1. Using the G15 tethering box requires 3-phase AC power. For normal operation, the onboard power supply must be installed on the drone.

2. Connect the tethering cable output to the drone’s onboard power supply. Secure the hook to the load plate.

The tethering box’s high-voltage cable output uses an XT90 connector. Connect the cable to the drone’s onboard power supply as shown below and secure it.

The load-bearing hook (the cable bears the load)

1) During operation, first adjust the torque adjustment knob to the lowest setting, then close the circuit breaker to power on the system. The display on the panel will illuminate.
2) To power the drone, press the “Main Power On/Off” button. The tethered box cooling fan will begin operating, the “Main Power Running” indicator will illuminate, and the display will show the current output voltage, current, and power of the main power cable. When the system is carrying current, the indicator will flash, indicating that power is being supplied to the aircraft.
3) When the drone is ready for takeoff, adjust the torque knob to the lowest setting or Apply a slight torque (in windy conditions) and pull the cable through the drone. When reeling in the cable, adjust the torque knob from low to high, synchronizing with the drone’s descent speed. Alternatively, adjust the torque to the appropriate level from the start to maintain a constant tension in the cable. The drone will release the cable, forcing it to hover. During landing, the cable will automatically reel in due to the tension.
4) After the mission is completed, turn off the main power switch and the high-voltage DC power before reeling in the remaining cables to prevent accidental electric shock. Finally, turn off the main power switch and unplug the power cord.
3. Start the drone and fly to an altitude of approximately 5 meters. Press the main power switch. Once the device is powered on, press the main power button to start the power supply. The warning light will illuminate green, and the drone will fly upward. Turn the reel knob to straighten the cable. If the drone needs to descend, turn off the cable power when it is approximately 5 meters above the ground. Return the winch to zero and the drone will land. Product Care
1. Storage and Transportation
1) Before transporting or storing, be sure to remove the tethered power supply air unit and drone battery from the drone and store them separately.
Do not store drone batteries near heat sources or flammable or explosive materials.
2) Keep the storage environment dry and avoid placing drone batteries in locations where they may leak or become damp.
3) If the tethered device is not used for an extended period of time, for storage exceeding three months, the recommended storage temperature is 22°C to 28°C.
Do not store the tethered device or drone battery in locations below -10°C or above 45°C.
4) If the drone battery is not used for more than 10 days, be sure to discharge it to its optimal storage capacity of 40% to 65% before storage. Do not store it in a fully discharged state for extended periods to prevent over-discharge and damage to the battery cells, making it unusable. It is recommended to recharge and discharge the battery every 2-3 months to maintain battery activity. 5) When transporting the tethered power supply box, ensure proper shock absorption. Otherwise, loosening of the internal screws is normal.
2. Maintenance
Inspect and maintain the tethered power supply every 50 takeoffs and landings or 20 hours of flight time to ensure proper operation.
B. Inspect the tethered power supply components for any significant impacts and ensure that all moving parts operate smoothly.
