Before powering on, inspect the device for any damage during transit, such as loose screws, physical abnormalities, shaken-off terminal wires, or moisture issues. Address any issues before proceeding.

For safety, add an external air switch at the power input terminal to control input power. Connect the ground wire and input power wires properly according to the rear panel labels. Confirm the input supply voltage matches the specifications in this manual.

The cooling fan is temperature-controlled and will start automatically when internal temperatures exceed the threshold. Fan speed dynamically adjusts with output load. Do not block the air inlets and outlets.

When the internal temperature reaches the overheating threshold, the machine stops working for protection. It will auto-resume normal operation once the internal temperature drops.

Avoid placing the device in environments with severe vibration, humidity, direct sunlight, rain, or high concentration of corrosive gases and dust particles.

Regular dust removal (using dry compressed air) can significantly increase device service life. Do not open the external casing without professional guidance, due to high internal voltages.

If the device is idle for more than 6 months, store it in a dry, ventilated room and power it on for at least 30 minutes to maintain component longevity.

Warning: Only connect to your load equipment after performing a normal power-on test without errors.

If any abnormal operation occurs, switch off the input power immediately. Verify all wiring, screws, switches, and settings. If issues persist, please notify support promptly to resolve the problem. Do not perform unauthorized disassembly.
