[Design Precautions]
zWhen a safety programmable controller detects an error in an external power
supply or a failure in programmable controller 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.
zCreate short current protection for a safety relay, and a protection circuit such
as a fuse, and breaker, outside a safety programmable controller.
zWhen data/program change, or status control is performed from a PC to a
running safety programmable controller, create an interlock circuit outside the
sequence program and safety programmable controller to ensure that the
whole system always operates safely.
For the operations to a safety programmable controller, 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.
zAll 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 programmable controller system may cause
malfunctions and safety operation cannot be guaranteed.
zWhen a safety remote I/O module has detected CC-Link Safety error, it turns
off all the outputs. Note that the outputs in a sequence program are not
automatically turned off. If 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.
zTo inhibit restart without manual operation after safety function was performed
and outputs were turned OFF, create an interlock program which uses a reset
button for restart.

[Installation Precautions]
zDo 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 malfunctions.
zUse a safety programmable controller in the environment that meets the
general specifications described in this manual.
Using this programmable controller 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.
zWhile 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.
