Installation Instructions

First, disconnect the power supply. Then, identify the positive and negative contacts with a multimeter.

Connect the wires to the corresponding points in your circuit. After that, insulate every soldered or joined connection with heat-shrink tubing or suitable electrical insulation.

Finally, check the voltage and polarity before connecting sensitive equipment.

Important Notes

• Confirm that both devices use a 5.5 x 2.1mm connector.
• A 5.5 x 2.5mm connector may look similar but may not provide a reliable connection.
• Do not determine polarity from the connector shape alone.
• Verify wire polarity with a multimeter before use.
• Do not rely only on the red and black wire colors.
• Check the required voltage and current of the connected device.
• Do not exceed the safe current capacity of the attached wires.
• Use this pair only with suitable low-voltage DC circuits.
• This product does not regulate or convert voltage.
• Keep all exposed wire joints properly insulated.
