Operating Requirements 

  Transport, use, and store the device in allowed humidity and temperature ranges. 

  Avoid liquids splashing on the device. Do not place objects full of liquid on the device to avoid 

liquid flowing into the device. 

  Do not disassemble the device without professional instruction. 

  Use the device at rated input and output voltage. 

  Make sure that the power supply of the device works properly before use. 

  Do not pull out the power cable of the device while it is powered on. 

  When removing the cable, power off the device first to avoid personal injury. 

  Operating temperature range: –30 °C (-22 °F) to +65 °C (+149 °F). 

  This is a class A product. In a domestic environment this may cause radio interference in which 

case the user may be required to take adequate measures. 

Installation Requirements 

  Observe all safety procedures and wear required protective equipment provided for your use 

while working at height. 

  Use the battery properly to avoid fire, explosions, and other dangers. 

  Do not expose the device directly to sunlight, and keep it away from heat. 

  Do not install the device in a damp environment, and keep it away from dust and soot. 

  Install the device in a well-ventilated environment. Do not block the vent of the device. 

  Strictly abide by local electrical safety standards, and make sure that the voltage in the area is 

steady and conforms to power requirements of the device. 

  Use the power adapter or case power supply provided by the device manufacturer. 

  Connect the device with the adapter before power on. 

  Do not connect the device to more than one power supply. Otherwise, the device might be 

damaged. 

  The device is a class I electrical appliance. Make sure that the power supply of the device is 

connected to a power socket with protective earthing. 

  Be sure to ground the device (cross section of copper wire: > 2.5 mm²; resistance to ground: ≤ 4 

Ω). 

  Voltage stabilizers and lightning protection devices are optional according to the power supply 

and surrounding environment. 

  To ensure heat dissipation, the gap between the device and the surrounding area should not be 

less than 10 cm on the sides and 10 cm on top of the device. 

  When installing the device, make sure that the power plug and appliance coupler can be easily 

reached to cut off power. 

  Do not block the ventilator of the device with objects, such as newspaper, table cloth or curtains. 

  Do not put open flames, such as a lit candle, on the device.
