[WH40K] Can an ordinary human use Space Marine Armor?

Outside of heresies in using them. Can salvaged SM Power Armor be used by an ordinary human? If not in a moments notice, can he/she modify it to work?

No, but there are variants of power armor specifically designed for normal humans.  Space Marine power armor is designed to interface directly with his body in such a way that it becomes a natural extension of his own self.  They can move and interact with other objects as if they were using their own flesh.

Examples of normal humans who use power armor include the Sisters of Battle, an all female military order who are not space marines, but are confidant and powerful warriors for the Emperor.
