　　Installation & Operational Guide

　　Proper installation is crucial for the safe and effective operation of the HVP-4000. Follow these steps to set up your system.

　　Pre-Installation Checklist

　　Before powering on the unit, ensure you have:

　　A stable and level mounting surface (vehicle roof, tripod, or ground platform).

　　A compatible AC power source (generator, vehicle inverter, or grid power) that can sustain a 4000W+ load.

　　The certified high-voltage tether cable, inspected for any signs of damage.

　　Appropriate personal protective equipment (PPE) for high-voltage systems.Step-by-Step Installation Procedure

　　Secure the Power Supply: Mount the HVP-4000 unit securely using the provided brackets. Ensure it is firmly fastened to prevent movement during operation or transit.

　　Connect to AC Power Source:

　　Use a heavy-duty, outdoor-rated power cable to connect the HVP-4000's INPUT port to your AC source (e.g., a generator).

　　Crucial: Verify that the AC source voltage and frequency are within the specified input range (90-264V AC, 50/60 Hz).Deploy the Tether System:

　　Carefully unspool the tether cable, avoiding sharp bends or kinks. A minimum bend radius of 5cm is recommended.

　　Connect the tether's ground-side connector to the HIGH-VOLTAGE OUTPUT port on the HVP-4000 until it clicks and locks securely.

　　Route the tether away from the immediate launch area to avoid propeller interference.Connect to the Drone:

　　Power on your tethered drone.

　　Connect the airborne end of the tether to the drone's power input port. Ensure a secure and locked connection.Power On Sequence:

　　Turn on the AC power source (e.g., start the generator).

　　Switch the HVP-4000 to the "ON" position. The system will perform a brief self-check. The status indicator will show a steady green light upon successful initialization.Commence Operation: Once the HVP-4000 indicates a "Ready" status, you may proceed with the standard drone take-off procedures. The unit will now automatically supply power.Tether Management Best Practices

　　Always use a tether management system (TMS) or winch to manage cable tension and prevent slack from endangering the drone or people on the ground.

　　Never operate the system with a damaged or frayed tether cable.

　　Regularly inspect connectors for wear, corrosion, or bent pins.

　　Our Commitment: Rigorous Quality Control

　　Every HVP-4000 unit is a product of a meticulous, multi-stage quality control process designed to meet the highest industrial standards.

　　Design and Component Sourcing

　　We use only industrial-grade components from certified suppliers (e.g., TDK, Murata, Infineon).

　　All printed circuit boards (PCBs) are designed to IPC-A-610 Class 2/3 standards for reliability.In-Line Production Testing

　　Automated Optical Inspection (AOI): Checks for soldering defects and component placement accuracy on all PCBs.

　　In-Circuit Testing (ICT): Verifies the electrical performance of individual components and circuits

　　Ensuring Longevity: Inspection & Maintenance Schedule

　　Proactive inspection and maintenance are key to the long-term reliability of your power supply.

　　Daily/Pre-Flight Inspection

　　Visually inspect the unit's casing for cracks or physical damage.

　　Check all cable connectors (both input and output) for secure fit and absence of corrosion.

　　Inspect the entire length of the tether for cuts, abrasions, or kinks.

　　Ensure the cooling vents are clean and unobstructed.Monthly Maintenance

　　Clean the exterior with a soft, dry cloth. If necessary, use a cloth lightly dampened with fresh water. Do not use solvents.

　　Use compressed air to gently remove dust from the internal heatsink and fan blades (requires opening the case; only to be performed by qualified personnel).

　　Verify fan operation by listening for smooth, unobstructed spinning during operation.Annual Professional Servicing

　　We recommend sending the HVP-4000 unit back to an authorized service center for a comprehensive annual service. This includes:

　　Internal visual inspection for damaged components or capacitors.

　　Re-calibration of output voltage and current sensors.

　　Firmware update (if applicable).

　　Full functional re-test under load.
