Before powering on, inspect the device for transportation damage, loose screws, abnormal appearance, disconnected wires/terminals, or signs of dampness. Address any visible issues before operation.

The local power switch control operates the internal auxiliary power. For safety, install an air switch at the power input terminal. Ensure correct connection of the ground wire and input phase wires based on the rear panel designations.

The cooling fan is temperature-controlled. It starts when internal heat reaches the activation point. Fan speed changes depending on output load levels. Do not block the air inlet or outlet vents during operation.

If the internal temperature exceeds the high safety threshold, the system triggers an automatic shutdown to prevent damage. It resumes operation automatically after cooling down.

Ensure the ambient air is free from excessive dust, acid, corrosive elements, or aggressive dampness. Avoid installing in areas prone to high vibration, heavy impact, rain, or direct sunlight exposure.

Perform regular dust removal (dry compressed air is recommended) to enhance the lifespan and reliability of the hardware. Do not open the metal chassis enclosure due to the hazard of internal high voltage.

Store in a dry, ventilated room during long idle periods. If storage exceeds 6 months, power on the device and let it run idle for at least half an hour.

Warning: Only connect your electrical loads to the power terminals after confirming a successful, error-free system self-test.

Troubleshooting: If operational issues occur, immediately switch off the power. Check the external wiring and control knob settings. For internal issues, do not attempt self-repair to prevent electric shocks. Contact professional technical support.
