⑥无人机飞行过程中，不能断开市电的插头或者关闭设备。
⑦接电顺序：连接电源线并接通市电后，再打开紧急断电开关。
⑧使用 此设备 时，无人机系留电池电量不要低于 60%。
⑨无人机起飞之前，开启“紧急断电开关”，否则无人机将无法起飞。
⑩为防止意外发生，禁止在雨雪、霜雾、雷霆、冰雹、沙尘和强风等环境下使用。
⑪为防止意外发生，任何时候都不可徒手触摸TK4线缆（高压800V）。如必须带电接触TK4电缆，请务必带
好绝缘手套（绝缘要求大于800V）。
⑫使用此设备时，在高压塔附近及设备没有接市电时，请务必接上外置接地钉。
⑬为确保设备散热效能，须保持通风口及进风口畅通，避免风道阻塞引发内部热量积累导致
的过热风险。

① Read this manual carefully before use and ensure the TK4 tether cable is properly connected
to the aircraft. To prevent the rotating propellers from striking the tether cable, securely fasten
the hook on the tether cable to the suspension ring on the airborne unit.
② When operating the aircraft, do not continue to increase flight altitude once the 5-meter
remaining cable mark is visible at the ground station. Do not pull or tension the tether cable
manually. Failure to follow this notice may result in cable breakage, equipment crash, personal
injury, or third-party property damage, for which the operator shall bear full responsibility.
③ Please ensure that the AC input voltage from the wall power socket is within the range
of 176‒264 V. This device is recommended to be powered by wall power. If wall power is
unavailable, it is recom- mended to use a matching inverter. This helps prevent equipment
failure caused by unstable or insufficient power supply.
④ When wall power is not available, the device only supports invert- er generators as an
external power source. To avoid overload or underload caused by excessive power
fluctuations during operation, do not use fixed-frequency generators to power the device.
After rigorous testing by our technical department, the following generator model has been
confirmed to be fully compatible with this product, with stable and reliable performance. Recom-
mended Model: Senci SC8000iF inverter generator (see Appendix 1 for details).
The recommended compatible generator models are provided for reference only. The TK4
Tethered Power System assumes no responsibility for the quality, safety, or subsequent firmware
updates of any third-party equipment. In the event of any compatibility issue during use, it is
recommended to contact the corresponding equipment manufacturer first.
⑤ For safety, when using wall power, ensure that the wall power socket is capable of
delivering at least 4500 W output. The voltage and current of the wall power supply must be
stable and reliable.

⑥ During aircraft flight, do not disconnect the wall power plug or power off the device.
⑦ Power connection sequence: First connect the power cable and supply power from the wall
power socket, then turn on the main power switch.
⑧ When using this device, ensure the aircraft tether battery level is not lower than 60%.
⑨ Before takeoff, turn on the "Main Power Switch"; otherwise, the aircraft will not be able to
take off.
⑩ To prevent accidents, do not use the system in rain, snow, frost, fog, thunderstorms, hail,
sandstorms, or strong wind conditions.
⑪ To prevent accidents, never touch the TK4 tether cable (800V high voltage) with bare hands
at any time. If live contact is unavoidable, always wear insulated gloves (with insulation
rating exceeding 800V).
⑫ When using this device near high-voltage towers or when the system is not connected to the
wall power, ensure an external grounding rod is properly installed.
⑬ To ensure proper heat dissipation, keep all ventilation and air intake openings
unobstructed to prevent internal heat accumulation and overheating risks.
⑭ When the TK4 airborne unit been installed to M400, there is one gimbal Skyport it can be
applied at the front.
⑮ ML200 matrix lighting gear (to be fasten on the M400 legs) is not ready for overseas market,
since this would accumulates the TK4 overall power output to 4,000 watts. Without the
lights, TK4 max power rate is 1,500-2,500 watts.
The CZI TK4 Ground Tethered Power System is a high-performance tethering solution designed
for extended drone operations. Utilizing efficient power conversion technology, it converts
AC power into high-voltage DC and transmits it to the airborne unit through the tether cable.
The airborne unit then steps down the high-voltage input into low-voltage power that can be
directly used by the drone’s tethered battery, providing ample and continuous power to both
the propulsion system and mission payloads. The system features a lightweight design, a
high-definition display, and a built-in backup power source, ensuring stable operation even in
harsh environments. With excellent protection performance, the TK4 is ideal for applications
such as emergency lighting and security monitoring, enabling drones to achieve uninterrupted,
around-the-clock flight operations to meet the demands of complex missions.
