See the 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 equipment.
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.
Removing the Series 96 Controller
1. Hold the controller with one hand while using the other hand to loosen the screws with
a #2 Phillips screwdriver until the end of the screw is flush or past the end of the can-
tilevers; see the figure below.
2. After the screws have been loosened, hold the controller with one hand while squeezing
the two screws together with the other hand. Then simply slide the mounting collar off
the controller.
