2. Safety Information

Observe the following safety precautions to prevent injury or damage to the device:

• Ensure the input voltage is within the specified range of DC 11-90V. Exceeding this range can damage the converter.
• Do not exceed the maximum output current of 6A. Overloading the converter can lead to overheating and failure.
• Verify correct polarity before connecting the input and output wires. Incorrect wiring can cause severe damage to the converter and connected devices.
• Install the converter in a well-ventilated area, even though it features good heat dissipation.
• Avoid short-circuiting the output terminals. The converter has short-circuit protection, but prolonged short circuits should be avoided.
• Keep the device away from flammable materials during operation.
• If the device shows signs of damage or malfunction, disconnect power immediately and do not attempt to repair it.

5. Setup and Installation

Follow these steps for proper installation:

1. Prepare Wiring: The converter comes with pre-attached wires. Identify them as follows:
   • Input: Red wire (Input +), Black wire (Input -)
   • Output: Yellow wire (Output +), Black wire (Output -)
2. Mounting: Securely mount the converter in a suitable location using the integrated mounting holes. Ensure it is protected from excessive mechanical stress.
3. Connect Input: Connect the Red wire (Input +) to the positive terminal of your DC power source (11-90V). Connect the Black wire (Input -) to the negative terminal of your DC power source. Ensure connections are firm and insulated.
4. Connect Output: Connect the Yellow wire (Output +) to the positive input of your 5V device. Connect the Black wire (Output -) to the negative input of your 5V device. Double-check polarity before applying power.
5. Verify Connections: Before applying power, visually inspect all connections to ensure correct polarity and secure wiring.

8. Maintenance

The DROK Waterproof DC to DC Buck Converter is designed for minimal maintenance due to its robust and sealed construction. However, consider the following:

• Periodically inspect the wiring for any signs of wear, corrosion, or loose connections.
• Ensure the converter's casing is free from excessive dirt or debris that could impede natural cooling. Clean with a soft, dry cloth if necessary.
• Do not open the casing, as this will void the waterproof rating and potentially damage internal components.

9. Troubleshooting

If you encounter issues with your converter, refer to the following:

• No Output Voltage:
  • Check if the input voltage is present and within the 11-90V range.
  • Verify input polarity (Red to +, Black to -).
  • Check for any short circuits on the output.
  • Ensure the load does not exceed 6A.
• Converter Overheating:
  • Reduce the load current to ensure it is within the 6A limit.
  • Ensure adequate ventilation around the converter.
  • Verify the ambient temperature is within the specified operating range (-25℃ to 80℃).
• Connected Device Malfunctions:
  • Confirm the connected device requires 5V DC.
  • Check output polarity (Yellow to +, Black to -).
  • Ensure the device's current draw is not fluctuating excessively.

If problems persist after checking these points, contact DROK customer support.
