3.1. Panel Mount

TheOIT is installed in a panel by separating the front and rear covers of the OIT,
andthen sandwiching the panel between the two. Thegasketed surface of the OIT’s
frontcover 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
physicaldamage.
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.
