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.

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 2-3). Push the point of
the screw through the center piercing the elastomeric material and then tighten screws
to 5 lb-in (56 N•cm).
