Wiring Guide
For the sake of reusability we have wired our VFD into a semi-permanent control panel using DIN terminal blocks to connect the user wiring. This control panel is designed to be fully enclosed in scenery during use.
Be sure to follow the VFD manufacturer's specifications when selecing wiring materials. You don't want to under-spec the mains or motor wiring.
