PMI Controller • 24 • Chapter 2 Install and Wire
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 rmly against the
panel, slide the mounting collar over the back of
the controller. If the installation does not require
a NEMA 4X seal, simply slide together until the
gasket is compressed.
3. For a NEMA 4X (UL50, IP65) seal, alternately place
and push the blade of a screwdriver against each
of the the four corners of the mounting collar
assembly. Apply pressure to the face of the con-
troller while pushing with the screwdriver. 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. 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.
Slide the mounting collar over
the back of the controller.
Place the blade of a screwdriver in
any of the corner of the mounting
collar assembly.
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.
