•
Install the four (4) 6-32 pan head machine screws into the
threaded slots at each corner of the controller.
•
Hold the controller so that it is aligned and flush against the
enclosure front panel throughout the entire tightening pro-
cess.
•
Facing the rear panel of the controller, tighten each screw in
a clockwise direction from corner to corner until each screw
is finger tight.
•
Using a phillips screw driver, continue the clockwise direc-
tion and partially tighten each screw until the NEMA 4
bezel gasket is completely compressed and the bezel is flush
against the front panel of the enclosure. Do not tighten one
screw down completely and then go on to the next screw.
Each screw must be tightened a little before going on to the
next to maintain the alignment between the controller and
the front panel of the enclosure.
CAUTION
DO NOT OVER TIGHTEN THE MACHINE SCREWS. OVER TIGHTENING
CAN DEFLECT THE BEZEL SO THAT IT WILL NOT BE WATER TIGHT
AND/OR BREAK OFF THE CORNERS OF THE BEZEL.

Step 1.
Ensure that all Electrostatic Discharge (ESD) precautions
have been taken before installation.

The controller comes with a NEMA 4-rated compression gas-
ket. Make sure this gasket is properly seated in the bezel
before installation.
Step 3.
The front panel comes with two mounting brackets mounted
on the bezel. Remove the nuts that fasten the brackets to the
bezel, and remove the brackets.
Step 4.
Gently slide the front panel into the enclosure cutout until the
gasket is seated against the front of the enclosure. (See Fig. 3-

The nuts on the mounting studs barely clear the cutout. It might take a little adjusting
to get the bezel into the cutout.
Step 5.
Place the brackets, #6 flat washer, lock washer and hex nut on
the four bezel studs.
Step 6.
Make sure that the bezel is centered in the cutout.
