Wiring inspection: Regularly check whether the power and control line connectors are loose or oxidized, and promptly tighten or replace the wiring terminals if any problems are found; Check whether the contacts of the contactor and relay are burned. If there are burn marks, they need to be polished or replaced to avoid poor contact. Grounding protection: Ensure that the equipment grounding device is intact, the grounding resistance is ≤ 4 Ω, and the grounding wire is not broken or loose; Regularly test the grounding continuity to avoid electric shock accidents caused by leakage. Motor maintenance: Cleaning: Clean the dust on the motor casing every 100 hours to ensure proper heat dissipation; Bearing lubrication: Add lubricating grease (lithium based grease) to the motor bearings every 2000 hours; Insulation test: Test the insulation resistance of the motor every year. If the resistance value is ≥ 1M Ω, it is qualified. If it is lower than the standard, maintenance is required.
