Before powering on, check the stored and transported switch power supply. Inspect for any damage during transportation, such as loose screws, abnormal appearance, shaken power cords or terminals, and dampness. Handle issues in a timely manner.

The local power switch controls the internal auxiliary power supply. For safety, install an air switch at the power input terminal. Connect the ground wire and input power wire according to the rear panel labels. Confirm the input power voltage matches manual recommendations.

The cooling fan is temperature-controlled and starts when internal temperatures cross the starting threshold. Speed varies based on load conditions. Maintain clear, unblocked inlet and outlet paths for proper airflow.

If internal temperatures reach the overheating threshold, the machine stops automatically to prevent damage. It resumes operation automatically once the temperature drops slightly.

When operating the equipment, ensure airborne dust, acid, or corrosive gases stay within normal limits. Avoid severe vibration, sudden impacts, exposure to rain, and direct sunlight.

Regular dust removal extends service life and improves reliability. Use dry compressed air to clear out dust. Do not open the casing unauthorized, as high voltage is present inside.

When stored idle for extended periods, place the machine in a dry, ventilated room. If stored for over 6 months, power on the device and let it run for at least half an hour.

Warning: Only connect power-consuming load devices to the power supply after verifying a normal and error-free power-on test.

For malfunctions, turn off the switch immediately. Inspect external and internal connections for looseness and ensure switches are in correct positions. If issues persist, avoid unscrewing the casing without proper qualification due to high-voltage hazards. Contact technical support immediately.
