.
• Ensure the connections are tightly secured to prevent disconnections or short circuits.
• Use protective enclosures like junction boxes to safeguard connections from environmental elements.
