Mount the VFD securely about the panel, ensuring that it is effectively grounded and that every one connections are restricted. Follow the maker’s Directions for set up and make any needed changes to support the VFD.
This variation presents a considerable energy reduction compared to fastened-speed Procedure for a comparatively modest reduction in speed. For example, at 63% speed a motor load consumes only 25% of its comprehensive-speed energy. This reduction is in accordance with affinity regulations that outline the relationship concerning numerous centrifugal load variables.
Use devoted grounding conductors and join them towards the selected grounding factors. This can assist to dissipate any opportunity electrical faults and shield both of those the products and personnel.
