A - 1
[Design Precautions]
DANGER
When a safety PLC detects an error in an external power supply or a failure in PLC main module, it
turns off all the outputs.
Create an external circuit to securely stop the power of hazard by turning off the outputs.Incorrect
configuration may result in an accident.
Create short current protection for a safety relay, and a protection circuit such as a fuse, and
breaker, outside a safety PLC.
When data/program change, or status control is performed from a PC to a running safety PLC,
create an interlock circuit outside the sequence program and safety PLC to ensure that the whole
system always operates safely.
For the operations to a safety PLC, pay full attention to safety by reading the relevant manuals
carefully, and establishing the operating procedure.
Furthermore, for the online operations performed from a PC to a safety CPU module, the corrective
actions against a communication error due to a cable connection fault, etc. should be predetermined
as a system.
All output signals from a safety CPU module to the CC-Link Safety system master module are
prohibited to use.
These signals can be found in the CC-Link Safety System Master Module User's Manual.
Do not turn ON or OFF these signals by sequence program, since turning ON/OFF these output
signals of the PLC system may cause malfunctions and safety operation cannot be guaranteed.
When a safety remote I/O module has detected a CC-Link Safety error, it turns off all the outputs.
Note that the outputs in a sequence program are not automatically turned off.
If a CC-Link Safety error has been detected, create a sequence program that turns off the outputs in
the program.
If the CC-Link Safety is restored with the outputs on, it may suddenly operate and result in an
accident.
To inhibit restart without manual operation after safety functions was performed and outputs were
turned OFF, create an interlock program which uses a reset button for restart.
CAUTION
Do not bunch the wires of external devices or communication cables together with the main circuit or
power lines, or install them close to each other.They should be installed 100 mm (3.94 inch) or more
from each other.Not doing so could result in noise that would cause erroneous operation.
A - 2
[Installation Precautions]
CAUTION
Use a safety PLC in the environment that meets the general specifications described in this manual.
Using this PLC in an environment outside the range of the general specifications could result in
electric shock, fire, erroneous operation, and damage to or deterioration of the product.
While pressing the installation lever located at the bottom of module, insert the module fixing tab into
the fixing hole in the base unit until it stops. Then, securely mount the module with the fixing hole as
a supporting point.
Incorrect loading of the module can cause a failure or drop.
Secure the module to the base unit with screws.
Tighten the screw in the specified torque range.
If the screws are too loose, it may cause a drop of the screw or module.
Over tightening may cause a drop due to the damage of the screw or module.
Completely turn off the externally supplied power used in the system before mounting or
removingthe module.
Not doing so could result in damage to the product.
Do not directly touch the module's conductive parts or electronic components.
Doing so may cause malfunctions or a failure.
[Wiring Precautions]
DANGER
Be sure to shut off all phases of the external supply power used by the system before wiring.
Not completely turning off all power could result in electric shock or damage to the product.
When energizing or operating the module after installation or wiring, be sure to close the attached
terminal cover.
Not doing so may result in electric shock.
A - 3
[Wiring Precautions]
CAUTION
Be sure to ground the FG terminals and LG terminals to the protective ground conductor.
Not doing so could result in electric shock or erroneous operation.
Use a solderless terminal with insulation sleeve for wiring of a terminal block.
Use up to two solderless terminals for a single terminal.
Use applicable solderless terminals and tighten them with the specified torque.
If any solderlessspade terminal is used, it may be disconnected when the terminal screw comes
loose, resultingin failure.
Wire the module correctly after confirming the rated voltage and terminal layout.
Connecting a power supply of a different rated voltage or incorrect wiring may cause a fire or failure.
Tighten a terminal block mounting screw, terminal screw, and module fixing screw within the
specified torque range.
If the terminal block mounting screw or terminal screw is too loose, it may cause a short circuit, fire,
or malfunctions.
If too tight, it may damage the screw and/or the module, resulting in a drop of the screw or module, a
short circuit or malfunctions.
If the module fixing screw is too loose, it may cause a drop of the screw or module.
Over tightening the screw may cause a drop due to the damage of the screw or module.
Be sure there are no foreign substances such as sawdust or wiring debris inside the module.
Such debris could cause a fire, failure, or erroneous operation.
The module has an ingress prevention label on its top to prevent foreign matter, such as wire offcuts,
from entering the module during wiring.
Do not peel this label during wiring.Before starting system operation, be sure to peel this label
because of heat dissipation.
Install our PLC in a control panel for use.
Wire the main power supply to the power supply module installed in a control panel through a
distribution terminal block.
Furthermore, the wiring and replacement of a power supply module have to be performed by a
maintenance worker who acquainted with shock protection.
(For the wiring methods, refer to Section 10.3.)

OVERVIEW
(2) The safety CPU operation mode is equipped for safe system operation
The CPU module is equipped with two safety CPU operation modes. "SAFETY
MODE" for safe system operation and "TEST MODE" for system construction and
maintenance.
These two modes prevent the user's erroneous operations for safe system operation.
(a) SAFETY MODE
SAFETY MODE is a mode for safe system operation. This mode prohibits the
write operation from a programming tool and the device test operation during the
system operation.
(b) TEST MODE
TEST MODE is a mode for maintenance. This mode enables the write operation
from a programming tool and the device test operation to debug or maintain the
sequence program.
For the details of operations available in the SAFETY MODE and TEST MODE, refer
to the following manual.
QSCPU User's Manual (Function Explanation, Program Fundamentals)
(3) Enriched operation history and error history
The CPU module can record a total of 3000 details of the CPU module operation by
the user and errors occurred in the CPU module or CC-Link Safety as operation/error
history data.
Recording the details of the CPU module operation by the user into the operation/
error history clarifies the occurrence order of operations and errors.
Troubleshooting becomes easier by confirming the operation/error history.
The contents recorded in the operation/error history are shown in Table1.2.
