INTRODUCTION
Thank You for your interest in AVG Automation’s latest unique offering, the EZ7 Series HMI.
EZ7 HMI is two piece products: Front part consisting of display (and touch screen) housed in metal,
and a back part that has HMI processor. Front part is installed on the front of the control cabinet,
while the back part is installed on the back of the control cabinet door. The two are connected using a
cable.
This construction has following benefits:
•No large cutouts for the HMI, only drill holes for the studs, and a hold for cable
•Easily replace worn-out touch screens instead of changing whole unit
•If required, upgrade to larger display sizes without need to change the back.
•Use the same EZTouch editor that is used for other EZTouch families of HMI
•Support for a variety of PLC Protocols including DH+ and Remote I/O

INSTALLATION
4.1 GUIDELINES
Safety Considerations
Please follow all applicable local and national codes to ensure maximum safety of the equipment and
personnel. The installation and operational environment must be maintained per the latest revision of
these codes.
You are responsible to determine the codes to be followed and to verify the compliance of
equipment, installation, and operation with the latest revision of these codes.
It is an absolute must to follow all applicable sections of:
•The National Fire Code
•The National Electrical Code (NEC)
•The National Electrical Manufacturer's Association (NEMA) codes
Safety Guidelines
Safety is the most important element of a proper system installation. Adhering to these safety
considerations ensures the safety of yourself and others, as well as the condition of your equipment.
We recommend reviewing the following safety guidelines:
1) Disconnecting Main Power
The main power switch should be easily accessible to the operators and maintenance
personnel. It is important to make sure that all other sources of power including pneumatic
and hydraulic are de-energized before starting the work on a machine or process controlled by
an EZ EZ7 Series HMI.
2) Safety Circuits
Most of the machines are installed with safety circuits such as limit switches, emergency stop
push buttons, and interlocks. These circuits should always be hardwired directly to the EZ7
Series HMI. These devices must be wired in series so that when any one device opens, the PLC
is automatically de-energized. This removes power to the machine. These circuits should not
be altered in any case, since this could result in serious injury or damage to the machine.
3) Fail-Safe Operation
Our products are not fault-tolerant. They are not designed or intended for use as online
control equipment in hazardous environments requiring fail-safe performance, such as in
operation of nuclear facilities, aircraft navigation or communication systems, air traffic control,
direct life-support machines, weapons systems, clutch control systems on presses, in which
the failure of the product could lead directly to death, personal injury or severe physical or
environmental damage. External fail-safe and/or redundant components are required to make
your control system fail-safe.

7 / 31
Installation Considerations
Our products have been designed and tested for operation in the most demanding industrial
environments. Modern solid-state industrial controls are complex electronic equipment that operate
at low levels of voltage and current, co-existing with components that operate at much higher levels
of power. The difference in operating power characteristics between the high and low power control
devices creates the possibility of unwanted signals being generated, thus causing interference. The
interference, which is a by-product of electrical noise, is not present at all times. However, if it
appears at random and for brief periods of time, it can cause disruptions and errors in the operation
of a control system.
Enhancement of a system’s noise level immunity and its tolerance to other environmental hazards can
be accomplished by following proper system installation guidelines. The recommendations are of a
general nature and constitute good industrial installation practice.
General Environmental Considerations
Avoid installing EZ7 Series HMI in areas where the following conditions may exist:
•Environmental temperatures above or below those specified by the EZ7 Series HMI
•Prolonged exposure to humidity and liquids which may be sprayed or splashed on the
equipment
•Dusty environments where airborne particles may accumulate on equipment causing
reduction of heat dissipation and reduction in effective electrical spacing between
components
•Areas with excessive vibration
•Areas with high-radiated electrical noise, such as near fields of transmitting antennas and
areas in close proximity of arc welding stations
Physical Layout in a Control Cabinet
When possible, cabinets housing electronic equipment should be designed with provisions for natural
or forced ventilation to facilitate heat dissipation. Observe the following rules for cabinet
installation:
•Heat generating equipment (power supplies and other
heat inducing components) should be installed toward the
top of the cabinet. The lower space in the cabinet is cooler
than the top area.
•Install heat-sensitive components in the lower section.
•Provide enough space between components to allow a
free flow of air for better heat dissipation.
•Provide the maximum possible physical separation between solid state and electromechanical
controls. If possible, the electromechanical controls (motors, starters, solenoids, etc.) should
be housed separately or at the farthest point when enclosed within the cabinet.
•We recommend that the EZ7 Series HMI have a minimum clear space of 2" on all sides for
adequate ventilation as shown in the image on the left.

