Procedure steps
1 Unlock the door by turning the key to the left as shown in the figure “A
lockable vented door NTRU0423, outside view” (page 676) and open it as
the arrows indicate.
2 Using the figure “A lockable vented door NTRU0423, inside view”
(page 675), locate the door-to-frame ground cable.
3 Disconnect the ground cable by prying its end off of the spade on the door.
Avoid bending the spade or the neck of the cable connector.
4 Using the figure “A lockable vented door NTRU0423, inside view”
(page 675), locate the return spring on the upper hinge pin.
5 While still holding the door, compress the door pin spring downwards until
the tip of the pin passes the edge of the door.
6 Tilt the top of the door away from the frame until the hinge pin clears the
hole.
7 Release the hinge pin.
8 Raise the door off the lower hinge pin.
9 Lie the door on a side temporarily out of your way where it will not be a
safety hazard. The rounded edge of the door means it can more easily
slide to the floor.
