Panel 3A 48/24VDC with doors that do not latch Panel 3A 48/24VDC was found partially latched. Only one of three latches were engaged (the door was out of plane with the rest of the item).
Communication from the shift manager informed Engineering that Operations personnel had secured the latches on 7/30/2012 at approximately 17:55 hours.
Therefore, door is not a seismic concern.
