Can animated artifact equipment equip itself?

Can animated artifact equipment equip itself?

No, it can't equip to anything (and if it was, it isn't any more):


301.5c An Equipment that's also a creature can't equip a creature. An Equipment that loses the subtype "Equipment" can't equip a creature. An Equipment can't equip itself. An Equipment that equips an illegal or nonexistent permanent becomes unattached from that permanent but remains on the battlefield. (This is a state-based action. See rule 704.) An Equipment can't equip more than one creature. If a spell or ability would cause an Equipment to equip more than one creature, the Equipment's controller chooses which creature it equips.

301.5c An Equipment that's also a creature can't equip a creature.

So, if Xenic Poltergeist animates an attached equipment, it becomes immediately unattached, true?

Yes, that is correct. It was a very real strategy in Vintage from a long time ago, using Karn, Silver Golem to invalidate Equipment.
