That's pretty standard? Anything that's going straight into 400V (I assume) deserves a good eyeball before it's energised. I doubt their "root of trust" knows how to protect the system from a dead mouse in the bus bars.
I'm not worried about dead mice; I'm worried about tampering. I would have hoped there'd be more guidance than "just look and see if anything looks weird". A determined threat actor can easily side-step that check with, for example, careful desoldering/resoldering technique.
