Installing the Series 97 Controller
Installing and mounting requires access to the back of the panel.
1.
Make the panel cutout using the tear-out mounting template found on the previous
page, or the dimensions found in this chapter.
2.
Check to see that the gasket is properly seated into the gasket channel on the front
bezel and that it is not twisted. Make sure that the rounded surface of the gasket is the
surface that is exposed from the gasket channel, as this is the surface that will mate to
the panel surface. Insert the controller into the panel cutout.
3.
With the controller inserted into the panel cutout, take the retention collar and slide it
over the controller, making certain that the two locating holes in the retention collar are
visible from the rear of the controller, with one hole pointing up and one pointing down.
Then, take the mounting collar and slide it over the controller, making certain that one
cantilever is pointing up and one is pointing down also. With one hand holding the con-
troller and the other hand using a #2 Phillips screw driver, tighten the two screws in
the mounting collar until the gap between the bezel and panel surface is .025” maxi-
mum. See figure below. Make sure that you cannot move the controller back and forth
in the cutout. If you can, you do not have a proper seal.

CAUTION: Follow the installation procedure exactly to guarantee a proper NEMA 4X seal. Make sure the gasket between
the panel and the rim of the case is not twisted and is seated properly. Failure to do so could result in damage to equip-
ment.
NOTE: Be careful not to over-tighten the screws. This may cause the mounting cover to fail. Over-tightening occurs when
the front bezel is touching the customer’s front panel.
