Tips: Variable frequency drive storage notifications
If the VFD is not used for long periods of time, it may be damaged, which is caused by the environmental conditions that do not meet the storage conditions of the VFD. Therefore, the VFD should be placed in the packing case when stored, and note the following:

It is the best to store in absence of sun, no dust and dry place.
The ambient temperature is best in the range of -20~40℃.
The relative humidity is best in the range of 20% to 90%, without condensation.
Avoid long-term storage in corrosive gases and liquids environment.
Long term storage (2-3 years) will lead to electrolytic capacitor degradation. Adding voltage can self-repair certain degree of deterioration. In long-term storage, it should be regularly (within 6 months) powered on for at least 5 hours, and the input voltage should be gradually raised to the rated value by voltage regulator. If the storage period is more than 10 years, the electrolytic capacitors rubber sealed will lose efficacy and must be replaced.

Motor high shaft voltage

Question is for high shaft voltage. Does bearing insulation at one side is enough to protect both bearings of motor? Why shaft grounding is required?

ATO Responded

Best practice is to have a good earthing system for high frequencies, then insulate both bearings and then earth DE bearing to keep shaft voltage close to ground potential. For VFD drives it is essential to have correct earthing otherwise insulated bearings and brushes will not help.

Motor shaft voltage

In my option, it depends on the horsepower of the motor. The costs of motor under 60 hp doesn't not justify insulating either bearing. 75 hp (360 frames) to the end of t frames roughly 250 hp in a 4 pole, i would just insulating one bearing. Everything after t frames I would insulate both bearing if being used on a VFD. After 2000 hp I would insulate and add a shaft grounding ring for insurance. The level of protection must be weighted against how critical the motor is, and the costs of the protection versus the costs of replacement/time to reorder.
