NEMA rated enclosure. See Chapter 2 for more details on installation and selection of an appropriate
enclosure. All three sizes have very similar front panels with different dimensions.

ePC1550 ePC1750 ePC1950
Figure 1.0: ePC-Plus Series Front Panel Comparison

The standard front p anels are p owder coat ed aluminum . The optiona l Stainless Steel front panel is type
304 and will not contain a logo pock et or logo on the f ront. T he window area is c lear pol ycarbo nate when
ordered without a to uchscreen. The touchsc reen option is chemicall y 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.

In addition to the pane l m ounted versio ns ther e is a di spla y-less “node” vers ion, the nPC200. T his uni t is

Chapter 2 - Installation of Computer

The panel mount versions of the ePC-Plus units are inten ded to be mounted in and used wher e
NEMA 1, NEMA 4/4x and NEMA 12 type enc losures 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 enc losure constructed from 14-gaug e or hea vier ste el. T he com puter uses “U”-shaped
clips and a special gasket to achieve the proper seal.

When selecting an enclos u re r em em ber to allo w ad eq uate s pace ar oun d th e r ear of the computer
for good air flow. Do not bl oc k air flow from below or a bov e th e monitor. If possible mount the computer in
a vertical orientation. T he unit is designed t o work in e nvironments up to 50 degrees Cent igrade ambient
temperature inside the enc losure. Remember to account for heat diss ipated from other equipment that
may be installed inside the same enclosure.

To install the computer , make a cutout accordin g to the diagrams below in one of the walls of
your NEMA enclosure. N ex t hold the u nit in plac e whi le you ins tall t he m ounting clips. T ighten the c lips
to the point were the b ack of the unit’s f ront bezel j ust begins to co ntact the f ront of the N EMA encl osure.
The use of an adjustable torque driver is recommended. The screws should be tightened to 8 inch­pounds. Tighten the clips i n a cross pattern. This will help to develop an even pr essure on the sealing
gasket. DO NOT OVER T IGHTEN AS DAMAGE CAN RESULT IN THE COMPUTER C AUSING LOSS

OF SEALING INTEGRITY.

nPC200 Unit Installation

The nPC200 is inte nded to be mounte d on the f lat sur face on th e insi de of a NEMA T ype 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 enclosu re remember to allow adequate space aro und the computer for good
air flow. Do not block air flo w around the unit except for the m ounting surface. The computer can be
mounted on a horizontally or vertically to a wall or shelf within th e enc l osur e. The unit is designed to work
in environments up to 50 degr ees Centigrade ambient temperatur e 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 m ount front panel is intended to be mounted to a 19. 0” wide rack in a
NEMA Type 1 or better enclos ure. The unit can be mounted using standard r ack 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 r ack. This unit is not NEM A s eal ed 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 flo w. The unit is designed to work in environm ents up to 50 degrees Centigrad e
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-Pl us products ar e intende d to be s tand-alone N EMA T ype 1 units. T hese are
required to be mounted to a VESA style mount with a m inimum load rating of 40 pou nds. A desktop
stand, wall mount, or articulat ing arms are examples of VESA style mounts that can be utilized. These
units are vented for air flow and ar e not dust or water proof. Care should be tak en to not utilize these
units in areas where h igh concentrat ion of part iculate m atter or moisture are pr esent. If these conditions
do exist then the us e of the pane l mount versions in an appropr iate NEMA 4, 4x, or 12 enc losure shou ld
be considered. The warranty may be voided if high levels of moisture or particulate matter are
determined to be the c a us e of a f ail ur e. T he eP C -Plus –EN units h ave filters on the rear to f i lter incoming
air. These filters should be c arefully removed and cl eaned periodicall y depending on service c onditions.
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 th e enclosure. Impeding the airflow arou nd this unit or clogged filters will sever ely
affect the reliability of the unit by raising the internal tem perature. Assure that there is adequate airf low
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 ins ide the unit. As stated previous ly 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 Panel Mount, Rack Mount, and nPC120 units:

The ePC-Plus and nPC200 un its are po wered f rom 100-240 VAC, 50/60 H z or op tionally fr om 24
VDC. Damage will occu r if 100-240 VAC power is connected to an

24 VDC input power option. ePC-Plus e quipped units with t he 24 VDC opt ion wil l have a “-D C” suf fix in
their model number such as ePC1550-MC5500-1GB-HD-DVD-XP-DC or ePC1550T-T7500-2GB-HD-

DVD-XP-DC.

Because the ePC-Plus (not –EN option) is UL 1604 listed for Hazardous Locat ion use, (Class I
Division2, Groups A, B, C, D; Class II D ivision 2 Grou ps F and G: Tem perature Code T4A), the u nits do
not have a power s witch fo r switchin g off s upplied po wer. Cons ideration s hould be give to t he insta llation
of an appropriatel y rated external power switch if the application r equires 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 f or scr ew term ination of field wir ing. This p lug is includ ed with e ach unit and is
keyed to pr event installation in a u nit with the wrong input vo ltage rating. When Field Wiring to these

terminals the use of 18 AWG or greater (12 AWG maximum) copper w ire with 60ºC o r 60/75ºC w ire
insulation and the terminal tightening torque of 7.0 lb/in. (0.79 Nm) is required. The terminal screws

are shown in “T op View” below. Con nect the f ield wir ing acc ording to the ap propr iate volt age i n the table
below. Strip the wire insula tion back on each conductor 6.5 mm (0.26 in) and assure that the rem aining
wire is twisted toget her, not f rayed, and c lean. If an outer j acket over each co nduc tor is util ized then s trip
the outer jacket back an additional 19.0 mm (0.75 in) as shown in figure below. When installing the
conductors take care t hat there ar e not a ny stray strands of wire that can c on tac t an adj oi ni ng conn ec tio n.
Tinning of each lead can be utilized to pre vent frays if desired. Optionally the inc luded protective cover
can be utilized to prevent electr ical shocks when handling the power conn ector and provide strain relief
for each conductor connection (see the following section for installation instructions). After the
connections are made, m ake sure the plug retention screws (the two screws sho wn 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.

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 pre­installed. 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 nPC200
with a touchscreen monitor the appro priat e driver w i ll be inc luded w ith 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 US B 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.
