• Daily Inspection: Performed by the electrician on duty, focusing on visual checks, listening for abnormal sounds, comparing temperatures by touch, and observing instrument readings.
• Periodic Maintenance: Performed monthly or quarterly by designated personnel; after a power outage, thoroughly clean the casing and cooling fins using dry compressed air or a soft-bristled brush (washing with water is strictly prohibited), and check the tightness of all bolts and grounding connections.