Electrical Considerations
This section is designed to provide you with a very basic understanding of electrical noise and how to
keep it away from CPUs. Industrial plants have a number of generators of electrical noise that are
sometimes also referred to as Radio Frequency Interference (RFI). Anytime an inductive load like a
motor, motor starter, or solenoid is turned off, it generates a burst of excess energy that has to flow
back to ground, just like electrical energy from a lightning storm has to flow back to Earth. RFI is short
bursts of electrical energy at very high frequencies. Other sources include RF Welders or Radio
Transmitters.
Effect of RFI on Electronic Automation Equipment
Electronic controls use faster and faster CPUs today. These CPUs are also operating at 2.5V to 5VDC
logic level power supply. RFI, if allowed to enter the CPU inside, is a killer of logic. A CPU under this
environment loses its brain and behaves erratically. A smart industrial-grade CPU like the EZ7 Series
HMI Card Engine, when faced with RFI, halts its operation instead of giving false outputs.
Types of RFI
RFI enters electronic controls in two ways: radiated RFI or conducted RFI. For most practical purposes,
electronic devices, unless sitting right next to a powerful RFI transmitter, will not be affected by noise
because air space severely attenuates such interference. On the other hand, conducted RFI travels
over conductive surfaces such as power supply wires, electrical wiring of field devices, and worst of
all; improper ground planes.
Equipment cabinets usually incorporate one or two doors and/or hinged cabinet panels. Relying on
door hinges and swinging panels for a good metallic bond between hinged parts and the main body of
the cabinet does not insure adequate grounding. Instead, the use of ground straps is
recommended. It is vital for the reliable operation of any electronic device to have any of its metallic
surfaces well ground to Earth. This not only provides for safe operation, it will also drain out any
conducted RFI to Earth, away from the CPU's signal ground.
Shielding from RFI
Shielded Cables
Power cables, I/O cables or wiring, and communication cables should all be separate so that they do
not couple the conducted RFI on any of these wires/cables. Another path for RFI into the PLC is
through its RS232 port. Hence, the cables to this port must be shielded properly.
Equipment Cabinets
As mentioned, equipment cabinets typically incorporate one or two doors and/or hinged cabinet
panels. In addition, sub-panels may be utilized on those electronic controls and electromechanical
items that are mounted. The goal is to create a medium for mounting the equipment and ensure
grounding of the control’s chassis to it. However, the door hinges and swinging panels by themselves
are not enough to ensure adequate grounding.

9 / 31
Similarly, the equipment enclosures are generally either
painted or anodized. Mounting of painted or anodized
enclosures to like surfaces also does not ensure good
metallic contact between the equipment chassis and
cabinet. It is imperative that the equipment chassis are
grounded such as through the use of grounding straps as
illustrated below.
Cabinet Wiring
The wiring of the EZ7 Series HMI to the “field” outside the cabinet must be by design. The wiring
cannot be random in order to get the various points of the cabinet and the “field” electrically
connected. Below are some general rules that apply in most situations:
Provide a separate power source to electronic controls and keep this power bus away from any I/O
power.
The cabinet should be wired with a safety ground (the main safety ground wire gauge is determined
by the cabinet’s total current consumption) and in accordance with all electrical code requirements.
Once the cabinet doors, stationary sub-panels and swing-out sub-panels have been “strapped” to the
main cabinet, it is not necessary to run safety ground wires from the equipment chassis terminals to
the main safety ground connection.
The safety ground terminal of each component can, and should be, connected with the shortest wire
possible, to the cabinet or sub-panel frame.
Plan the wiring routing. Keep all switched power in separate ducts and if there is AC and DC power
being switched, keep the wiring of each branch separate from all wires and cables carrying low level
signals.
Keep all three phase power outside of the cabinet, but if it becomes necessary, keep the runs as short
as possible and maintain the maximum possible distance between the three phase bus and all other
wiring.
Primary power leads to the control equipment (Base power terminals) should be made with a two
wire twisted cable with approximately 12 turns per foot. The length of these cables should be kept to
a minimum, and to the greatest extent possible, such cable runs should be kept separate from other
wiring.

4.3 MOUNTING INSTRUCTIONS
EZ7 comes in two parts:
1. HMI Processor Unit, mounted using 4 studs on backside of the control cabinet door
2. Display Unit, mounted on studs (number of studs depends on size).
A cable connects the two parts, which passes through a ¾” hole in the cabinet door.
To mount the unit, in summary:
•Mark location of all holes
•Drill holes for the back and front unit mounting studs. (Please note that the mounting holes for
the back unit require countersink holes.
•Drill ¾” hole for the cable.
•Connect display cable to the back side and mount the back side
•Thread the display cable through ¾” cable hole to the other side.
•Connect cable to front side and mount the front unit.
These steps are described below with pictures:
The EZ7 is stud mounted. All the necessary mounting hardware is provided with the unit. Both the
processor and the HMI screen have studs with nuts provided. Below is a full installation guide with
step by step instructions.
1. Use the provided screen with screw hole indicators to drill holes in your control cabinet.
