Setup Instructions

1. Verify Compatibility: Before connecting, ensure your device (e.g., Mediasonic ProBox/ProRaid enclosure) requires a 12V DC input and has a compatible 4-pin DIN power port.
2. Connect AC Power Cord: Insert the C7/C8 connector of the AC power cord firmly into the corresponding port on the Kircuit AC/DC adapter's power brick.
3. Connect to Device: Plug the 4-pin DIN connector of the adapter's DC output cable into the power input port of your Mediasonic external hard drive enclosure. Ensure a secure connection.
4. Connect to Wall Outlet: Plug the AC power cord's 2-prong plug into a standard, grounded wall outlet.
5. Power On: Once all connections are secure, power on your device if it has a separate power switch. The adapter's indicator light (if present) should illuminate, indicating power is being supplied.

Operating Instructions

Once properly connected, the Kircuit 4-Pin 12V AC/DC Adapter will continuously supply power to your compatible device. No further operational steps are required for the adapter itself. Ensure your device is powered off before disconnecting the adapter to prevent data loss or damage.

Maintenance

To ensure the longevity and optimal performance of your adapter:

• Keep the adapter clean and free from dust. Use a dry, soft cloth for cleaning.
• Store the adapter in a cool, dry place when not in use.
• Avoid bending or crimping the cables excessively, as this can damage internal wires.
• Regularly inspect the cables and connectors for any signs of wear or damage. Replace the adapter if any damage is observed.

Troubleshooting

If you encounter issues with your Kircuit AC/DC Adapter, consider the following:

• No Power to Device:
  • Check if the adapter is securely plugged into both the wall outlet and your device.
  • Ensure the wall outlet is functional by testing it with another appliance.
  • Verify that the AC power cord is fully inserted into the adapter's power brick.
  • Confirm that your device's power switch (if any) is in the 'ON' position.
• Device Powers On Briefly Then Shuts Off:
  • This may indicate an incompatibility or insufficient power delivery. Double-check that your device's power requirements (voltage and amperage) precisely match the adapter's output specifications.
  • Ensure the adapter is rated for the correct voltage (12V) and has sufficient current (Amps) for your specific Mediasonic model.
• Adapter Feels Hot:
  • A slight warmth is normal during operation. However, if the adapter becomes excessively hot, unplug it immediately. This could indicate an overload or internal fault.
  • Ensure the adapter is in a well-ventilated area and not covered.

If problems persist after troubleshooting, discontinue use and contact customer support.
