Before powering on, check the stored and transported switch power supply. Inspect for any transport damage, such as loose screws, abnormal appearance, loose power cords/terminals, or moisture issues.

The local power switch controls the auxiliary power supply inside. For safety, install an external air switch at the input terminal to control overall power input. Wire according to the rear panel labels and confirm the input voltage matches the manual specification.

The cooling fan is temperature-controlled and automatically starts when internal temperatures rise. Fan speed varies with voltage/current load. Always keep the fan inlets and outlets clear during operation.

If internal temperatures exceed the overheating threshold, the machine will shut down automatically to prevent damage. It will resume operation automatically once the temperature drops.

Operate the equipment in environments without excess dust, acids, corrosive gases, severe vibrations, rain, or direct sunlight.

Perform regular dust removal using dry compressed air to extend service life and reliability. Never open the casing without authorization due to internal high voltage hazard.

Store in a dry, ventilated room when idle. If stored for over 6 months, power on and run the device for at least 30 minutes to maintain component health.

Warning: Do not connect to load equipment until the power-on testing is completely finished and confirmed normal.

Troubleshooting: If abnormal operation occurs, power down immediately, check all wiring, terminal screws, and knob settings. Do not disassemble the casing yourself. For unresolved problems, contact technical support.
