Send the full pendant-assembly label and external connection photographs with the exact guide revision. Ask their technical contact to identify the applicable installation documents. Matching the arm label alone won't settle a different pendant assembly.
Ask them to return the document set against that identifier, not just another general manual link. Your installer should be able to keep the answer with the actual supplied assembly.
Victor, agreed. And include the controller connection arrangement in that confirmation, so the corrected pendant page doesn't leave the other end to guesswork.
Keep that exact document set with the equipment record. A later generic download should not replace the instructions that actually match this assembly.
