HMC7000 Models
What is a HMC7000 Series?
The HMC7000 Series are combination HMI (human machine interface) and PLC (programmable logic controller) in one
unit. The HMC7000 can be used as a stand-alone unit capable of connecting directly to inputs and outputs (both digital
and analog sources) through the use of optional expansion I/O modules. These I/O modules are controlled using industry
standard ladder logic instructions built-in to the programming software. The HMC (human machine controller) also has a
display and keypad/touchscreen to allow a plant floor operator visual feedback as well as direct input to the industrial
automation system.
In addition, the HMC7000 can connect to external PLCs or other controllers via a serial connection. This flexibility
provides access to most major manufacturer PLCs such as Rockwell Automation (Allen Bradley), Schneider Electric
(Modicon Modbus), Siemens, GE Fanuc, Omron and many others.
Most important of all, the HMC7000 Series is specifically designed for harsh industrial environments. Every unit is rated
for CE (European Noise Immunity/Emissions standards), NEMA 4 rating, and UL listed for installations requiring a Class
I Division 2 product.

Installation
CE Compliance
The HMC7000 Series Graphic HMCs 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
graphic HMC.
Environmental Considerations
The HMC7000 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. Make sure that the unit is installed correctly
and that the operating limits are adhered to (see Specifications from Maple Systems website). Avoid installing the
HMC7000 Series in environments with severe mechanical vibration or shocks. Do not install the HMC in enclosures with
rapid temperature variations or high humidity. Either will cause condensation of water inside the device and eventual
damage to the HMC. Highly humid areas are also to be avoided. High humidity causes condensation of water in the unit.
Do not operate the HMC7000 Series in areas subject to explosion hazards due to flammable gases, vapors or dusts.
NEMA Rating
The HMC7000 Series is rated for NEMA 4/12 (indoor) or IP65 installations. This means that when the HMC is properly
mounted to a NEMA 4 panel or other NEMA 4 rated enclosure, the front enclosure of the HMC will provide protection to
the inside of the panel from splashing water, wind-blown dust, rain, or hose-directed water. The HMC must be installed
according to the instructions in this manual to be properly sealed.
Safety Precautions
Please observe the following precautions when installing the HMC. Failure to comply with these restrictions could result
in loss of life, serious personal injury, or equipment damage.
Warning: Do not operate the HMC in areas subject to explosion due to flammable gases, vapors, or
dusts
Warning: Do not connect the HMC to an AC power source. You will cause permanent damage to the
HMC.
Warning: Do not attempt to use a DC power supply that does not meet HMC power requirements. You
may cause malfunction or permanent damage to the HMC.
Warning: Do not power the HMC 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 HMC.

5 HMC7000 Series Installation Guide
Location Considerations
Care should be taken when locating equipment behind the HMC7000 to ensure that AC power wiring, PLC output
modules, contactors, starters, relay and any other source of electrical interference are located away from the HMC7000.
Particular care should be taken to locate variable speed drives and switching power supplies away from the HMC.
Control Panel Design Guidelines
Panel Preparation
A metal panel or mounting surface is required. The minimum thickness should be 15 gauge (0.059 in/3.3 mm) if coldrolled steel or hardened steel is used. Use 10 gauge (0.101 in/2.6 mm) if aluminum alloy (6061-T6 preferred) is used.
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.
Maximum thickness should be no more than 0.26” or 6.5mm.
The HMC should be mounted into a panel with a depth of at least 4 in. (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 HMC model are readily available for download from the Support CenterDimensional Drawings section of the Maple Systems website
Warning: The HMC requires a stiff, flat, smooth mounting surface free of blemishes, scratches, or pits in order that the
gasket seal properly to NEMA 4. 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 HMC is installed
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.

9 HMC7000 Series Installation Guide
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 HMC may occur. Connect the HMC chassis ground terminal
to a reliable earth ground with a low-resistance path.
Route all earth ground wires that lead from the HMC, the PLC, 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 HMC 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 HMC chassis ground terminal. Connect the
control panel to earth ground using a copper grounding rod close to the HMC 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 Technical Note #1027, “OIT Ground Wiring and
Electrical Noise Reduction,” which you can find in the Tech Notes section on our web site.
Connect HMC Chassis Ground to Control Panel
To reduce the possibility of electrical interference, connect the chassis ground terminal of the HMC to a clean earth
ground. Ensure that the HMC is grounded separately from other high-power systems. Use a single-point ground if
grounding more than one unit.
If the control panel is metal, make sure it is properly grounded. Then connect a short heavy gauge wire (#14 AWG) from
the chassis ground terminal of the HMC 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 HMC to a clean earth ground point located close to the panel.
NOTE: Do not use a ground that has an unstable impedance, such a painted screws, or ground subject to vibration.
