Installing the 1/8 DIN Series SD Controller
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 1/8 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 until
they disengage from the retention collar.
2. Squeeze the release tabs on the long sides of the mounting bracket and
slide the mounting bracket off the back of the controller. Remove the reten-
tion collar and push the controller out of the panel cutout. Be ready to sup-
port the controller as it comes through the front panel.
Installing and mounting
requires access to the
back of the panel.
Tools required:

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.
