Specifications
Front Panels
The ePC series has NEMA 4/4X/12 sealed front panels when mounted in an appropriate NEMA
rated enclosure. See Chapter 2 for more details on installation and selection of an appropriate enclosure.
All four sizes have very similar front panels with different dimensions.
Figure 1.0: ePC Series Front Panel Comparison
The standard front panels are powder coated aluminum. The optional Stainless Steel front panel is type
304 and will not contain a logo pocket or logo on the front. The window area is clear polycarbonate when
ordered without a touchscreen. The touchscreen option is chemically strengthened glass covered by a
polyester overlay. The polyester overlay has better resistance to chemicals than the polycarbonate
window. Depending on the chemicals involved in your application consideration should be given to
choosing the proper window material. See Appendix X for a chart of some common chemical
resistances. In addition there is a Rack Mount front panel option for the ePC1900 (19” unit) only. This
front panel is powder coated aluminum and is 9U high with four rack mount spaced counter-bored
mounting holes on each side of the panel. This panel is not NEMA sealed when installed.

Chapter 2 - Installation of Computer
Panel Mount ePC-Series Unit installation
The panel mount versions of the ePC-Series 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.

nPC100 Unit Installation
The nPC100 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 ePC1900 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-Series 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-Series –EN units (except fanless version) have a filter
over the CPU fansink to filter incoming air. This filter 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.

Connecting Power to the ePC-Series
Connecting power to the Panel Mount, Rack Mount, and nPC100 units:
The ePC-Series and nPC100 units are powered from 100-240 VAC, 50/60 Hz or optionally from
24 VDC. Damage will occur if 100-240 VAC power is connected to an ePC-Series unit equipped
with the 24 VDC input power option. ePC-Series equipped units with the 24 VDC option will have a “-
DC” suffix in their model number such as ePC1500-CM440-1GB-XP-DC or ePC1500T-T2500-2GB-XP-
DC.
Because the ePC-Series (not –EN option) is UL 1604 listed for Hazardous Location use, (Class I
Division2, Groups A, B, C, D; Class II Division 2 Groups F and G: Temperature Code T4A), the units do
not have a power switch for switching off supplied power. Consideration should be give to the installation
of an appropriately rated external power switch if the application requires powering off the ePC-Series
unit.
Power is connected to the units through a removable Phoenix Contact plug (Phoenix Contact
P.N. 1777992) that allows for screw termination of field wiring. This plug is included with each unit and is
keyed to prevent installation in a unit with the wrong input voltage rating. When Field Wiring to these
terminals the use of 18 AWG or greater (12 AWG maximum) copper wire with 60ºC or 60/75ºC wire
insulation and the terminal tightening torque of 7.0 lb/in. (0.79 Nm) is required. The terminal screws
are shown in “Top View” below. Connect the field wiring according to the appropriate voltage in the table
below. Strip the wire insulation back on each conductor 6.5 mm (0.26 in) and assure that the remaining
wire is twisted together, not frayed, and clean. If an outer jacket over each conductor is utilized then strip
the outer jacket back an additional 19.0 mm (0.75 in) as shown in figure below. When installing the
conductors take care that there are not any stray strands of wire that can contact an adjoining connection.
Tinning of each lead can be utilized to prevent frays if desired. Optionally the included protective cover
can be utilized to prevent electrical shocks when handling the power connector and provide strain relief
for each conductor connection (see the following section for installation instructions). After the
connections are made, make sure the plug retention screws (the two screws shown in the “Front View”
below) are securely tightened. This will prevent the plug from pulling out. The use of these screws is
mandatory when the unit is utilized in applications requiring hazardous locations approvals.

Connecting Power to Enclosed (-EN) units:
The enclosed ePC-Series are powered from 100-240 VAC, 50/60 Hz only. Because these are
stand alone Type 1 devices and do not require an additional NEMA type enclosure, a different type power
connection is required. These units use a more standard IEC type power cord like found on most
computers. There is a retention clip that can be utilized to help retain the cord from falling out. A US
three prong cord is supplied. If another country connection method is required then an appropriate UL
recognized power cord can be chosen locally (not supplied by Nematron). Optionally available is an IEC
type connector that can be directly wired to for field wiring. This can be ordered separately from
Nematron and is part number PWR-AC-EN
Enclosed ePC-Series IEC Power Cable Power Cable Retention Clip Installed
I/O Cable Management
The ePC-Series units include a retention mechanism for securing USB connections. USB
connections are not secure and can easily fall out. The use of this mechanism is suggested for all
applications and is required for any hazardous locations installations. Simply remove the bracket insert
your USB cables through the bracket. Connect your USB cables to the unit and move the bracket into
position. Snugly push the bracket toward the USB connector and secure with the screw provided.
On the ePC panel mount, Rack Mount, and Enclosed units the USB bracket is a simple L shaped
bracket with cutouts to retain up to four USB cables and a mounting screw. On the nPC100 the bracket is
two pieces; one (flat piece) is secured to the bottom of the unit using two #4-40 screws and then the other
functions the same as the ePC-Series USB retention bracket.

