How do I ensure the VFD is shipped safely to my location?

Use a reputable transport service that specializes in electronic equipment. Ensure the VFD is securely packaged to prevent damage during transit and consider insuring the shipment.

What is the maintenance schedule for a variable-frequency drive?

Regularly inspect for dust and debris, check connections for tightness, and ensure proper ventilation. Follow the manufacturer's recommendations for periodic checks and servicing.
