The controller label matches our order, but the setup guide's panel layout doesn't match what arrived. I have kept the package unpowered. What identification should support use to find the applicable instructions?
Send the arm, controller and cable identifiers with clear panel photographs and the guide's revision; ask for applicable documentation and confirmation that the supplied combination belongs together, not a guessed connection from similar shapes
Identification bundle sent, including the cable suffix. Installer and purchasing compared their copies and have the same wrong guide. Seller has named a technician but no applicable document yet; equipment remains unpowered.
