SAFETY PRECAUTIONS
(Read these precautions before using this product.)
Before using this product, please read this manual and the relevant manuals carefully and pay full attention
to safety to handle the product correctly.
The precautions given in this manual are concerned with this product only. For the safety precautions of the
programmable controller system, refer to the user's manual for the CPU module used.
In this manual, the safety precautions are classified into two levels: " WARNING" and " CAUTION".
Under some circumstances, failure to observe the precautions under " CAUTION" may lead to serious
consequences.
Observe the precautions of both levels because they are important for personal and system safety.
Make sure that the end users read this manual and then keep the manual in a safe place for future
reference.
[Design Precautions]
WARNING
Configure safety circuits external to the C Controller module to ensure that the entire system
operates safely even when a fault occurs in the external power supply or the C Controller module.
Failure to do so may result in an accident due to an incorrect output or malfunction.
(1) Configure external safety circuits, such as an emergency stop circuit, protection circuit, and
protective interlock circuit for forward/reverse operation or upper/lower limit positioning.
(2) If the following status (a) or (b) occurs, the system will behave accordingly.
(a) When overcurrent or overvoltage protection of the power supply module is activated, the
outputs (Y) from the user program and writing to the buffer memory are disabled, and all
outputs are turned off.
(b) When the C Controller module detects an error such as a watchdog timer error by the self-
diagnostic function, the outputs (Y) from the user program and writing to the buffer memory
are disabled. Whether to hold or turn off all outputs can be set by parameters.
All outputs may turn on when an error occurs in the part, such as I/O control part, where the C
Controller module cannot detect any error.
To ensure safety operation in such a case, provide a safety mechanism or a fail-safe circuit
external to the C Controller module. For a fail-safe circuit example, refer to "CHAPTER 6
PREPARATORY PROCEDURES AND SETTING" in this manual.
WARNING
CAUTION
Indicates that incorrect handling may cause hazardous conditions,
resulting in death or severe injury.
Indicates that incorrect handling may cause hazardous conditions,
resulting in minor or moderate injury or property damage.

A- 2
[Design Precautions]
WARNING
(3) Outputs may remain on or off due to a failure of an output module relay or transistor.
Configure an external circuit for monitoring output signals that could cause a serious accident.
In an output module, when a load current exceeding the rated current or an overcurrent caused by a
load short-circuit flows for a long time, it may cause smoke and fire. To prevent this, configure an
external safety circuit, such as a fuse.
Configure a circuit so that the C Controller system is turned on first and then the external power
supply. If the external power supply is turned on first, an accident may occur due to an incorrect
output or malfunction.
For the operating status of each station after a communication failure, refer to the relevant manuals
for the network.
Incorrect output or malfunction may result in an accident.
For the following controls, configure an interlock circuit in the user program to ensure that the entire
system will always operate safely.
(1) Changing data of a running C Controller module from the development environment (personal
computer) connected
(2) Changing the operating status
(3) Operation from the development environment (personal computer)
Especially, in the case of a control from an external device to a remote C Controller module,
immediate action cannot be taken for a problem on the C Controller module due to a communication
failure.
To prevent this, configure an interlock circuit in the user program, and determine corrective actions to
be taken between the external device and C Controller module in case of a communication failure.
To maintain the safety of the C Controller system against unauthorized access from external devices
via the network, take appropriate measures. To maintain the safety against unauthorized access via
the Internet, take measures such as installing a firewall.
When configuring the system, do not leave any slot empty on the base unit.
If a slot is to be left empty, attach a blank cover (QG60).
Failure to do so may cause internal parts of the mounted modules to fly apart during a short-circuit
test or when an excess current or voltage is applied to an external I/O part by mistake.

[Design Precautions]
[Installation Precautions]
CAUTION
Do not install the control lines or communication cables together with the main circuit lines or power
cables.
Keep a distance of 100mm (3.94 inches) or more between them.
Failure to do so may result in malfunction due to noise.
When a device such as a lamp, heater, or solenoid valve is controlled through an output module, a
large current (approximately ten times greater than normal) may flow when the output is turned from
off to on. Take measures such as replacing the module with one having a sufficient current rating.
After the C Controller module is powered on or is reset, the time taken to enter the RUN status varies
depending on the system configuration, parameter setting, and/or program size.
Design circuits so that the entire system will always operate safely, regardless of the time.
