Watlow EZ-ZONE™ RUI/Gateway • 4 • Chapter 2 Install and Wire
Mounting the Remote User Interface (RUI)
1. Make the panel cutout using the mounting template
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
RUI.
If the installation does not require an IP66/NEMA 4X
seal, slide the mounting collar up to the back of the pan-
el tight enough to eliminate the spacing between the gas
ket 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 and
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
assembly 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
