components inside the mainframe and controller. Always
disconnect AC power to the mainframe when servicing.
To install a plug-in controller into a mainframe, release the
locking device on the lower edge of the unit by pulling the
plunger gently away from the panel. Align the upper and lower

mainframe card guide slot and slide in until the rear connector
is completely engaged. Lock the controller into the frame by
depressing the plunger on the locking device.
