Crushed crate and shifted supports. Damage near the FR5 controller enclosure. Kept arrival photos and packing; seller says switch on, with no assessment method.
Keep it unpowered and ask for an assessment by a competent person with a procedure appropriate to that damage; a seller asking whether it starts has not established that energising it is an appropriate inspection step.
I would preserve the receiving condition in one indexed set. Crate, supports, equipment identity, affected area. It saves the next person deciding that five separate photographs describe five separate deliveries, which is apparently a popular administrative sport.
Jack's distinction is worth keeping in the correspondence, Kai, because a referral to technical support is not their assessment and should not silently become a release to use the equipment.
Are they specifying how it should be protected for that return, given the original supports shifted? Reusing the damaged packing by default could create a fresh argument about when another mark appeared.
