Mounting Procedure
Step
Mark and cut out the controller hole in the panel according to the dimension information in Figure
1
3-2.
2 Orient the case properly and slide it through the panel hole from the front.
3 Remove the mounting kit from the shipping container and install the kit as follows:
•
For normal installation (NEMA 3/IP55) two mounting clips are required. Insert the prongs
of the clips into the two holes in the top and bottom center of the case
•
For water-protected installation (NEMA 4/IP66) four mounting clips are required. There
are two options of where to install the mounting clips:
1) Insert the prongs of the clips into the two holes on the left and right side of the top and
bottom of the case or
2) on the center on each of the four sides.
•
Tighten screws to 2 lb-inch (22 N•cm) to secure the case against the panel. CAUTION:
Over tightening will cause distortion and the unit may not seal properly.
4 For water-protected installation (NEMA 4/IP66), install four screws with washers into the four
recessed areas in the corners of the front bezel (Figure 3-3). Push the point of the screw through
the center piercing the elastomeric material and then tighten screws to 5 lb-in (56 N•cm).
