The tabs on each side of the mounting collar have teeth that latch into the ridges on the sides of the controller. Each tooth is staggered at a different depth from the front so that only one of the tabs, on each side, is locked onto the ridges at a time.
Note: There is a graduated measurement difference between the upper and lower half of the display to the panel. In order to meet the seal requirements mentioned above, ensure that the distance from the front of the top half of the display to the panel is 16 mm (0.630 in.) or less, and the distance from the front of the bottom half and the panel is 13.3 mm (0.525 in.) or less.
Removing the Mounted Controller from Its Case
1.From the controller's face, pull out the tab on each side until you hear it click.
1.Make the panel cutout using the mounting tem- plate dimensions in this chapter.
Insert the case assembly into the panel cutout.
2.While pressing the case assembly firmly against the panel, slide the mounting collar over the back of the controller.
If the installation does not require a NEMA 4X seal, slide the mounting collar up to the back of the panel tight enough to eliminate the spacing between the gasket and the panel.

3.For a NEMA 4X (UL50, IP66) seal, place the blade of a screwdriver in the notch of the mount- ing collar assembly and push toward the panel while applying pressure to the face of the control- ler. Don't be afraid to apply enough pressure to properly install the controller. The seal system is compressed more by mating the mounting collar tighter to the front panel (see pictures above). If you can move the case assembly back and forth in the cutout, you do not have a proper seal.

2.Once the sides are released, grab the unit above and below the face with two hands and pull the unit out.
If it is difficult to pull the unit out, remove the connectors from the back of the controller. This should make it easier to remove.
