locking device on the lower edge of the unit by pulling the plunger

gently away from the panel. Align the upper and lower edges of

the printed circuit board on the controller with the mainframe

card guide slot and slide in until the rear connector is completely

engaged. Lock the controller into the frame by depressing the
