Installing the Series F4P Controller
Installing and mounting requires access to the back of
the panel.
Tools required: one #2 Phillips screwdriver.
1. Make the panel cutout using the mounting template
dimensions in this chapter.
2. Insert the controller into the panel cutout. Check
that the rubber gasket lies in its slot at the back of
the bezel. Slide the retention collar over the case,
with open holes facing the back of the case.
3. Align the mounting bracket with the screws tips
pointed toward the panel. Squeezing the bowed sides
of the bracket, push it gently but firmly over the case
until the hooks snap into the slots at the front of the
case.
4. If the installation does not require a NEMA 4X seal,
tighten the four screws with the Phillips screwdriver
just enough to eliminate the spacing between the
rubber gasket and the mounting panel.
For a NEMA 4X seal, tighten the four screws until
the gap between the bezel and panel surface is .020
inch maximum. (See figure 3c). 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 overtighten. Overtightening could damage the
the mounting bracket.
