Open vs Closed VFDs

A VFD’s enclosure must suit the environment and installation specified by its manufacturer. Grinding dust, conductive debris and moisture make enclosure selection important.

Open drives

An open drive may require a separate correctly designed enclosure and installation. Do not treat an exposed drive as a ready-to-use standalone workshop controller.

Enclosed drives

Diktator’s motor/VFD packages use enclosed drives. Check the exact model’s enclosure rating, mounting instructions, ventilation/clearance requirements and permitted environmental conditions. An enclosure rating is not permission to expose equipment to any water, coolant or dust condition.

Keep the package within its manufacturer’s operating conditions. Electrical installation and changes should be handled by a qualified electrician. For identification, send the VFD label to support@diktatorgrinder.com.
