5Installation
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 EZ7 Series TouchPLC.
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 TOUCHPLC. 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.
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.

Page 9of 44
EZ7-TouchPLC Micro
General Environmental Considerations
Avoid installing EZ7 Series TouchPLC in areas where the following conditions may exist:
Environmental temperatures above or below those specified by the EZ7 Series TouchPLC
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 TOUCHPLC 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
TOUCHPLC 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.

Page 10 of 44
EZ7-TouchPLC Micro
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.
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 TOUCHPLC 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.
