Installation Environment
This product is capable for use in the environment of pollution degree 2*1 or equivalent.
*1 Pollution Degree 2 : Environment that may cause non-conductive pollution or transient conductive
pollution by frost. (IEC60664-1)
1. Installation Environment
Do not use this product in the following environment.
•
Location where the surrounding air temperature exceeds the range of 0 to 40
°
C
• Location where condensation occurs due to abrupt temperature changes
• Location where relative humidity exceeds 85%RH
• Location exposed to corrosive gases or combustible gases
• Location exposed to significant amount of dust, salt or iron powder
• Location subject to direct vibration or impact
• Location exposed to direct sunlight
• Location where the product may come in contact with water, oil or chemical droplets
• Environment that blocks the air vent [Refer to Installation and Noise Elimination Section]
When using the product in any of the locations specified below, provide a sufficient shield.
• Location subject to electrostatic noise
• Location where high electrical or magnetic field is present
• Location with the mains or power lines passing nearby
2. Storage and Preservation Environment
The storage and preservation environment should comply with the same standards as those for the installation
environment. In particular, when the machine is to be stored for a long time, pay close attention to environmental conditions
so that no condensation forms. Unless specially specified, moisture absorbency protection is not included in the package
when the machine is delivered. In the case that the machine is to be stored and preserved in an environment where
condensation is anticipated, take the condensation preventive measures from outside of the entire package, or directly after
opening the package.
Installation and Noise Elimination
1. Noise Elimination Grounding (Frame Ground)
2. Precautions regarding wiring method
(1) Twist the wires for the 24V DC power unit.
(2) Separate the communication line from the power line.
3. Noise Sources and Elimination
Carry out noise elimination measures for power devices on the same
power path and in the same equipment.
The following are examples of measures to eliminate noise sources.
(1) AC solenoid valves, magnet switches and relays
[Measure] Install a Surge absorber parallel with the coil.
(2) DC solenoid valves, magnet switches and relays
[Measure] Install a diode parallel with the coil. Use a DC relay with
a built-in diode.
4. Heat Radiation and Installation
Design and Build the system considering the size of the controller box, location of the controller and cooling factors to keep
the ambient temperature around the controller below 40
°
C.
System Configuration (Example)
Note : Have the 0V line in common for the 24V power supply for each controller (except for SCON).
Power Supply and Emergency Stop Circuit (Example)
There is no emergency stop function for Gateway Unit. Perform the emergency stop using the control on the
system side. CR is an emergency stop relay for the entire system. While the connector port for the teaching
pendant and PC is on, the contact signal of the emergency stop switch can be output externally, thus the
emergency stop circuit of the system can be constructed. Also, Switching on/off of the port can be performed
not only on the port switch on the main unit of Gateway Unit, but also by the external signal. Shown below is
the relation between switching on/off of the port and the emergency stop signal output.

SIO Communication Line Wiring Layout
There should be no problem to have a terminal block connection
instead of a 4-way junction.
Use a terminal block connection or direct-joint connection if
there is a concern that a faulty connection may occur as a result
of using the E-Con connector.
