Watlow EZ-ZONE ® RUI/Gateway • 5 • Chapter 2 Install and Wire
Mounting the Remote User Interface (RUI)
1. Make the panel cutout using the mounting template di-
mensions 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 RUI. If
the installation does not require an IP66/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 an IP66/NEMA 4X seal, place the blade of a screw-
driver in the notch of the mounting collar assembly an
push to ward the panel while applying pressure to the
face of the RUI. Don't be afraid to apply enough pressure
to properly install the RUI. If you can move the case as-
sembly back and forth in the cutout, you do not have a
proper seal. The tabs on each side of the bracket have
teeth that latch into the ridges. Each tooth is staggered
at a different depth from the front so that only one of
the tabs one each side is locked onto the ridges at a time.
The seal is good if the distance from the panel and the
top half of the assembly is 16 mm (0.630 in.) or less, and
the distance bottom half and the panel is 13.3 mm (0.525
in.) or less
