Caution: Follow the instal-
lation procedure exactly to
guarantee a proper IP65/
NEMA 4X seal. Make sure
the gasket between the
panel and the rim of the
case is not twisted and is
seated properly. Failure to
do so could result in dam-
age to equipment.
Note: Be careful not to
over-tighten the screws.
This may cause the mount-
ing bracket to fail. If the
front bezel is touching the
front panel, the mounting
bracket is too tight.
Installing and mounting
requires access to the
back of the panel.
Tools required:
one #2 Phillips screwdriver.
Tools required:
• one #2 Phillips screwdriver
• one flat-head screwdriver

Installing the 1/4 DIN Series SD Controller
Arrows indicate the
direction of pull to
remove the
connectors.
1. Make the panel cutout using the mounting template dimensions in this
chapter.
2. Check that the rubber gasket lies in its slot at the back of the bezel. Insert
the controller into the panel cutout. Slide the retention collar over the con-
troller, with the locating holes facing the back of the controller.
3. Slide the mounting bracket over the back of the controller with the screw
tips pointed toward the panel, aligning with the locating holes in the reten-
tion collar. Push it gently but firmly over the controller until the hooks snap
into the slots at the front.
4. If the installation does not require an IP65/NEMA 4X seal, tighten the four
screws with the Phillips screwdriver just enough to eliminate the spacing
between the rubber gasket and the panel.
For an IP65/NEMA 4X seal, tighten the four screws until the gap between
the bezel and panel surface is 0.5 mm (0.020 in) maximum. Make sure that
you cannot move the controller back and forth in the cutout. If you can, you
do not have a proper seal. Do not over-tighten. Over-tightening could dam-
age the mounting bracket.
Removing the 1/4 DIN Series SD Controller
1. Remove all the wiring connectors from the back of the controller. Using the
Phillips screwdriver, unscrew the four screws on the mounting bracket (two on
top, two on bottom) until they disengage from the retention collar.
2. Slide the tip of a flat screwdriver between the controller and the center top
side of the mounting bracket. Rotate the screwdriver 90 degrees, stretching
the bracket away from the controller so the hooks on the bracket disengage
from the slots. Hold the bracket and press the controller forward slightly to
prevent the disengaged hooks from snapping back into the slots.
3. Repeat this operation to disengage the hooks on the bottom side of the mount-
ing bracket.
4. Press with one or two fingers on the lower half of the back of the unit so that
the controller slides forward toward the panel. Hold the bracket steady; do
not pull back. Be ready to support the controller as it comes through the front
panel.
