The UR5e delivery has a crushed crate corner and a shifted internal support beside visible pendant-enclosure damage. I have kept it unpowered and retained the packaging. The seller says to switch it on; I want an assessment that considers how the load moved first.
Keep it unpowered. Send the unit identifiers and photographs showing the damage and displaced supports, and ask the seller to arrange a competent assessment. A successful power-on would not establish that the delivery damage is limited to the visible enclosure.
