Safety Precautions
CompoNet Gateway Unit for CC-Link Operation Manual
Always input the voltage and current to the Unit within the
specified ranges.
Using a voltage or current outside the specified range may result
in malfunction or fire.
Do not touch any part of the terminal section or disassemble the
Unit and touch internal parts while the power is being supplied.
Do not apply power while the cover is open.
Doing so may result in electric shock.
Fail-safe measures must be taken by the customer to ensure
safety in the event of incorrect, missing, or abnormal signals
caused by broken signal lines, momentary power interruptions, or
other causes. Serious accidents may result from abnormal
operation if proper measures are not provided.
Provide safety measures in external circuits (i.e., not in the
Programmable Controller), including the following items, to
ensure safety in the system if an abnormality occurs due to
malfunction of the PLC or an external factor affecting the PLC
operation.
Serious accidents may result from abnormal operation if proper
measures are not provided.
• Emergency stop circuits, interlock circuits, limit circuits, and
similar safety measures must be provided in external control
circuits (i.e., not in Slave Units or Repeater Units).
• The outputs from Slave Units or Repeater Units may remain
ON or OFF due to deposits on or burning of the output relays,
or destruction of the output transistors. As a countermeasure
for such problems, external safety measures (i.e., not in Slave
Units or Repeater Units) must be provided to ensure safety in
the system.
• When the 24-VDC output (service power supply) from a Slave
Unit or Repeater Unit is overloaded or shortcircuited, the
voltage may drop and result in the outputs being turned OFF.
As a countermeasure for such problems, external safety mea-
sures (i.e., not in Slave Units or Repeater Units) must be pro-
vided to ensure safety in the system.
WARNING

Safety Precautions
10 CompoNet Gateway Unit for CC-Link Operation Manual
Confirm safety at the destination slave device before changing or
transferring parameters to another node. Changing or
transferring parameters without confirming safety may result in
unexpected equipment operation.
The output status from a slave device when problems occur in
communications will depend on the specifications of the slave
device. When using devices with outputs, confirm operating
specifications for communications error and implement suitable
safety measures.

Precautions for Safe Use
CompoNet Gateway Unit for CC-Link Operation Manual
Precautions for Safe Use
Observe the following precautions when using a CompoNet Gateway Unit for CC-Link.
zPower Supply
• Always use the power supply voltages specified in this manual.
• Take appropriate measures to ensure that the specified power with the rated voltage and frequency is
supplied. Be particularly careful in places where the power supply is unstable.
• Always turn OFF the power supply to the PLC, Gateway Unit, Slave Units, and communications
before attempting any of the following.
• Mounting or dismounting any Units
• Assembling Units
• Setting rotary switches
• Connecting or wiring cables
• Connecting or disconnecting connectors
zInstallation
• Install and wire Units correctly as described in this manual.
• Before touching a Unit, be sure to first touch a grounded metallic object in order to discharge any
static build-up.
• Make sure that the terminal blocks, connectors, communications cables, and other items with locking
devices are properly locked into place.
• When mounting Units to DIN Track or mounting brackets, mount them securely.
• Make sure that all the Unit mounting screws and cable connector screws are tightened to the torque
specified in this manual.
• Use only the specified communications cables and connectors.
• Use correct wiring parts and wiring tools when wiring the cables in the CC-Link and CompoNet sys-
tems.
zWiring
• Wire Units correctly as described in this manual.
• Double-check all wiring and switch settings before turning ON the power supply.
• Confirm polarity before wiring terminals.
• Observe the following precautions when wiring communications cables.
• Separate the communications cables from power lines and high-tension lines.
• Do not fold communications cables.
• Do not pull on the communications cables or bend them past their natural bending radius.
• Always lay communications cable inside ducts.
• Observe voltage specifications when wiring communications paths and power supplies and when wir-
ing I/O crossovers. Incorrect wiring may result in malfunctions.
• Do not apply voltages or connect loads to the Output Units in excess of the maximum switching
capacity.
• When using Flat Cable I (standard or sheathed) or Flat Cable II (sheathed) for more than one Com-
poNet system, do not bundle the Flat Cables and separate them from each other by at least 5 mm.
• Do not apply power while the cover is open.
• Use only the specified communications cables and connectors.
• Observe the connection distance specifications when connecting communications cables.
• Make sure that metal scraps do not enter a Unit when wiring or processing it.

Precautions for Safe Use
12 CompoNet Gateway Unit for CC-Link Operation Manual
zHandling
• Use the special packing box when transporting a Unit. Also, protect the Unit from being exposed to
excessive vibration or impact during transportation.
• Do not drop the Units or expose them to excessive vibration or impact. Doing so may result in failure
or malfunction.
• Check the user program for proper execution before actually running it on the Unit.
• Do not attempt to dismantle the Unit for repairs or modify it in any way.
• Confirm that no adverse effect will occur in the system before attempting any of the following.
• Changing the operating mode of the PLC
• Starting or stopping the user program
• Force-setting/force-resetting any bit in memory
• Changing the present value of any word or any set value in the user program
• Performing I/O tests
• Using the user compensation functions for an Output Unit
• Do not use organic thinners to clean the Unit. Use commercially available alcohol.
zExternal Circuits
• Install external breakers and take other safety measures against short-circuiting in external wiring.
• Fail-safe measures must be taken by the customer to ensure safety in the event of incorrect, missing,
or abnormal signals caused by broken signal lines, momentary power interruptions, or other causes.
• Construct the control circuits so that the power supply to the CompoNet Gateway Unit turns ON only
after the power supply to I/O Slave Units. If the power supply to I/O Slave Units is turned ON after the
power supply to the CompoNet Gateway Unit, normal operation may be temporarily inhibited.

13
Precautions for Correct Use
CompoNet Gateway Unit for CC-Link Operation Manual

Conformance to EC Directives
14 CompoNet Gateway Unit for CC-Link Operation Manual
Conformance to EC Directives
Applicable Directives
• EMC Directive
Concepts
zEMC Directive
The CompoNet Gateway Unit is an electrical device that is built into other machines. To enable more
easily building it into other machines, it has been checked for conformity to EMC standards.* EMC-
related performance of the Unit will vary depending on the configuration, wiring, and other conditions of
the equipment or control panel on which it is installed. Whether the products conform to the standards
in the system used by the customer, therefore, must be checked by the customer.
*Applicable EMC (Electromagnetic Compatibility) standards are as follows: EMS (Electromagnetic Susceptibility):
EN 61131-2 and EN 61000-6-2, EMI (Electromagnetic Interference): EN 61131-2 and EN 61000-6-4 (Radiated
emission: 10-m regulations).
zConformance to EC Directives
The CompoNet Gateway Unit complies with EC Directives. To ensure that the machine in which the Unit
is used complies with EC Directives, the Unit must be installed as follows:
• The Unit must be installed within a control panel.
• You must use reinforced insulation or double insulation for the DC power supplies for communica-
tions, internal power, and I/O. The DC power supplies must provide stable power even when a
momentary power interruption of 10 ms occurs in the input. *
• Products complying with EC Directives also conform to the emission standards (EN 61131-2 and EN
61000-6-4). Radiated emission characteristics (10-m regulations) may vary depending on the config-
uration of the control panel used, other devices connected to the control panel, wiring, and other con-
ditions.
• Compliance was confirmed for I/O wiring of less than 30 m.
* EMC standard compliance was confirmed with an OMRON S82J Power Supply.
• This is a Class A product (designed for industrial environments). Radio interference may occur if it is
used in a residential area. If that occurs, suitable countermeasures will be required.
