Unfortunately, I had to request a refund for a defective drive purchase. Initially, the inverter was replaced in the warranty and then returned definitively, once the equipment returned to present the same defect. It took more than 30 days from the cancellation of the purchase to the refund of the amount. Anyway, the problem has been solved. I intend to do business with the company again, despite the problem.
