FIG. 1 PANEL HOLE DIMENSIONS

Step 3. Use a phillips head screwdriver and install the five (5) 6-32 x

1/2 inch screws that fasten the bezel to the panel. (See Fig. 3) Use a torque screw driver and torque each screw to 10 inch/ pounds. DO NOT OVERTIGHTEN!

Step 4. Thread the four (4) threaded rods through the appropriate

holes in the panel and into the bezel. For the retrofit you don’t have to place the rods through the holes. (See Fig. 4)

Step 5. Hand tighten each rod until you can no longer turn the rod. Do

not force the rods or use pliers of any kind.

Step 6. Put the Display cable and connector through the 1.25-inch

hole in the panel door or cover and plug the display connector into the display header in the bezel. (See Fig. 3)

Step 7. Gently slide the electronic enclosure onto the threaded rods

while making sure the display cable glides easily into the enclosure and does not kink. Move the electronic enclosure toward the panel until it stops. (See Fig. 3)

Step 8. Thread the four (4) 6-32 thumb screws onto the threaded rods

until tight. Do not use pliers on the thumb screws.
