Figure 1: Kircuit AC Power Cord. This image shows the black power cord coiled, with a standard two-prong US plug on the left and a C7 figure-8 connector on the right, designed for various electronic devices.
The Kircuit AC Power Cord is a replacement or spare power cable, ensuring your equipment receives stable power from standard electrical outlets. It features a durable construction and is built with internal components for protection against overcharge and dynamic IC management.
Safety Information
- Always ensure the power cord is fully inserted into both the wall outlet and the device's power input.
- Do not use the power cord if it is damaged, frayed, or has exposed wires.
- Avoid placing heavy objects on the power cord or bending it sharply.
- Keep the power cord away from water, excessive heat, and direct sunlight.
- Disconnect the power cord from the wall outlet before cleaning or moving the device.
- This power cord is designed for indoor use only.
Setup
- Identify Compatible Device: Ensure your device requires a C7 (figure-8) power connector and operates within the 100V-240V AC input range. This cord is compatible with various Rohde & Schwarz Spectrum Analyzer Series (e.g., FSQ, FSL, FSU, FSV, FSW, FSP, FPC, FSEA, FSEB, FSEK, FSEM, FSVA, FSIQ) and UPV/UPV66 Audio Analyzers.
- Inspect the Cord: Before first use, visually inspect the entire length of the power cord for any signs of damage, cuts, or kinks. Do not use if damaged.
- Connect to Device: Locate the power input port on your Rohde & Schwarz device. Align the C7 connector (the figure-8 end) of the Kircuit power cord with the device's input and push firmly until it is fully seated.
- Connect to Power Outlet: Insert the two-prong plug end of the power cord into a standard 100V-240V AC wall outlet. Ensure the outlet is easily accessible and not overloaded.
- Verify Connection: Once connected, ensure both ends of the cord are secure. Your device should now be ready to receive power.
Operating Instructions
The Kircuit AC Power Cord functions as a direct power supply cable. Its operation is passive, meaning it facilitates the transfer of electrical power from the wall outlet to your compatible device. There are no user-adjustable settings on the power cord itself.
- Once properly connected, the power cord will supply AC power to your device, allowing it to operate or charge its internal battery (if applicable).
- Always power off your device before disconnecting the power cord from the device or the wall outlet, especially during prolonged periods of non-use or during electrical storms.
- For optimal performance, use the power cord in a well-ventilated area to prevent overheating of the device it powers.
Maintenance
- Cleaning: Disconnect the power cord from all power sources. Use a soft, dry cloth to wipe down the cord and connectors. Do not use liquid cleaners or abrasive materials.
- Storage: When not in use, coil the power cord loosely. Avoid tight coiling or sharp bends, which can damage the internal wires. Store in a cool, dry place away from direct sunlight and extreme temperatures.
- Regular Inspection: Periodically inspect the power cord for any signs of wear, such as cracks in the insulation, exposed wires, or bent prongs. Replace the cord immediately if any damage is observed.
