Static Awareness
Do NOT remove the rear cover of your OMI5000 Series product – doing
so will void your warranty. When the rear cover is removed the circuitry
inside is exposed to possible damage by electrostatic discharge during
handling. Minimize the possibility of electrostatic discharge by:
Discharging personal static by grounding yourself prior to
handling the OMI.
Handling the OMI at a static-free grounded workstation.
Connecting the frame ground ( ) connector of the OMI to a
clean earth ground.
Placing the OMI in an antistatic bag during transport.

Installation of OMIs
CE Compliance
The OMI5000 Series Open HMIs have been tested to conform to
European CE requirements, which meet or exceed the noise emissions
and immunity requirements as set forth in the EN55022 (Emissions) and
EN55024 (Immunity) standards. The products are designed to withstand
electrical noise in harsh industrial environments. They also conform to
requirements that limit electrical emissions. However, this does not
guarantee that the products will be totally immune from possible
malfunction in cases where severe electrical noise occurs. Therefore, we
strongly recommend that you follow the guidelines outlined in this guide
for proper wire routing and grounding to insure the proper operation of
your Open HMI.
NEMA Rating
The OMI5000 Series is rated for NEMA 4/12 (indoor) or IP65
installations. This means that when the OMI is properly mounted to a
NEMA 4 panel or other NEMA 4 rated enclosure, the front enclosure of
the OMI will provide protection to the inside of the panel from splashing
water, wind-blown dust, rain, or hose-directed water. The OMI must be
installed according to the instructions in this manual to be properly
sealed.
1010-1017 Rev. 00 3
Environmental Considerations
The OMI5000 Series is designed to operate in temperatures from 0° to
50°C (32° to 122°F). It is intended for indoor installations and may not
be suitable for use in certain outdoor applications. Avoid installing the
OMI5000 Series touchscreens in environments with severe mechanical
vibration or shocks. Do not install the OMI in enclosures with rapid
temperature variations or high humidity. Either will cause condensation
of water inside the device and eventual damage to the OMI.
Safety Precautions
Please observe the following precautions when installing the OMI.
Failure to comply with these restrictions could result in loss of life,
serious personal injury, or equipment damage.
Warning: Do not operate the OMI in areas subject to explosion
due to flammable gases, vapors, or dusts.
Warning: Do not connect the OMI to an AC power source. You
will cause permanent damage to the OMI.
Warning: Do not attempt to use a DC power supply that does
not meet OMI power requirements. You may cause malfunction
or permanent damage to the OMI.
Warning: Do not power the OMI with a DC power supply used
for inductive loads or for input circuitry to the programmable
logic controller. Severe voltage spikes caused by these devices
may damage the OMI.
Control Panel Design Guidelines
Pay careful attention to the placement of system components and
associated cable routing. These items can significantly enhance the
performance and integrity of your control application.

Control Panel Grounding
The control panel must be connected to a good, high-integrity earth
ground both for safety considerations and shielding purposes. Maple
Systems cannot overemphasize the importance of good grounding. If you
fail to use good grounding procedures during installation, sporadic
malfunction of the OMI may occur:
Connect the OMIs chassis ground terminal to a reliable earth ground
with a low-resistance path.
Route all earth ground wires that lead from the OMI, the power supply,
and the line filter to a central earth ground point such as a barrier strip.
This will ensure that no ground current from one device influences the
operation of the other devices.
Connect the OMI chassis ground terminal to the control panel door using
a heavy-gauge short braided cable or ground wire to minimize resistance.
Connect the power cable’s shield wire to the OMI’s chassis ground terminal.
Connect the control panel to earth ground using a copper grounding rod
close to the OMI and control panel.
Hinged doors on control panels do not provide a long-term electrical
connection to the rest of the enclosure. Corrosion develops over time and
prevents good electrical contact. For this reason, a separate wire braid
should be installed from the hinged control panel to the rest of the
enclosure.
For a more in-depth overview of ground wiring techniques, refer to
1010-1017 Rev. 00 5
Technical Note #1027, “OIT Ground Wiring and Electrical Noise
Reduction,” which you can find in the Support Center Technical Notes
section on our web site.
Connect OMI Chassis Ground to Control Panel
To reduce the possibility of electrical interference, connect the chassis
ground terminal of the OMI to a clean earth ground. If the control panel
is metal, make sure it is properly grounded. Then connect a short heavygauge wire (#14 AWG) from the chassis ground terminal of the OMI to a
mounting bolt on the control panel door. The mounting bolt must have
good electrical contact to the control panel; scrape away any paint that
may be covering the panel to provide a good connection.
NOTE: If the control panel is made of a non-conductive material, it is
essential that you connect the chassis ground terminal of the OMI to a
clean earth ground point located close to the panel.
Figure 2: Chassis Ground Connection
Power Supply Selection
The power supply used to power the OMI should provide an output of
+24 VDC ±20% measured at the HMI power terminal block. A 24VDC
regulated power supply dedicated to the OMI is recommended. Use a
power supply with adequate current rating based upon your particular
model (visit the Support Center Specifications page on our website).
A power line filter installed at the AC input to the OMI power supply is
highly recommended as a safeguard against conducted RF noise, which
is often present on factory power lines. The wires connecting the output
of the power line filter to the power supply should be kept as short as
possible to minimize any additional noise pickup. The case of the power
line filter should be connected to a quiet earth ground. The power line
filter should have a current rating of at least 3 Amps with common mode
1010-1017 Rev. 00 6
and differential mode attenuation. In applications that may have high
frequency noise present, we also recommend using a resistor (~1 MΩ)
and capacitor (~4700 pF) in parallel to clean earth ground on the DC
output of the power supply.
Do not use the power supply used to provide power to the OMI to power
switching relays, solenoids, or other active devices.
Figure 3: Power Line Filter Connection
Cable Routing and Noise Immunity
Follow these guidelines when routing cables to the OMI:
Always route the OMI communication cable and the power cable
away from any AC voltage or rapidly switching DC control
lines.
Never bundle the OMI cables together with 120VAC power
wires or with relay wiring.
Try to keep at least 8 inches (20 cm) of separation between the
OMI cables and other power wiring. If voltages greater than
120VAC are used in the system, greater separation is required.
If the OMI cables must come near AC wiring, make sure they
cross at 90 degrees.
Run AC power wires in a separate grounded conduit to reduce
electrical noise interference.
Keep the cable lengths for the OMI as short as possible. Do not
coil excess cable and place it next to AC powered equipment.
Cover any equipment used in the enclosure that operates at high
frequency or high current levels with a grounded metal shield.
1010-1017 Rev. 00 7
Installation
It is necessary to follow all installation procedures described in this
chapter for electrical noise immunity and CE compliance.
Your Maple Systems OMI is designed to connect easily to your
Controller. External rear connectors provide quick connections for
power, communications and programming wiring.
Connect the OMI to Power
Use the separate 3-position terminal block supplied with the OMI to
provide power to the OMI.
The power cable for the OMI should be 18AWG, 2-conductor wire with
a shield drain wire and protective shield (foil/braid). You may buy cable
P/N 6030-0009 by the foot from Maple Systems to make your own
power cable.
Always run the DC ground wire directly back to the signal return of the
power supply. Do not use the chassis ground wire as your signal return.
Caution: To prevent possible damage to the OMI, we
recommend waiting ten seconds after removing power to the
OMI before applying power again.