Video and the Serial connections have jack screws in the connectors that can be utilized to
secure your cable end to the unit. Ethernet connections have a plastic tab that prevents the connection
from falling out. The keyboard/mouse port (splitter provided) is not secured and is intended for setup and
maintenance only when in an area that is known to be nonhazardous.
See the connecting power section for details on securing the power connections. In addition to
the USB Bracket there is an additional cable management bracket at the bottom of the units (N/A on
ePC1200) that can be utilized to strain relief cables. This is a flat bracket attached by 2 screws which can
be utilized to hold down cables or provides an attachment point for a cable tie to be used for securing
cables. Care should be taken to provide an adequate radius for any cable being utilized. Too tight a
radius can damage the conductors. When tightening this securing bar care should be taken not to over
crush cables; this can damage conductors.

Hard Drive Removal and Replacement
These products are equipped with an easily removable SATA hard drive. They are designed so
that there is no need to remove the cover on these units to change a hard drive. The only reason to
remove the cover will be to switch the configurable serial port from RS-485 to RS-422. See the
appropriate board manual included on the “Documentation and Driver” disk for procedure on changing
this port. The hard drive is simply removed by loosening the two thumbscrews and pulling the drive out.
Remove all power to the unit before removing the drive.
There are no cables to remove when pulling the drive from the chassis. Once the drive is
removed there are four screws on the back of the bracket that hold the drive. If the drive is being
replaced these screws secure the drive to the plate. To reinstall the drive simply insert the bracket with
hard drive attached into the chassis and slide forward. Completely push the drive in and secure the
thumbscrews before reapplying power to the unit.
Various hard drive options with a mounting bracket pre-installed are available for purchase from
Nematron. If a spare hard drive is required these are recommended. These spare hard drives can be
used with third party software to create complete system backups for your installation.

Installing the Touch Screen Driver Software
If your ePC is ordered with a touchscreen and an operating system the drivers will be pre-
installed. The ePC-Series utilizes a USB connection for the touchscreen, therefore the touchscreen will
only function with operating systems that can recognize and utilize USB connections. The driver
included with these units functions with Windows 2000, XP, VISTA, and Windows 7. If using the nPC100
with a touchscreen monitor the appropriate driver will be included with the monitor.
Operating System Recovery
If for some reason your operating system needs to be reinstalled Nematron provides an
Operating System or Recovery disk. The procedure for this is dependent on the operating system.
Because this series does not have an integrated DVD you will need a USB DVD-ROM drive. In some
cases you will also need the “Documentation and Driver” disk that is included with each unit.
The ePC-Series products are only shipped with Windows XP Professional SP3, Windows Vista
Business Edition, and Windows 7 Professional. Use of other operating systems is not recommended and
not supported.
Windows XP Professional SP3 for Embedded Systems
Standard Windows XP operating system disks are no longer available from Microsoft. In order to
continue shipping Windows XP for Automation applications, Nematron had to switch to a different license
scheme, Windows XP Professional SP3 for Embedded Systems. This is not Embedded XP it is simply a
different license procedure. By switching to this license Nematron had to create a system recovery disk.
This disk is very specific to the platform and options that are included on your unit. Do not attempt to use
a recovery from one type of unit on another, it may not work. This recovery disk installs the factory image
with all drivers installed. On these units you will need an USB DVD-ROM. Follow the instructions on the
recovery DVD for installation. When installing the image from this DVD it will not be “Activated”, unlike
when you received the unit. You may need to set the video resolution after loading the image depending
on the unit you are loading.
Windows Vista and Windows 7
Windows Vista and Windows 7 are supplied with an OEM operating system license and disk. .In
order to reinstall these operating systems the operating system is installed first via the included disk and
then the “Documentation and Driver” disk must be utilized to install the approved drivers for chipset,
video, Ethernet, and touchscreen if not functional during operating system installation. Use of different
drivers than included on the disk are not recommended and not supported.
