Watlow Series SD ■ 7 ■ Chapter 2 Install and Wire
Installing the 1/16 DIN Series SD Controller
1. Make the panel cutout using the mounting template dimensions in this chap-
ter.
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 controller,
with the locating holes on the top and bottom, 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 retention col-
lar. 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 two
screws with the Phillips screwdriver just enough to eliminate the spacing be-
tween the rubber gasket and the panel.
For an IP65/NEMA 4X seal, tighten the two screws until the gap between the
bezel and panel surface is 0.6 mm (0.024 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 damage the
mounting bracket.
Removing the 1/16 DIN Series SD Controller
1. Remove all the wiring connectors from the back of the controller. While sup-
porting the controller with one hand, use the Phillips screwdriver to unscrew
the two screws on the mounting bracket until the tips are flush or past the
end of the hooks.
2. Squeeze the two screws together on the mounting bracket to release the hooks
from the slots and slide it off the controller. Remove the retention collar and
push the controller out of the panel cutout. Be ready to support the controller
as it comes through the front panel.

Caution: Follow the installa-
tion procedure exactly to
guarantee a proper IP65/NE-
MA 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 damage to
equipment.
Note: Be careful not to over-
tighten the screws. This may
cause the mounting 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.