Maple Systems cable P/N 6030-0009):
NOTE: The power connector on the OMI5000 Series uses a 3-position
terminal block with screw-down clamps. Lugs are not required.
Panel Preparation
A metal panel or mounting surface with a minimum thickness of 15
gauge (0.059 in/3.3 mm) if cold-rolled steel or hardened steel, or 10
gauge (0.101 in/2.6 mm) if aluminum alloy (6061-T6 preferred) is
required. Thinner panels or surfaces may bow between the mounting
clamps and not form a seal with the gasket. Make sure all supplied
mounting clamps are used and that the panel does not flex or bow more
than 0.010 in. to ensure a proper seal.
1010-1017 Rev. 00 9
The OMI should be mounted into a panel with a depth of at least 4 in.
Hold the OMI against
the panel until all screw
clamps are in position
(105 mm). Allow a clearance of at least 1 in. (25 mm) on each side for
mounting hardware. Consider proper clearance for cable connections
when mounting.
NOTE: Cutout dimensions for each particular OMI model are readily
available for download from the Support Center-Dimensional Drawings
section of the Maple Systems website.
The area of the panel or mounting surface where the gasket comes into
contact must be flat and free of scratches, pits, and other features that
prevent the gasket from sealing properly. If the panel or mounting
surface is not uniform, thick, flat, stiff, or smooth enough, then a sealant
such as silicone may be required.
NOTE: Clean and deburr the panel cutout before the OMI is installed.
Warning: The OMI requires a stiff, flat, smooth mounting
surface free of blemishes to seal properly to NEMA 4.

clamp as shown above. Position the screws so that the ends don’t
protrude through the clamp’s hole.
2. Set the OMI in the panel cutout and hold it in place until all
clamps are in position.
3. Tighten the screw clamps in an even pattern until all are
uniformly snug.
Caution: Do not over-tighten the screws beyond snugness or
you may damage the housing.
Mounting Clamp Placement
REINSTALLATION: If, at anytime, you are required to reinstall an
OMI into a panel, be aware that the gasket will take a ‘set’ to the panel
and may no longer provide an adequate NEMA 4 seal Therefore, for best
results, we recommend that you replace the gasket if reinstallation is
required.
Configuration Wiring
To install application software and upload/download files on your OMI,
you may wish to connect your computer to the Open HMI. Connection
can be done via the serial port, USB port or the Ethernet port.
USB
To transfer files via the USB client port on the OMI, you must purchase
a USB download cable (Maple P/N 7431-0115). You must also install a
USB device driver onto your computer that supports connection to the
OMI. Please follow the instructions located in your OMI5000
Operations Manual (Windows CE Embedded 6.0 Professional Edition)
[Maple P/N 1010-1016] to install the USB driver onto your computer.

To connect your OMI to your computer via the10/100 Base-T Ethernet
port requires a standard Ethernet crossover cable (Maple P/N 7431-
0104). If you use a switch or router between the computer and the OMI,
use a straight-thru cable (Maple P/N 7431-0103).
Once a connection is made, you will need to install a data
synchronization program use as Microsoft's ActiveSync onto your
computer. ActiveSync provides the ability to manually transfer files to
the OMI5000 or download application software. ActiveSync is available
from Microsoft's support website for mobile applications.
