About safety precautions

Warning – Serious injury or death is possible if all warnings are not followed.

  • Electrical shocks can occur if the unit is disassembled, improperly repaired, or modified, voiding the warranty.
  • Please do not touch products without a cover, as the exposed high-voltage parts may cause an electric shock.
  • Do not exceed the specified ambient temperature. Failure to do so may result in fire or an electric shock.
  • Do not insert or remove the power plug with wet hands. It may cause an electric shock.
  • Do not bend or pull the power cord or AC plug by force, and do not scratch it. Failure to do so may result in fire or an electric shock.

Caution

Follow these precautions to prevent personal injury or physical damage to the device.

  • Only use the correct input voltage, frequency, output voltage, and current. Failure to do so may result in fire or electric shock.
  • Do not use in environments with moisture, oil, smoke, dusty places, or corrosive gases. Failure to do so may result in fire or electric shock.
  • If no output is detected or other abnormalities are recognized during use, please stop using it immediately and contact our sales office. If the product is an AC adapter, unplug the power plug.
  • Do not cover or wrap the AC adapter or charger with clothes, bedding, etc. It will hinder heat dissipation and may cause overheating or fire.
  • When unplugging the AC adapter, carefully remove the body or plug from the outlet. Forcefully pulling the cord may damage it and cause a fire.
  • When unplugging the AC adapter, permanently gently remove it by holding the AC adapter body or the AC plug from the outlet. Pulling on the cord can damage it and may lead to a fire hazard.
  • Please insert the AC adapter firmly and firmly in.

If you have any questions, please do not hesitate to contact our UNIFIVE sales representatives or your dealer.
