Product Instructions

  • 1 Before powering on, inspect the device for transport damage. Check if screws are loose, the appearance is normal, power cords or terminals are secure, and ensure the unit is not damp. Address any issues before operation.
  • 2 The local power switch controls the internal auxiliary power supply. For safety, install an external air switch at the power input terminal. Connect ground and input wires correctly according to the back panel label. Verify that the input voltage matches the manual specifications.
  • 3 The cooling fan is temperature-controlled and starts when the internal temperature reaches the preset threshold. Fan speed varies based on output voltage and current. Keep the air inlets and outlets clear during operation.
  • 4 If the internal temperature exceeds the overheat protection threshold, the system automatically shuts down. It will resume operation automatically once it cools down.
  • 5 Operate the equipment in environments free from excessive dust, acid, corrosive gases, severe vibrations, impact, rain, and direct sunlight.
  • 6 Regularly clean dust using dry compressed air to extend the service life and reliability. Do not open the outer casing, and avoid damaging internal components.
  • 7 Store the unit in a dry, ventilated room during long idle periods. If stored for over 6 months, power on the device and run it for at least half an hour before use.
  • 8 Warning: Only connect load equipment after verifying that the power-on test is normal and error-free.
  • 9 Malfunction Handling: If the unit operates abnormally, turn off the power switch immediately. Verify all internal and external connections, check screws, and ensure all switches and knobs are positioned correctly. High voltage is present inside; do not attempt unauthorized disassembly or repairs. Contact technical support for assistance.
