3. Mounting the MAP450D

3.1. Panel Mount

The OIT is installed in a panel by separating the front and rear covers of the OIT, and then sandwiching the panel between the two. The gasketed surface of the OIT’s front cover provides the environmental seal to NEMA 4 and NEMA 12 standards. The rear cover helps shield the OIT from dust, dirt, induced electrical noise, and physical damage.

The OIT is mounted using four #6-32UNC screws sandwiching the OIT halves to panel. Screw length is equal to panel thickness plus 1/2 inch.

NOTE: The mounting screws must not be torqued to more than 18 pound-inches. Over-torquing can strip the threads in the front half.

Figure 9 shows the dimensions of the panel cutout required for proper panel installation. The panel cutout should be cleaned and deburred before the OIT is installed.
