The electric drive should be placed according to the normal installation state, and waterproof, dustproof and rust-proof measures should be taken.

The electric drive should not be stacked, and other heavy objects should not be placed on the electric drive.

Check the below items every 3 months when not in use for a long time:

1)Rotate the flange/drive shaft by hand to see whether the rotation is smooth, and there is no abnormal noise in the rotation process.

2)Check all screws in the electric drive to see if they are loose.

3)Measure with a 500V megger, the insulation resistance between stator winding and casing should not less than 20 MΩ when cold, or 1 MΩ when hot; The insulation resistance between three-phase power supply cord and shielding layer under cold and hot state should not less than 1 MΩ.
