Chapter 2 - Installation of Computer
The panel mount versions of the ePC-Plus units are intended to be mounted in and used where
NEMA 1, NEMA 4/4x and NEMA 12 type enclosures are employed. Enclosures made of heavier gauge
metal work better because they won’t deform or bend as easily when the monitor’s sealing gasket is
compressed. The monitor meets NEMA 4/12 sealing specifications when properly installed in an
approved NEMA enclosure constructed from 14-gauge or heavier steel. The computer uses “U”-shaped
clips and a special gasket to achieve the proper seal.
When selecting an enclosure remember to allow adequate space around the rear of the computer
for good air flow. Do not block air flow from below or above the monitor. If possible mount the computer in
a vertical orientation. The unit is designed to work in environments up to 50 degrees Centigrade ambient
temperature inside the enclosure. Remember to account for heat dissipated from other equipment that
may be installed inside the same enclosure.
To install the computer, make a cutout according to the diagrams below in one of the walls of
your NEMA enclosure. Next hold the unit in place while you install the mounting clips. Tighten the clips
to the point were the back of the unit’s front bezel just begins to contact the front of the NEMA enclosure.
The use of an adjustable torque driver is recommended. The screws should be tightened to 8 inch-
pounds. Tighten the clips in a cross pattern. This will help to develop an even pressure on the sealing
gasket. DO NOT OVER TIGHTEN AS DAMAGE CAN RESULT IN THE COMPUTER CAUSING LOSS
OF SEALING INTEGRITY.
