nPC200 Unit Installation
The nPC200 is intended to be mounted on the flat surface on the inside of a NEMA Type 1, 4/4x
or NEMA 12 enclosure. See the specifications section for the dimensions and mounting dimensions
required for mounting this unit.
When selecting an enclosure remember to allow adequate space around the computer for good
air flow. Do not block air flow around the unit except for the mounting surface. The computer can be
mounted on a horizontally or vertically to a wall or shelf within the enclosure. 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.
Rack Mount Unit Installation
The ePC1950 with a rack mount front panel is intended to be mounted to a 19.0” wide rack in a
NEMA Type 1 or better enclosure. The unit can be mounted using standard rack mount hardware (not
supplied) via the eight (4 each side) counter-bored holes in the front of the panel. The front panel is
intended to be mounted in a vertical height of 9 U (16.0”) on the rack. This unit is not NEMA sealed when
mounted like the panel mount versions.
When selecting an enclosure remember to allow adequate space around the rear side of the
computer for good air flow. 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.
Enclosed Unit Installation
The enclosed ePC-Plus products are intended to be stand-alone NEMA Type 1 units. These are
required to be mounted to a VESA style mount with a minimum load rating of 40 pounds. A desktop
stand, wall mount, or articulating arms are examples of VESA style mounts that can be utilized. These
units are vented for air flow and are not dust or water proof. Care should be taken to not utilize these
units in areas where high concentration of particulate matter or moisture are present. If these conditions
do exist then the use of the panel mount versions in an appropriate NEMA 4, 4x, or 12 enclosure should
be considered. The warranty may be voided if high levels of moisture or particulate matter are
determined to be the cause of a failure. The ePC-Plus –EN units have filters on the rear to filter incoming
air. These filters should be carefully removed and cleaned periodically depending on service conditions.
In some applications this may need to be checked and cleaned often.
These units are designed to work in environments up to 50 degrees Centigrade ambient
temperature around the enclosure. Impeding the airflow around this unit or clogged filters will severely
affect the reliability of the unit by raising the internal temperature. Assure that there is adequate airflow
around the unit.
NEMA Type 1 is not sealed against water and/or dust; it is simply provides protection from
operators shocking themselves. It also offers a certain amount of fire containment it the event of a
catastrophic failure inside the unit. As stated previously NEMA 1 is not waterproof or dust proof and is
not intended to be utilized in environments exhibiting high levels of these conditions.
