Installing the Square 1/8 DIN Panel
Mount Controller
1. Make the panel cutout using the mounting dimen-
sions above.
2. Remove mounting bracket from the back of the
controller.
3. If your controller has a gasket, check to see that
the gasket is not twisted, and is seated within the
case bezel flush with the panel. Place the case in
the cutout. Make sure the gasket is between the
panel cutout and the case bezel.
4. While pressing the front of the case firmly against
the panel, slide the mounting collar over the back
of the control. The tabs on the collar must line up
with the mounting ridges on the case for secure
installation. See Figure 4. Slide the collar firmly
against the back of the panel, getting it as tight
as possible. To ensure a tight seal, use your thumb
to lock the tabs into place while pressing the case
from side to side. Don’t be afraid to apply enough
pressure to install the controller. The tabs on
each side of the collar have teeth that latch into
the ridges. Each tooth is staggered at a different
height, so only one of the tabs on each side are
ever locked into the ridges at a time. Confirm that
the tabs on one side of the collar correspond with
those on the opposite side. Make sure the two cor-
responding tabs are the only ones locked in the
ridges at the same time. If the corresponding tabs
are not supporting the case at the same time, you
will not have a NEMA 4X seal.
5. Insert the control chassis into its case and press
the bezel to seat it. Make sure the inside gasket
