There is much more to consider. It's very difficult to say from that picture alone because actually it's quite lacking in context... by that, is it taken from the side of the unit, the top looking down? Do any of the surfaces get hot? The cables disappear into the void at the top of the picture... what's in that void? Where does the twin and earth go? If that T+E originally supplied a socket mounted on a wall (and now that socket is no longer there), there is effectively no longer any marker for the 'safe zone' in which the cable may have been running.
